In 1501
Isabella I of Castile declared Native Americans as subjects to the Crown, and so, as Castilians and legal equals to Spanish Castilians. This implied that enslaving them was illegal except under very specific conditions. It also allowed the establishment of
encomiendas, since the
encomienda bond was a right reserved to full subjects to the crown. In 1503, the crown began to formally grant
encomiendas to conquistadors and officials as rewards for service to the crown. The system of
encomiendas was aided by the crown's organizing the Indigenous into settlements known as
reducciones, with the intent of establishing new towns and populations. Each
reducción had a native chief responsible for keeping track of the labourers in his community. The
encomienda system did not grant people land, but it indirectly aided in the settlers' acquisition of land. As initially defined, the
encomendero and his heirs expected to hold these grants in perpetuity. After a major Crown reform in 1542, known as the
New Laws,
encomendero families were restricted to holding the grant for two generations. When the Crown attempted to implement the policy in Peru, shortly after the 1535 Spanish conquest, Spanish recipients rebelled against the Crown, killing the viceroy,
Blasco Núñez Vela. In Mexico, viceroy
Antonio de Mendoza decided against implementing the reform, citing local circumstances and the potential for a similar conqueror rebellion. To the crown he said, "I obey crown authority but do not comply with this order." The
encomienda system was ended legally in 1720, when the crown attempted to abolish the institution. The
encomenderos were then required to pay remaining
encomienda labourers for their work. The
encomiendas became very corrupt and harsh. In the neighborhood of La Concepción, north of Santo Domingo, the
adelantado of Santiago heard rumors of a 15,000-man army planning to stage a rebellion. Upon hearing this, the
adelantado captured the
caciques involved and had most of them hanged. Later, a chieftain named
Guarionex laid havoc to the countryside before an army of about 3,090 routed the
Ciguana people under his leadership. Although expecting Spanish protection from warring tribes, the islanders sought to join the Spanish forces. They helped the Spaniards deal with their ignorance of the surrounding environment. As noted, the change of requiring the
encomendado to be returned to the crown after two generations was frequently overlooked, as the colonists did not want to give up the labour or power. According to the
Codice Osuna, one of many colonial-era
Aztec codices (Indigenous manuscripts) with native pictorials and alphabetic text in
Nahuatl, there is evidence that the Indigenous were well aware of the distinction between Indigenous communities held by individual
encomenderos and those held by the Crown. ==Reform and abolition==
