Arlington County, or simply Arlington, is a county in the U.S. state of Virginia. The county, which is located in the Washington metropolitan area and the broader Northern Virginia region, is positioned directly across the Potomac River from Washington, D.C., the national capital, on the river's southwestern bank. The smallest self-governing county in the United States by area, Arlington County has both suburban and urbanized districts. Its urban areas are located in proximity to several Washington Metro stations and lines. Arlington's seat of government is located in the Court House neighborhood, which hosts many of its administrative offices and the county courthouse.
Arlington was originally inhabited by the Nacotchtank people prior to the establishment of the Colony of Virginia in 1606. English colonists began settling in Arlington by the 1670s; the area was designated as part of Fairfax County in 1742. The colonial-era economy was mostly based in tobacco agriculture operated with enslaved labor and indentured servants on large plantations. Following the end of the Revolutionary War, Arlington's planters and yeoman farmers transitioned to other crops. Virginia ceded present-day Arlington to help form the District of Columbia, and beginning in 1801, the area was known as Alexandria County. It was eventually retroceded back to Virginia in 1847 as a result of pressure from Alexandria, which was the county's primary commercial center.
During the Civil War, Arlington formed part of the Union's defenses of Washington, which devastated its landscape and economy. Virginia's Reconstruction-era Constitution of 1870, in addition to administratively separating Arlington from Alexandria, empowered its black community to participate in local and state elections, which changed the political dynamics of the county until local conservative Southern Democrats succeeded in reestablishing white supremacy by the 1880s. This facilitated the institution of Jim Crow laws and racial segregation in Arlington by the early 20th century. Developers and local politicians further ingrained these practices in Arlington as it experienced a boom in suburbanization with its expanding interurban trolley network starting in the 1880s and a continued influx of federal employees into the 1950s. Despite opposition from Virginia's massive resistance campaign and other groups, Arlington became the first county in Virginia to desegregate its schools in 1959, and its businesses in 1960, after a series of sit-in protests.
Arlington's modern economic development has been greatly influenced by its Metrorail lines, which through deliberate planning starting in the 1960s have become the center of its urban corridors. Many federal government agencies and complexes, including the Pentagon, which houses the headquarters of the United States Department of Defense, are based in Arlington. Government contractors that serve these organizations and others in the Washington metropolitan area, such as Boeing and RTX Corporation, are also located in the county. While the public sector is a primary driver of Arlington's economy, tech firms with private sector operations, including Amazon, have established regional headquarters or offices in Arlington's business districts over the past several decades. Institutions of higher education with main or satellite campuses in the county include George Mason University, Marymount University, the University of Virginia, and Virginia Tech. Arlington is also known as the location of Arlington National Cemetery, a military cemetery established in 1864 where more than 400,000 members of the U.S. Armed Forces are buried. Sites at the cemetery such as the Tomb of the Unknown Soldier attract thousands of visitors annually. Other prominent military memorials located in Arlington include the Marine Corps War Memorial and Air Force Memorial.
History
Native American settlement
Arlington County was inhabited by prehistoric Native American cultures from the arrival of the Paleo-Indians 10,000 years before European colonization. Archeological evidence, including pottery fragments, tools, and arrowheads, suggests sporadic habitation during the Archaic Period, with more permanent communities during the Formative stage and Early Woodland period. Some objects unearthed during archeological digs have been found to be from as far as southern Ontario, indicating the existence of a trade route that ran through the area.
When John Smith made contact in 1608, Arlington was populated by the Nacotchtank, an Eastern Algonquian-speaking people that were likely part of the Powhatan Confederacy. He identified a village named Nameroughquena near the present-day 14th Street bridges. The Nacotchtank farmed, hunted, and fished along the nearby Anacostia River, where they had more villages.
