12/18 Abolition of slavery

When: 1865

Who：Abraham Lincoln

What：The 13th Amendment was formally adopted into the U.S. Constitution, ensuring that “neither slavery nor involuntary servitude… shall exist within the United States, or any place subject to their jurisdiction.”

Why significant：On this day, slavery was abolished in the U.S. - 246 years after the first shipload of captive Africans landed at Jamestown, Virginia, and were bought as slaves.

Slavery’s legacy and efforts to overcome it remained a central issue in U.S. politics, particularly during the post-Civil War Reconstruction era and the African American civil rights movement of the 1950s and ’60s. Though the amendment formally abolished slavery throughout the United States, factors such as Black Codes, white supremacist violence, and selective enforcement of statutes continued to subject some black Americans to involuntary labor, particularly in the South. In contrast to the other Reconstruction Amendments, the Thirteenth Amendment was rarely cited in later case law, but has been used to strike down peonage and some race-based discrimination.
