The Atlantic slave trade began in the very early 1500s. Santo Domingo (present-day Dominican Republic) was the first place to transport African slaves in the Americas. The dying of Indigenous people in the island, caused the Spanish to quickly grant permission from Spain to use slaves to work the plantations. In 1510, the first sizable ship consisted of 250 Black Latinos (Spanish-speaking men ), 8 years later, African born slaves arrived in massive numbers. The slave and black population was so big that they would out-number whites from 9 out of 10. The first major slave revolt took place in Dominican Republic's hills in 1522. These Maroons were originally from the senegambian region of Africa; of which most were Muslims of the Wolof nation. Many centuries later the Maroon populations became so large that the only way whites could travel would be in large armed groups. Most of the Maroon populations established themselves in mostly in rivers, hills/mountains, coastal and in caves. The Congolese people were known to be very aggressive and naturally strong, they and many of the Mandingas, Wolofs, and Fulanis was the main ethnicity to have been born in Maroon villages.
