Charles X sent a large fleet to execute the invasion of Algiers in 1830. The next year, his successor, Louis Philippe I, made a show of force against Portugal at the Battle of the Tagus, and in 1838 conducted another display of gunboat diplomacy, this time in Mexico at the Battle of Veracruz. Beginning in 1845, a five-year Anglo-French blockade of the Río de la Plata was imposed on Argentina over trade rights.
