All of them played a major part in the capture (1531–38) and rule of Peru. However, after the death of legal governor Francisco, their legitimate claims were practically forfeit. Juan had died during the ten month-long siege of Cuzco and Hernando was sent back as envoy to Spain and imprisoned in 1540, after accusations of corruption and tax evasion pointed towards the Pizarro administration. After Francisco's assassination in 1541, power was usurped by Cristóbal Vaca de Castro as new governor of "New Castile". In 1544 the king of Spain, who had also granted Francisco governorship in 1528, sent his own envoy Blasco Núñez Vela, as viceroy of Peru. Blasco imprisoned Castro but was the very same year detained and later killed on the behalf of Gonzalo Pizarro, who gathered his supporters and seized much of Peru. When Blasco's successor, Pedro de la Gasca defeated and had Gonzalo executed in 1548, the reign of the Pizarro brothers had definitely passed.
