The Slave Power, or Slavocracy, referred to the perceived political power held by American slaveholders in the federal government of the United States during the Antebellum period.^[1] Antislavery campaigners charged that this small group of wealthy slaveholders had seized political control of their states and were trying to take over the federal government illegitimately to expand and protect slavery. The claim was later used by the Republican Party that formed in 1854–55 to oppose the expansion of slavery.

The term was popularized by antislavery writers including Frederick Douglass, John Gorham Palfrey, Josiah Quincy III, Horace Bushnell, James Shepherd Pike, and Horace Greeley. Politicians who emphasized the theme included John Quincy Adams, Henry Wilson and William Pitt Fessenden.
