The encomienda was a 16th-century Spanish labour system that rewarded Spain's conquistadors with the labour of conquered non-Christian peoples. In theory, the conquerors would provide the labourers with benefits, including military protection and education. In practice, the conquered were subject to conditions that closely resembled instances of forced labour and outright slavery. The encomienda was first established in Spain following the Christian Reconquista, and it was applied on a much larger scale during the Spanish colonization of the Americas and the Spanish East Indies. Conquered peoples were considered vassals of the Spanish monarch. The Crown awarded an encomienda as a grant to a particular individual. In the conquest era of the early sixteenth century, the grants were considered a monopoly on the labour of particular groups of Indigenous peoples, held in perpetuity by the grant holder, called the encomendero; starting from the New Laws of 1542, the encomienda ended upon the death of the encomendero, and was replaced by the repartimiento.
