The encomienda (eŋkoˈmjenda) was a Spanish labour system that rewarded conquerors with the labour of conquered non-Christian peoples. The labourers, in theory, were provided with benefits by the conquerors for whom they laboured, including military protection and education. The encomienda was first established in Spain following the Christian reconquest of Moorish territories (known to Christians as the 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 to be a monopoly on the labour of particular groups of indigenous peoples, held in perpetuity by the grant holder, called the encomendero; following the New Laws of 1542, upon the death of the encomendero, the encomienda ended and was replaced by the repartimiento.
Encomiendas devolved from their original Iberian form into a form of "communal" slavery. In the encomienda, the Spanish Crown granted a person a specified number of natives from a specific community but did not dictate which individuals in the community would have to provide their labour. Indigenous leaders were charged with mobilising the assessed tribute and labour. In turn, encomenderos were to ensure that the encomienda natives were given instruction in Catholicism and the Spanish language, to protect them from warring tribes or pirates; to suppress rebellion against Spaniards, and maintain infrastructure. The natives provided tributes in the form of metals, maize, wheat, pork, and other agricultural products.
With the ousting of Christopher Columbus in 1500, the Spanish Crown had him replaced with Francisco de Bobadilla. Bobadilla was succeeded by a royal governor, Fray Nicolás de Ovando, who established the formal encomienda system. In many cases natives were forced to do hard labour and subjected to extreme punishment and death if they resisted.
