the Santo Domingo colony. Many of the insurgents fled to the mountains and established what would become the first autonomous African Maroon community in America. With the success of this revolt, slave revolts continued and leaders emerged among the African slaves, such as Sebastían Lemba. This also included people already baptized Christian by the Spanish, as was the case of Juan Vaquero, Diego de Guzmán and Diego del Campo. The rebellions and subsequent escapes led to the establishment of African communities in the southwest, north and east of the island, including the first communities of African ex-slaves in western Hispaniola that was Spanish administered until 1697, when it was sold to France and became Saint-Domingue (modern-day Haiti). This caused some concern among slaveholders and contributed to the Spanish emigration to other places. Even as sugarcane increased profitability in the island, the number of escaped Africans continued to rise, mixing with Taíno people of these regions, and by 1530, Maroon bands were considered dangerous to the Spanish colonists, who traveled in large armed groups outside the plantations and left the mountainous regions to the Maroons. With the discovery of precious metals in South America, the Spanish abandoned their migration to the island of Hispaniola to emigrate to South America and Mexico in order to get rich, for they did not find much wealth there. Thus, they also abandoned the slave trade to the island, which led to the collapse of the colony into poverty. Still, during those years, slaves were used to build a cathedral that in time became the most oldest in the Americas. They build the monastery, first hospital and the Alcázar de Colón, and the Puerta de las Lamentaciones (). In the 1540s, Spanish authorities ordered the African slaves building a wall to defend the city from attacks by pirates who ravaged the islands. After 1700, with the arrival of new Spanish colonists, the Atlantic slave trade resumed. However, as industry moved from sugar to livestock, racial and caste divisions became less important, eventually leading to a blend of cultures—Spanish, African, and indigenous—which would form the basis of national identity for Dominicans. It is estimated that the population of the colony in 1777 was 400,000, of which 100,000 were Europeans and Criollos, 60,000 African, 100.000 mestizo, 60,000 zambo and 100,000 mulatto. The abolition of slavery At the end of the eighteenth century, fugitive African slaves from Saint-Domingue, the
