de León to explore Puerto Rico and prospect for gold. In 1511, he fought under Ponce de León to repress the Carib and the Taíno, who had joined forces in Puerto Rico in a great revolt against the Spaniards. Garrido next joined Hernán Cortés in the Spanish conquest of Mexico. Another free African man who accompanied de León was Pedro Mejías. Mejías married a Taíno woman chief (a cacica), by the name of Yuisa. Yuisa was baptized as Catholic so that she could marry Mejías. She was given the Christian name of Luisa (the town Loíza, Puerto Rico was named for her). The peace between the Spanish and the Taíno was short-lived. The Spanish took advantage of the Taínos' good faith and enslaved them, forcing them to work in the gold mines and in the construction of forts. Many Taíno died, particularly due to epidemics of smallpox, to which they had no immunity. Other Taínos committed suicide or left the island after the failed Taíno revolt of 1511. Friar Bartolomé de las Casas, who had accompanied Ponce de León, was outraged at the Spanish treatment of the Taíno. In 1512 he protested at the council of Burgos at the Spanish Court. He fought for the freedom of the natives and was able to secure their rights. The Spanish colonists, fearing the loss of their labor force, also protested before the courts. They complained that they needed manpower to work in the mines, build forts, and supply labor for the thriving sugar cane plantations. As an alternative, Las Casas suggested the importation and use of African slaves. In 1517, the Spanish Crown permitted its subjects to import twelve slaves each, thereby beginning the African slave trade in their colonies. According to historian Luis M. Diaz, the largest contingent of African slaves came from the areas of the present-day Ghana,Togo, Benin, Nigeria; all these current countries are located in the Gulf of Guinea, area also known as the Slave Coast. The large majority were Yoruba and Igbo, ethnic groups from Nigeria, and Bantu from the Guinea. The number of slaves in Puerto Rico rose from 1,500 in 1530 to 15,000 by 1555. The slaves were stamped with a hot iron on the forehead, a branding which meant that they were brought to the country legally and prevented their kidnapping. African slaves were sent to work in the gold mines to replace the
