Ignacio Álvarez Thomas

Who was Ignacio Álvarez Thomas?

José Ignacio Álvarez Thomas was a South American military commander and politician of the early 19th century.

Álvarez Thomas was born in Arequipa, Peru, and his family lived for some time in Lima. When his father, who was in Spanish service, was called back to Madrid in 1797, they travelled via Buenos Aires. The family stayed there while his father continued the voyage alone, and Álvarez joined the army in 1799. Subsequently, he got heavily involved in the independence war in Argentina.

In the war against the British in 1806/07, he was wounded and captured, and released only after the withdrawal of the British troops. Under Carlos María de Alvear, he fought as a Colonel at Montevideo, where he was awarded a medal. However, soon after he openly opposed the politics of de Alvear's government, and his insurrection caused the resignation of the latter and resulted in a new election of a Supreme Director in the Constituting General Assembly, where he was designated interim Supreme Director from April 20, 1815 to April 16, 1816 in place of the elected José Rondeau, who was absent on a military campaign in Peru. Álvarez was sworn in on May 6 but had to resign a year later after some military failures. When the Constituting General Assembly was dissolved in 1820, he was, as a still-influential member of the former leadership, sent to prison, but released after 19 days. Subsequently, his political influence was greatly diminished.
