For many US citizens, the Mexican-American War had demonstrated that conquering Latin America was both easy and the natural destiny of the United States. In the 1850s numerous adventurers tried their luck by mounting expeditions against Mexico and Central America, some hoping to perpetuate slavery by expanding the slave states. The most successful of these "filibusters" was William Walker, who gained control of Nicaragua in 1855 and held it for more than year before being driven out by Costa Rica and its allies.
