Francisco Pizarro

"In the 16th century the Spanish conquistadors tore into the New World of South America. Francisco Pizarro, an illiterate peasant solider who conquered Peru, was perhaps the most ruthless of these soldiers of fortune. In 15 years he and his followers killed thousands of indigenous Indians, wiped out the ruling Inca monarchy and enslaved an empire. These acts were committed in pursuit of power, gold and religious imperialism. Few men have changed the course of world history in such a violent, ruthless manner."