Later in the 17th century, the Nacotchtank became involved in the regional beaver trade instigated by Henry Fleete, which, while enabling the Nacotchtank to build wealth, undermined traditional social structures and ultimately weakened them. Further pressures, including population loss due to the spread of infectious diseases from Europeans, warfare with encroaching British colonizers, and conflict with Native American tribes in northern regions, forced the Nacotchtank to abandon their homeland. By 1679, they had fully left the area and were absorbed into the Piscataway.
Colonial era
Colonists began migrating from Jamestown and towards the Potomac River between 1646 and 1676, during which land speculation in the region increased substantially. Early grants were issued in the mid-17th century by the Governor on behalf of the Crown to prominent figures of Virginia society; many never inhabited their landholdings during this period. The first "seated" grant in the area was the Howson Patent, which John Alexander purchased from Captain Robert Howson on November 13, 1669, and populated with tenants by 1677. With the establishment of the Northern Neck Proprietary after the restoration of Charles II in 1660, future land grants in the region were made by inheritors of Northern Neck, namely the Lords Fairfax.
After colonists depopulated the area in the aftermath of Bacon's Rebellion in 1676, migration to Northern Neck began to grow by the end of the 17th century. The increase in population justified the formation of Prince William County from parts of Stafford County in 1730, and in 1742 Fairfax County, of which present-day Arlington County was part. Early settlement patterns were defined by large plantations along waterways, where planters built wharfs that provided access to colonial trade networks. This included Abingdon Plantation, which was established by John Alexander's grandson Gerard by 1746 and was the Arlington area's first mansion house. Log cabins, such as the home built by John Ball in the mid-18th century, were common among Arlington's yeoman farming community.
Indentured servants and enslaved labor worked the land, the latter of which are first documented being in the Arlington area in 1693 and were owned by the wealthiest planters, such as the Masons and Washingtons. Tobacco was the dominant crop grown in Arlington until local soil was exhausted by the late 18th century, motivating tobacco planters to move further inland; remaining farmers turned to growing alternatives such as corn. Colonists also built gristmills along Arlington's creeks and engaged in fishing along the Potomac. Rudimentary roads, some of which were first established by Native Americans, and ferries along the Potomac connected residents and plantations with emerging towns such as Alexandria and Georgetown. The former served as the region's primary shipping and commercial district.
Revolutionary war and formation of federal district
The Stamp Act and Townshend Acts passed by the Parliament of Great Britain in the 1760s motivated planters and farmers in Fairfax County, including George Mason, George Washington, and members of the Ball family to sign agreements not to import or purchase British goods in protest. Mason later authored the Fairfax Resolves in 1774 in opposition to the policies, which were adopted by him and other landowners.
Following the Richmond Convention in 1776, Fairfax County established a Committee of Safety that collected taxes for the war effort and enforced bans on trade with Britain. Local Fairfax militia formed before the war were dissolved after the Richmond Convention ordered for the organization of a regular state force in July 1775. Men were recruited from Fairfax County and joined the Virginia state regiment that were incorporated into the Continental Army by 1776. While the area did not see significant action during the war, Alexandria was the home port for part of the Virginia State Navy; some ships operated as privateers. Part of Rochambeau's forces likely camped near Theodore Roosevelt Island on their way to Yorktown in 1781.
After American independence from the British Empire was achieved following the Treaty of Paris and the Constitution was instituted in 1789, the federal government set about establishing the United States' seat of government, which Article 1, Section 8 enabled through the power to acquire an area of no more than ten square miles for the nation's capital. The Residence Act passed by Congress on July 17, 1790, which decreed that the federal district be located on the Potomac River between the "mouths of the Eastern Branch and the Conogochegue", settled the rivalry between states on claiming the location of the capital city. President George Washington commissioned a survey to define its borders, which reached down to Hunting Creek and were consequently beyond the Residence Act's limits; this required an amendment that was passed on March 3, 1791.
