Pedro Vilcapaza Alarcón, known as the "Untamed Puma," was born in Morco Orco, 20 kilometers from Azángaro, in June 1741.[1] His parents were Cleto Vilcapaza and Juana Alarcón. He was the second son and had several siblings: Toribio, Pedro, Gerónimo, Francisco, Manuel, and Antonia. Through his father, he descended from the caciques of Azángaro, and on his mother's side, he descended from the Spanish captain and encomendero Martín Alarcón.
Due to his mixed-race heritage and the influence of his maternal family, he gained admission to the Royal College of San Bernardo in Cusco, later completing his education at the San Francisco de Borja College. Upon finishing his studies, he joined the Royal Army of Peru as a soldier, eventually reaching the rank of cavalry sergeant.
On March 30, 1762, when he was 22 years old, he participated as a witness in the trial of the inhabitants of Moro Orco against the chief Diego Choquehuanca for the constant abuses of the latter against the indigenous people.
In August 1771, he returned to his homeland to dedicate himself to trade, achieving prosperity primarily through the transport of silver between Potosí and Cusco, a route that allowed him to forge a friendship with José Gabriel Condorcanqui. That year, he married Manuela Copacondori Choquehuanca, niece of the cacique Diego Choquehuanca. The marriage was childless, and Manuela soon left her husband. Some writings record a woman named Rosario as Vilcapaza's partner; they had a daughter named Leonarda.
