Koshi Province (Nepali: कोशी प्रदेश, romanized: Kōśī pradēśa) is an autonomous province of Nepal adopted by the Constitution of Nepal on 20 September 2015. It covers an area of 25,905 km2 (10,002 sq mi), which is about 17.5% of the country's total area. With the industrial city of Biratnagar as its capital, the province includes the major towns of Birtamod, Sundar Haraincha, Damak, Dharan, Itahari, Triyuga Municipality, and Mechinagar. It further hosts a number of Himalayan peaks including Mount Everest, Kangchenjunga (the third highest peak on Earth), Lhotse (the fourth highest peak), Makalu (the fifth highest peak), Cho Oyu (the sixth highest peak), and Ama Dablam.
The river Koshi, the largest river of the nation, and the Koshi Tappu wildlife reserve form the province's western boundary. The province is bordered by the Tibet Autonomous Region of China to the north, the Indian states of Sikkim and West Bengal to the east and Bihar to the south, and Bagmati Province and Madhesh Province to the west. The province also hosts the Koshi highway, which is one of the three crucial Nepalese north-south corridors that are designed to connect India and China via land.
Under the First-past-the-post voting system issued by the Constituency Delimitation Commission, Nepal, the province hosts 28 parliamentary seats and 56 provincial assembly seats. According to the 2021 Nepal census, there are around five million people in the province, with a population density of 190 per square kilometre. Per the earlier 2011 Nepal census, the province had approximately 4.5 million people.
Etymology
The province is named Koshi after the Koshi River, which is the largest river in the country. On 1 March 2023 the former temporary name of the province, Province No. 1, was changed to Koshi Province.
History
When King Mung Mawrong Hang came to prominence in the Terai lands of Limbuwan, he cleared much of the forest area in present-day Rangeli, east of Biratnagar, and built a town there. He named his Kingdom Morang after his name and rose to power.
Meanwhile, King Prithvi Narayan Shah was on a campaign to conquer all the hill kingdoms into his Empire (the Kingdom of Nepal). He attacked Limbuwan on two fronts. After the Limbuwan–Gorkha War from 1771 to 1774 AD, the Limbu ministers of Morang, and Limbu rulers of the ten principalities came to an agreement with the King of Gorkha. With the Limbuwan Gorkha treaty of 1774, Limbuwan was annexed to the Kingdom of Nepal.
The term district has been used in various ways throughout the modern history of Nepal.
At the end of the Rana regime, Nepal was divided into 32 districts. Eastern Nepal was composed of the following districts:
Morang District
Udayapur District
Ilam District
Dhankuta District
Bhojpur District
Okhaldhunga District
In 1956, the eastern districts of Nepal were grouped together into a region called the Aruṇ Kshetra or Arun Region, after the Arun River which flows through it. Arun Kshetra was made by combining the then five districts; it had total area of 18,000 km2 (7,000 sq mi) and a total population of 1.1 million people.
The five districts were:
Biratnagar District: including Sunsari District and Morang District
Dhankuta District: including Dhankuta District and Sankhuwasabha
Taplejung District: including Taplejung and Panchtharl
Mechi District: including Ilam District and Jhapa District
Bhojpur District: including Bhojpur District and Khotang District
In 1962, the administrative system once again was changed, abolishing the kshetra system. The country was restructured into 75 development districts and those districts were grouped together into zones. In 1972, what is now called Koshi Province was called the Eastern Development Region that was composed of 16 districts which were grouped into three zones: Koshi, Mechi and Sagarmatha.
In 2015, the Constitution was adopted which made 14 districts into an autonomous province which was temporarily named Province No. 1. At the cabinet meeting held on 17 January 2018, the city of Biratnagar was declared the interim capital of Province No. 1. On 6 May 2019, it was declared the permanent capital by a vote of two-thirds of the provincial Member of legislative assembly. On March 1, 2023, the province was named Koshi Province on passage of the bill in Parliament. Later, some protested the name "Koshi".