In 1789, Virginia had offered to cede ten square miles or less and provide funding for the construction of public buildings. Congress accepted this as a part of the federal district, but specified that no public buildings would be erected in the Virginia section of the capital. Boundary stones were placed at one miles intervals along the borders of the district starting on April 15, 1791. The federal government and Congress moved to the new city of Washington within the District of Columbia in 1800; the Virginia section, which included Alexandria, became known as Alexandria County through the District of Columbia Organic Act of 1801.
Antebellum period
In the early 19th century, the land outside of Alexandria, termed the "country part" of Alexandria County and representative of present-day Arlington, remained rural and dominated by several large plantations and smaller farms. Migration from northern states, including New York and Pennsylvania, brought investment and improved farming methods. Small communities established along the intersections of Alexandria County's growing road network, including Ball's Crossroads, became gathering places for local residents. The county's free black population, which consisted of 235 individuals outside of Alexandria in 1840, lived throughout the area in small clusters and among white neighbors. While agriculture, particularly of corn and grain, was the county's main economic output in the first half of the 19th century, some residents worked in various trades and factories in Alexandria. Other non-farming occupations included fishing and brickmaking.
Enslaved African Americans consisted of around 26% of the population in 1810, working on properties such as George Washington Parke Custis's Arlington Plantation, which Custis established with his inheritance from John Parke Custis, step-son of George Washington, in 1802; this included 18,000 acres of land across Virginia and 200 slaves, 63 of which worked on building and maintaining the plantation. The prominent African American Syphax family, whose matriarch Maria Carter Syphax was an illegitimate daughter of Custis and enslaved maid Arianna Carter, originated as enslaved servants on the Arlington estate; Custis later manumitted Maria and her children in 1845 and granted them 17 acres of land. Custis was the largest slave owner in the area until his death in 1857.
The population share of the enslaved dropped to around 20% by 1840 as a consequence of the continued movement away from labor-intensive tobacco farming and the slave trade with Deep Southern states and territories. Alexandria became a national center of this trade, with firms like Franklin & Armfield pioneering in the trafficking of enslaved people from around the Chesapeake region to New Orleans and the Forks in the Road slave market in Natchez, where they were sold to the Deep South's growing cotton plantations.
Major infrastructure, including the Chain Bridge, Long Bridge, and Aqueduct Bridge, was built in the first half of the 19th century to better connect the District of Columbia with the surrounding region. Toll roads were established between Alexandria, Georgetown, Leesburg, and other major settlements to facilitate the improvement and maintenance of thoroughfares, some of which also funded bridge construction. The Alexandria Canal, which via the 1843 Aqueduct Bridge connected Alexandria to the Chesapeake and Ohio Canal in Georgetown, was opened in 1846. Alexandria County's first railway, the Alexandria and Harper's Ferry Railroad, was chartered in 1847; it later became part of the Washington and Old Dominion Railroad. Infrastructure expansion drove the Jackson City speculative development, which was established in 1835 by a group of investors from New York at the foot of Long Bridge. Their vision of Jackson City as a rival port to Georgetown and Alexandria was never realized, as the settlement failed to receive a charter from Congress owing to opposition from residents Georgetown and Washington.
Retrocession
The reintegration of Alexandria County into Virginia had been raised intermittently since the formation of the District, particularly by townspeople in Alexandria. Congressional debate of the issue began with discussion of the 1801 Organic Act and its implications, focusing on the lack of political rights afforded to District residents, who were not permitted to vote or have representation in Congress. Economic concerns relating to insufficient federal investment in infrastructure like the Alexandria Canal, which left Alexandria heavily indebted, motivated merchants and leaders in Alexandria to consider retrocession by the 1830s. The argument went that rejoining Virginia would bring financial relief to the municipal budget, greater support for economic development, restored political rights, and free Alexandria County from "antiquated" statutes Congress had inherited from older colonial laws and not updated.
