Francisco de Orellana
Francisco de Orellana (1511, Trujillo, Crown of Castile – November 1546, Amazon River) was a Spanish explorer and conquistador. He completed the first known navigation of the entire length of the Amazon River, which initially was named "Rio de Orellana." He also founded the city of Guayaquil in what is now Ecuador.
Background
Born at Trujillo (various birth dates, ranging from 1490 to 1511, are still quoted by biographers), Orellana was a close friend, and possibly a relative of Francisco Pizarro, the Trujillo-born conquistador of Peru (his cousin, according to some historians). He traveled to the Indies (probably in 1527). Orellana served in Nicaragua until joining Pizarro's army in Peru in 1533, where he supported Pizarro in his conflict with Diego de Almagro (1538). After the victory over Almagro's men, he was appointed governor of La Culata and re-established the town of Guayaquil, previously founded by Pizarro and repopulated by Sebastián de Belalcázar.
(During the civil war he sided with the Pizarros and was Ensign General of a force sent by Francisco Pizarro from Lima in aid of Hernando Pizarro. He was granted land at Puerto Viejo, on the coast of Ecuador.)
