The Emancipation Proclamation took effect in 1863 and applied to areas in rebellion. The 13th Amendment, ratified on December 6, 1865, abolished slavery nationwide under the Constitution, subject to its punishment-for-crime exception.
Other dates matter too. Juneteenth commemorates the announcement of emancipation in Galveston, Texas, on June 19, 1865. No single date describes every person's experience of enslavement, emancipation, or the systems of forced labor that followed.