Congress's failure to recharter banks in the District further frustrated Alexandria's business community, and in 1840 the Common Council of Alexandria convened a county-wide referendum on retrocession, with a majority voting in favor. After several years of lobbying by a committee of Alexandrians, the Virginia General Assembly introduced state legislation in July 1846 to accept Alexandria County back into Virginia territory if Congress agreed. Congress passed the Retrocession Act later that month that authorized the return of Alexandria County to Virginia pending another county referendum.
The referendum, held on September 1 and 2, passed with overwhelming support from Alexandrians, but was rejected by residents in the broader county; many in Alexandria County questioned the constitutionality of retrocession and felt marginalized by a movement that was primarily driven by Alexandria's business interests. George Washington Parke Custis, who had originally opposed retrocession due to concerns about the county's finances, changed sides after the Virginia General Assembly agreed to take on the debt incurred by the Alexandria Canal construction. Alexandria County was officially returned to Virginia on March 13, 1847, after the Virginia General Assembly passed the state's retrocession bill.
Beyond the freeholding whites in Alexandria County who were able to participate in the referendum, Alexandria County's free black community was also opposed to retrocession, as they anticipated the pro-slavery Virginia government would encroach upon their rights and institutions. This fear was realized soon after retrocession, when Virginia closed most of Alexandria County's black schools and imposed Black Codes upon all free African Americans.
While not mentioned prominently in contemporary debates about retrocession, modern historians and other figures have since argued that the future of slavery in Alexandria and Virginia more broadly was a significant factor. Growing domestic and international abolitionist sentiments stoked fears in Alexandria that slavery would eventually be abolished in the District of Columbia and by extension threaten the town's lucrative slave trade. This ultimately came to pass as a part of the Compromise of 1850, which banned Washington's slave trade.
In 1907, Alexandria County attorney Crandal Mackey wrote that, given Alexandria County's existence as a destination for runaway enslaved people, Alexandrians thought they would be better served by the enforcement of slaveowners' property rights that would be guaranteed by Virginia's pro-slavery government. Retrocession also enabled the pro-slavery faction of the Virginia General Assembly to add two safe seats, strengthening their position against non-slave owning, abolitionist-leaning constituencies in Western Virginia.
Civil War
The "country part" of Alexandria County leaned strongly Unionist, as indicated by the results of the May 23, 1861 vote held on the ratification of Virginia's Ordinance of Secession; despite reports of voter intimidation from secessionists, two-thirds voted against the Ordinance. This was in part a result of the migration from northern states into Arlington County during the first half of the 19th century, some of whom were sympathetic to abolitionism and the Republican Party. Regardless, Virginia voted overwhelmingly in favor of secession and joined the Confederacy. Robert E. Lee, a colonel in the U.S. Army, son-in-law of George Washington Parke Custis, and owner of Arlington Plantation following Custis's death, left for Richmond with his family on April 22, 1861, to accept command of Virginia's army.
Union occupation
The proximity of Alexandria County to Washington, as well as the direct lines of sight it offered to important landmarks, necessitated the construction of defenses to protect the capital. After engaging in brief reconnaissance activities, the Union army moved three units into Alexandria County on the night of May 23, 1861, with commanding officer General Joseph K. Mansfield establishing a regional headquarters at Arlington Plantation. Work began immediately on a series of fortifications that eventually became the Arlington Line of the Civil War Defenses of Washington. These included forts and rifle trenches along Arlington Heights, thoroughfare intersections, and bridgeheads. The Confederate victory at the Battle of Bull Run in July 1861 increased the urgency of completing Washington's defenses, which were mostly finished by the end of that year. The Union army also built roads, including Military Road, to enable improved communications and transport along the defensive line. Construction of forts and improvements continued up to 1863.
The Union occupation significantly altered the landscape of Alexandria County. Defensive works required the logging of forests and trenches that cut through farmland. Union troops repurposed private homes and public buildings as hospitals and other facilities. Many properties were left decimated following troop encampments and the razing of structures for timber and other resources. Confederate sympathizers, many of whom were local officials, left after the arrival of Union soldiers, which created gaps in governance; General William Reading Montgomery addressed this by creating a military court that tried military and civilian cases, which was eventually closed after local criticism.
