History of Haiti
Following the arrival of Europeans, La Hispaniola's indigenous population suffered greatly to near extinction, in possibly the worst case of depopulation in the Americas. A commonly accepted hypothesis attributes the high mortality of this colony in part to European diseases to which the natives had no immunity. A small number of Taínos were able to survive and set up villages elsewhere. Spanish interest in Hispaniola began to wane in the 1520s, as more lucrative gold and silver deposits were found in Mexico and South America. Thereafter, the population of Spanish Hispaniola grew at a slow pace.
Slavery
In order to establish itself as an American empire, Spain had to fight against the relatively powerful civilizations of the New World. The Spanish conquest of the indigenous peoples in the Americas included using the Natives as forced labour. The Spanish colonies were the first Europeans to use African slaves in the New World on islands such as Cuba and Hispaniola (see Atlantic slave trade.) Bartolomé de las Casas, a 16th-century Dominican friar and Spanish historian, participated in campaigns in Cuba (at Bayamo and Camagüey) and was present at the massacre of Hatuey; his observation of that massacre led him to fight for a social movement away from the use of natives as slaves. Also, the alarming decline in the native population had spurred the first royal laws protecting the native population (Laws of Burgos, 1512–1513).
