The Atlantic slave trade brought Africans to Puerto Rico in the early 1500s. Some of the first slave rebellions took place on the island of Puerto Rico. Until 1846, Africanos on the island had to carry a libreta to move around the island, like the passbook system in apartheid South Africa. In Puerto Rico, you will find large communities of descendants of the Yoruba, Bambara, Wolof and Mandingo people. Puerto Rican culture is inherently African culture.
