Vilchumlay was chieftain of Gualaceo, from where he witnessed the punitive actions of Emperor Atahualpa against the Cañari provinces for supporting his rival and brother Huáscar, legitimate heir to Emperor Huayna Cápac. In 1532, ambitioning freedom from Atahualpa's brutal rule and revenge for his attacks, Vilchumaly and other notables to receive and ally with Pizarro, whom he had notice of from his previous voyage to the Inca Empire in 1526. They signed their alliance in
Tumbes. Pizarro initiated his journey to the core of Inca Empire with the Cañaris to his side, concluding in
capture of Atahualpa in
Cajamarca, where Vilchumlay was probably present. Pizarro sent Vilchumlay with
Sebastián de Belalcázar to secure the port of
San Miguel de Piura, where he had left 40 soldiers to recover from wounds and illnesses while waiting for reinforcements. The conquistador was also in the need of contact them to prevent them from scattering and initiating unauthorized conquests. Meanwhile, Pizarro continued to Cusco, where he was received by the other main Cañari player,
Chilche. Thanks to the contacts established by Vilchumlay between Spaniards and Cañaris, Chilche joined Pizarro's circle as his advisor, bodyguard and champion. Vilchumlay also converted to Christianity adding Diego to his name. Diego Vilchumlay served in the Hispanic side during the conquest of the territories still held by former general of Atahualpa, like Lita and , and had an outstanding role during the revolt of
Manco Inca. Manco's lieutenant Quizu Yupanqui besieged
Lima in August 1536, to which Diego de Sandoval and Vilchumlay answered gathering a Cañari relief army. The news of their arrival drove Yupanqui to lift the siege. At some point, he also fought the
Saraguros of
Loja and served in the conquest of
Carumas. In 1554 he was among the Cañari captains recruited by Rodrigo de Salazar. He maintained a high status in the Spanish rule, even after the inevitable shifts brought by the new administration. He was rewarded for his service with the territories of El Pan, Toctesí and Hazmal, and his name is recorded in the foundation of
Cuenca, in the ancient Cañari center of
Tomebamba and close to his own domains. He died in 1666, being succeeded by his son Francisco Ymbay. ==References==
