The place was named in honour of the Battle of Trocadero, in which the fortified Isla del Trocadero, in southern Spain, was captured by French forces led by the Duc d'Angoulême, son of the future King of France, Charles X, on 31 August 1823. France had intervened on behalf of King Ferdinand VII of Spain, whose rule was contested by a liberal rebellion. After the battle, the autocratic Spanish Bourbon Ferdinand VII was restored to the throne of Spain.
