Juan Manuel de Rosas was the Governor of Buenos Aires Province from 1829 to 1832 and 1835 to 1852. He's also famous for defeating an Anglo-French invasion during the Battle of Vuelta de Obligado in 1845. At the time the country fought many civil wars between Federals and Unitarians, Rosas being a federal leader. He was ousted from power by Justo José de Urquiza, governor of the Entre Ríos Province, at the battle of Caseros. Defeated, he was rescued by a British warship and moved to Southampton, where he stayed the rest of his life. He died on March 14, 1877, and he was buried at the Southampton Old Cemetery. Fearing pro-Rosas demonstrations, the Argentine government forbid any commemoration in his honour, and made instead a mass for the people that died during Rosas's government.
