He served as Governor of Montevideo between August 2, 1790, and February 11, 1797, and in 1792 was promoted to Field Marshal.

Then don Antonio Olaguer Feliú was named Viceroy of the Río de la Plata, a position he occupied between May 2, 1797, and May 14, 1799. During his mandate, he had to contend with the presence of British and Portuguese forces in the Río de la Plata region, as well as nascent revolutionary sentiment inspired by the recent French Revolution. He opened the port of Buenos Aires to foreign traffic in a bid to stimulate the commercial activities of the Viceroyalty, which had begun to suffer from the growing tensions between the European powers. On his return to Spain, he was named Secretary of War by Charles IV. He died in Madrid in 1813.
