  • Explain the expansionist goals of advocates of slavery
  • Describe the filibuster expeditions undertaken during the antebellum era

Southern expansionists had spearheaded the drive to add more territory to the United States. They applauded the Louisiana Purchase and fervently supported Indian removal, the annexation of Texas, and the Mexican-American War. Drawing inspiration from the annexation of Texas, proslavery expansionists hoped to replicate that feat by bringing Cuba and other territories into the United States and thereby enlarging the American empire of slavery.

In the 1850s, the expansionist drive among white southerners intensified. Among southern imperialists, one way to push for the creation of an American empire of slavery was through the actions of filibusters—men who led unofficial military operations intended to seize land from foreign countries or foment revolution there. These unsanctioned military adventures were not part of the official foreign policy of the United States; American citizens simply formed themselves into private armies to forcefully annex new land without the government’s approval.

An 1818 federal law made it a crime to undertake such adventures, which was an indication of both the reality of efforts at expansion through these illegal expeditions and the government’s effort to create a U.S. foreign policy. Nonetheless, Americans continued to filibuster throughout the nineteenth century. In 1819, an expedition of two hundred Americans invaded Spanish Texas, intent on creating a republic modeled on the United States, only to be driven out by Spanish forces. Using force, taking action, and asserting white supremacy in these militaristic drives were seen by many as an ideal of American male vigor. President Jackson epitomized this military prowess as an officer in the Tennessee militia, where earlier in the century he had played a leading role in ending the Creek War and driving Indian peoples out of Alabama and Georgia. His reputation helped him to win the presidency in 1828 and again in 1832.

Filibustering plots picked up pace in the 1850s as the drive for expansion continued. Slaveholders looked south to the Caribbean, Mexico, and Central America, hoping to add new slave states. Spanish Cuba became the objective of many American slaveholders in the 1850s, as debate over the island dominated the national conversation. Many who urged its annexation believed Cuba had to be made part of the United States to prevent it from going the route of Haiti, with black slaves overthrowing their masters and creating another black republic, a prospect horrifying to many in the United States. Americans also feared that the British, who had an interest in the sugar island, would make the first move and snatch Cuba from the United States. Since Britain had outlawed slavery in its colonies in 1833, blacks on the island of Cuba would then be free.

Narisco López, a Cuban who wanted to end Spanish control of the island, gained American support. He tried five times to take the island, with his last effort occurring in the summer of 1851 when he led an armed group from New Orleans. Thousands came out to cheer his small force as they set off to wrest Cuba from the Spanish. Unfortunately for López and his supporters, however, the effort to take Cuba did not produce the hoped-for spontaneous uprising of the Cuban people. Spanish authorities in Cuba captured and executed López and the American filibusters.