Military engagements
Throughout the war, Alexandria County only saw minor skirmishes between Union and Confederate forces. Confederate parties began engaging in guerrilla tactics against Union outposts in early June 1861, including a minor clash at Arlington Mill on June 2. The most significant battle took place in August 1861 at Ball's Crossroads, when Confederates stationed at Munson's Hill in Fairfax County penetrated the Union line as far as Hall's Hill, which they shelled before being driven back by Union cavalry. Union forces also operated the Balloon Corps in Alexandria County until 1863 to perform aerial reconnaissance on nearby Confederate encampments and activities.
Arlington Cemetery and Freedman's Village
Congress's June 1862 enactment of an assessment of taxes owed by Southern property owners, and subsequent enforcement of tax collection, resulted in the Lee family owing $92.07 on Arlington plantation. Mary Anna Custis Lee sent a relative to pay this, which was rejected given her absence. The federal government then seized Arlington estate and purchased it at a public auction held on January 11, 1864, on orders from President Abraham Lincoln. Following this purchase, the Quartermaster General's Office, in search of a burial site for the many Union casualties at the Battle of the Wilderness, selected Arlington in May 1864 for its scenic beauty and association with Robert E. Lee. The first military burial took place on Mary 13, 1864, around one month before the cemetery was officially established.
The rise in contraband migrants from the South into Washington, and the overcrowded camps that accommodate them, motivated the Department of Washington to establish the Freedman's Village settlement for emancipated enslaved people on the grounds of Arlington. Founded on December 4, 1863, Freedman's Village, unlike other contraband camps, was envisioned as a model community for African Americans transitioning out of enslavement. The Village provided its inhabitants with instruction in trades, housekeeping, and general education; many were employed by the Union Army and paid a regular wage. Secretary of State William H. Seward often toured prominent visitors around Freedman's Village to demonstrate the Villagers' progress. Many organizations, including churches and fraternities, were founded by Villagers during this period that became the social foundation of Arlington's black community.
Reconstruction through 1900
Years of occupation by Union troops left Alexandria County's economy in poor condition after the war; thousands of acres of farms and woodland had been destroyed. Local landowners who applied for compensation through the Southern Claims Commission generally received much less than they requested. Some financially ruined residents sold off parcels of land at low rates to formerly enslaved people migrating into Alexandria County from rural Virginia and Maryland, eventually creating black enclaves like Hall's Hill.
Changes in municipal governance in Virginia's 1870 Constitution required that all counties be divided into three or more districts, excluding any cities with a population greater than 5,000. This administratively separated Alexandria from the rest of the county and divided Alexandria County into the Arlington, Jefferson, and Washington Districts, with each having its own elected offices, public schools, and other facilities. The Reconstruction Amendments passed along with the 1870 Constitution enabled Alexandria County's eligible black voters to participate in district and county-level elections, resulting in local black politicians, such as John B. Syphax, rising to elected office. This was especially the case in the Jefferson District, which contained Freedman's Village and became a center of black political power in the county.
While this constituency was initially associated with the Republican Party, the rise of Virginia's Conservative Party, which opposed black suffrage and other Reconstruction-era reforms, eventually led to the Republicans abandoning their commitments to racial equality. Dissatisfied black voters, as well as white working class communities associated with the labor movement, flocked to the Readjuster Party, a newly established progressive populist party that opposed Virginia's old planter establishment and controlled the General Assembly by 1879.
White conservatives that wanted to reinstate their political and social dominance challenged the ascendency of Alexandria County's black community by the 1880s. Through an orchestrated smear campaign in the local press, they contributed to the closure of Freedman's Village in 1887, which had by that point lost the support of the federal government. White conservatives also prevented elected black officials from taking office either through claims about "inexperience" or identifying failed payments of election dues. This occurred during a broader political shift in Virginia towards Southern Democrats, who successfully undermined the Readjuster Party's interracial coalition with a reactionary, racist platform by 1885.
