President Abraham Lincoln announced the preliminary Emancipation Proclamation, stating it would take effect on January 1, 1863 and promise freedom to enslaved people in rebelling Confederate areas. This set the legal and political framework that Juneteenth later commemorates—while also foreshadowing uneven enforcement across the South.

The final Emancipation Proclamation went into effect, declaring freedom for enslaved people in Confederate states in rebellion (with key limits in places under Union control or loyal border states). In remote Texas, enforcement remained slow and inconsistent, which is a core reason June 19, 1865 became so significant.
