Governor of Chile
An ambitious man and badly advised by his relatives and friends, his government was characterized by continuous difficulties with the natives and the
Concepción. In the
Parliament of Boroa (1651) he reached a peace accord with the indigenous peoples that was broken within two years.
The followers of the Governor went into
Mapuche territory with the aim to profit from the war. The failure of the successive expeditions and the indigenous revolt of 1655, motivated the vecinos of
Concepcion to declare the deposition of Acuña to the shouts of ” The king lives! The bad governor dies!”, an action that was not accepted by the
Audiencia and the Junta de Guerra, that reestablished Acuña in control.
Given these circumstances, the
Viceroy of Peru sent for him to appear before him. Acuña did not accept the order. A new governor
Pedro Porter Casanate, was appointed, and his first mission was to force the return of Acuña to
Lima, where he would die shortly afterward.
