Pedro Arias de Ávila (pā´ŧħrō ä´ryäs dā ä´vēlä), known as Pedrarias (pāŧħrä´ryäs), c.1440–1531, Spanish colonial administrator. He was sent (1514) as governor to Darién (now part of Panama), then under the rule of Vasco Núñez de Balboa. A long quarrel between the two ended with Balboa's execution. Pedrarias's administration was notoriously harsh and cruel, but he extended the Spanish dominions and founded (1519) Panama City; he first aided, but later hindered, Francisco Pizarro and Diego de Almagro in their conquest of Peru. His name also appears as Pedrarias Dávila.