Starting in the 1880s, local railroad companies began constructing an interurban trolley system in Alexandria County that eventually provided commuter services to Washington by 1907. This facilitated the establishment of suburban subdivisions, such as Clarendon, along the trolley lines by 1900. Population growth, as well as the inconvenience of running the county's affairs from the old courthouse in Alexandria, drove the General Assembly to enact legislation that enabled residents to vote if the courthouse should be relocated. After a majority voted in favor of the motion, the county's new courthouse was completed on the old site of Fort Woodbury in 1898.
20th century suburbanization and Jim Crow segregation
In the first several decades of the 20th century, Alexandria County, officially renamed to Arlington County after the Arlington estate in 1920, rapidly developed into a commuter suburb of Washington. The ten-year period between 1900 and 1910 saw the creation of 70 new communities and subdivisions. Community organizations were established in these neighborhoods to advocate for their residents. During this period, the City of Alexandria succeeded in annexing significant portions of Arlington's southern area in 1915 and 1929; further annexations were prevented by the General Assembly in 1930.
Developers and political figures such as Frank Lyon and Crandal Mackey, who were members of the Southern Progressive movement, advocated for county-wide infrastructure improvements and the removal of "areas of vice" to facilitate continued suburbanization. This included Rosslyn, an interracial neighborhood which had developed a series of gambling halls and saloons beginning in the 1870s. Lyon and Mackey established the Good Citizen's League in the 1890s, which consisted of Arlington's wealthiest and most influential residents, to push for these changes.
Consistent with other Southern Progressives during the Jim Crow era, the Good Citizen's League sought to modernize Arlington while maintaining its racial hierarchy through segregation and other means. League members conducted violent "clean up" raids, most infamously in Rosslyn in 1904, participated in the Virginia Constitutional Convention of 1901–02 that disenfranchised black voters through poll taxes, and developed white suburban subdivisions via racially restrictive housing covenants. By 1930, these figures also succeeded in changing Arlington's system of government, where the districts established in 1870 were abolished and replaced with a county board of five at-large members that appointed a county manager as chief executive. As intended, this diluted the voting power of Arlington's black population and enabled further institution of racial segregation.
While there were no lynchings in Arlington like elsewhere in the South during the nadir in American race relations, there were recorded instances of racial violence by whites against Arlington's black residents, particularly on its segregated trolley lines. One notable example took place in 1908, when two black passengers traveling to Falls Church, Sandy James and Lee Gaskins, were severely beaten and thrown from a trolley car by a crowd of white people; a mob of 300 white people then gathered in Ballston to search for them on account of an unsubstantiated rumor that James and Gaskins had attempted to derail the trolley. Gaskins was found and sentenced to 10 years in prison despite flimsy evidence, and James was never seen again; Arlington Sheriff Howard Fields later boasted that he had hit James in the head 25 times with a blackjack. Arlington also had an active Ku Klux Klan (KKK) presence during this period, who would participate in community parades and stage cross burnings near black neighborhoods.
The 1896 Plessy v. Ferguson U.S. Supreme Court decision that legalized "separate but equal" racial segregation enabled the Virginia Assembly to pass zoning ordinances in 1912 that created "segregation districts" throughout the state, which were adopted in Arlington. While these were eventually struck down by the 1917 Buchanan v. Warley decision, county planners and developers restricted the growth of black neighborhoods in other ways, including through Arlington's 1930 zoning ordinance that prevented further construction of more affordable multifamily housing in black communities. The effect of these policies was the stagnation of Arlington's black population, which declined from 38% of Arlington's population in 1900 to around 12% by 1930. Blacks were forced to concentrate in a few overcrowded enclaves as the county's white population increased rapidly with the growth of whites-only suburban subdivisions. These subdivisions gradually encroached upon black neighborhoods, and by 1950 only three black communities remained in the county; 11 had existed in 1900.
