Marcos Xiorro was a slave, who in 1821 planned a slave revolt against the owners of sugar plantations and the Spanish colonial government in Puerto Rico. Even the plot didn't exactly work out the way it had to, it had a huge impact among slaves and is part of Puerto Rican history. We don't know exactly where Marcos was born, nor in what region of Africa he was captured, all we do know is that he was taken from Africa by the Spaniards and served a certain Vicente Andio, owner of a sugar plantation.
In Puerto Rico, the first slave rebellion as such happened in 1527, when a dozen slaves fought a battle against the Spanish colonizers. The rebellion was unsuccessful and the slaves managed to escape to the mountains to form communities of chestnuts where they cohabitated with the Taino (native people of the island). After the Haitian revolution, the French who had been beaten fled to the Dominican Republic and then went to Puerto Rico, where they settled and decided to make the island, one of the largest exporters of sugar. Towards 1873, slavery was abolished in Puerto Rico, and the majority of wealth amassed by the owners was through the exploitation of slaves. And more and more uprisings and disobedience were observed among the slaves, who were tired of living in the same way despite the abolition. And besides, after the success of the Haitian revolution (1791 - 1804), rumors spread among the Caribbean that the Haitians were plotting to attack all the Spanish colonies. These rumors terrified plantation owners as they had already escaped from Haiti.
