Historical Map of North America & the Caribbean

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.

Main Events

Third Seminole War

Seminole retaliate against settler encroachment in southwest Florida, United States of America, massacring an army patrol near Fort Myers and mounting raids on settlers throughout the region; eventually army reinforcements force them to surrender and most of the remaining Seminole are relocated to Indian Territory (Oklahoma)

Filibuster War

Allied Armies of Central America, led by Republic of Costa Rica, invade the Republic of Nicaragua, which has fallen under the control of William Walker and his filibusters; Walker eventually surrenders to Captain Charles Davis of the US Navy, departing the country with 16 officers and promising never to return to Central America

Dred Scott case

US Supreme Court holds that African Americans cannot be American citizens and therefore cannot sue in federal court, and that the federal government has no power to regulate slavery in the federal territories acquired after the creation of the United States of America

Henry Crabb's Sonora expedition

Former California State Senator Henry Crabb and his band of filibusters intervene in Sonora, Mexican Republic, after an alleged deal with local governor Ignacio Pesqueira falls through; Crabb defeats local forces near Caborca, but is captured and executed a few days later when Mexican reinforcements arrive