New Deal through Civil Rights
Beginning in the New Deal era, Arlington County experienced an inflow of federal workers. While the Great Depression stalled residential development, incoming government employees instigated further growth and the population doubled between 1930 and 1940. Public housing projects backed by the Federal Housing Administration, such as Colonial Village, were built across Arlington to help house its expanding population; consistent with Arlington's Jim Crow policies, these communities were closed off to Arlington's black residents and other minority groups. New Deal programs, such as the Public Works Administration, also supported the continued improvement of Arlington's infrastructure, including the completion of an overhauled sewer system in 1937 and renovations to local public schools. Rising car ownership caused the closure of Arlington's trolley lines during the 1930s; these were replaced with a public bus system. Washington National Airport, later renamed after President Ronald Reagan in 1998, opened in 1941 on land formerly occupied by the Abingdon Plantation.
Arlington's population increase fundamentally altered its politics. Its traditional Southern Democratic political establishment, which favored racial segregation and consisted of Southerners in the mold of Mackey and Lyon, was gradually replaced with more liberal, New Deal Democrats and white moderates. These figures fought for greater investment in public education and infrastructure in Arlington, often against opposition in Richmond, where the Democratic Party's socially and fiscally conservative Byrd Machine had dominated the General Assembly since the early 20th century. These developments coincided with a rising civil rights movement in Arlington, reflected in the establishment of its NAACP branch in 1940 and Green Valley resident Jessie Butler's legal challenge to Virginia's poll tax in 1949.
The entry of the U.S. into World War II drove expansion in government that had a significant impact on Arlington County. Massive facilities such as the Pentagon and Navy Annex were built to support military operations. These, along with infrastructure like the Shiley Memorial Highway, required the demolition of Queen City and East Arlington, two historic black communities that had been established shortly after the closure of Freedman's Village. The federal government at first housed displaced residents in several trailer camps after an intervention by First Lady Eleanor Roosevelt; poor living conditions resulted in both being closed by 1949. Roosevelt further pressured the Federal Public Housing Authority in 1944 to provide more housing to Arlington's African American community, resulting in the construction of a 44-unit public housing project in Johnson's Hill for black residents that year; many leaving the trailer camps moved into this property. By comparison, white residents had access to thousands of public housing units during this period, and none were housed in trailer camps.
Arlington's NAACP and other civil rights organizations continued fighting the county's prevailing racial segregation through a series of legal challenges, particularly after the 1954 Brown v. Board of Education U.S. Supreme Court ruling that struck down "separate but equal" segregation under Plessy v. Ferguson. Reactionary political forces and organizations, including Virginia's massive resistance program against racial integration in schooling led by former governor and Senator Harry F. Byrd and local Arlington hate groups such as George Lincoln Rockwell's American Nazi Party and the KKK, rose in opposition to this civil rights activism and Arlington's increasing liberalism.
A 1956 lawsuit by NAACP and three residents from Hall's Hill against Arlington's segregation in schooling initiated an extended legal fight that lasted until February 2, 1959, when Stratford Junior High School in Cherrydale was racially integrated with the admission of four black students. The integration, while tense, occurred with relative peace and was dubbed "the day nothing happened" in the local press. In 1960, the Cherrydale sit-ins organized by the Nonviolent Action Group at Howard University resulted in the desegregation of Arlington businesses, and with the passing of the Civil Rights Act of 1968, de jure racial housing discrimination in Arlington was officially outlawed.
Arrival of Metro
Arlington County experienced decelerated population growth starting in 1960 as a result of continued migration of residents out to newer suburbs in Fairfax and Montgomery counties; between 1970 and 1980, Arlington lost 21,865 residents. Factors involved in this population shift included new transportation infrastructure that made commuting from more distant communities possible, and white flight following the racial integration of Arlington's school system. This change caused its commercial districts, which were also facing competitive pressure from suburban malls, to enter a period of decline.
