On April 29, 1784, shortly after leaving his post as viceroy of Peru, the Basque soldier and politician Agustín de Jáuregui y Aldecoa died in an accident in Lima.
Born in Lekaroz in the Baztan Valley of Navarre in 1711, he entered into the military at the age of twenty-five and crossed the Atlantic to , fighting at the British siege of Cartagena de las Indias in 1740, and rising to the rank of lieutenant general. Later, he also saw active service against the British in Cuba and Honduras and in Spain’s siege of the Portuguese city of Almeida in 1762.
In 1772 he was appointed governor of what was termed at the time the Captaincy General of Chile. While governor, he promulgated a series of administrative reforms, including establishing a postal service and overseeing the first census there. He also carried out reforms related to public order, reorganized the tax-collection system, and created a militia to serve as a kind of rural police force as well as a reserve military unit.
In 1780 he was appointed viceroy of the Viceroyalty of Peru. Almost immediately, he had to deal with the Túpac Amaru rebellion of 1780, an uprising of native and mestizo people against the so-called Bourbon reforms in Peru: changes designed to strengthen Spanish royal power there by giving more power to royal officials. Jáuregui succeeded in defeating the leader of the revolt, Túpac Amaru II (José Gabriel Condorcanqui) in 1781, and he was subsequently executed. Other rebel leaders were killed or executed in the period 1781 to 1783.
Shortly after leaving his post in April 1784, Jáuregui died in an accident in Lima. There were rumors that he had been poisoned beforehand as revenge for crushing the Túpac Amaru rebellion so brutally, but these remain unsubstantiated.
