On January 1, 1863, in the middle of the Civil War, President Abraham Lincoln's Emancipation Proclamation took effect. It declared that enslaved people in the states fighting against the Union were free. But a proclamation is only words on paper unless someone can enforce it, and the Union army could enforce it only in places it controlled.

Texas was far from most of the fighting, and Union troops held very little of it. Some slaveholders from other Southern states even moved the people they enslaved to Texas to keep them away from the advancing Union army. For more than two years after the Proclamation, slavery continued in Texas much as before.

The main Confederate army surrendered in April 1865, but news and soldiers moved slowly. On June 19, 1865, Union General Gordon Granger arrived in Galveston and issued General Order No. 3. It announced that, in keeping with the Proclamation, all enslaved people in Texas were free. Even then, freedom did not arrive everywhere at once. Some enslavers delayed telling the people they held, and some waited until the harvest was finished.

Formerly enslaved Texans began celebrating June 19 the following year. They gathered for prayer, food, music, and readings of the order. In some places, Black communities raised money to buy land where they could hold the celebration freely. Emancipation Park in Houston began this way. The day became known as Juneteenth, a blend of "June" and "nineteenth."

Slavery did not end everywhere in the United States in 1865 because of a Texas order. That happened when the Thirteenth Amendment to the Constitution was ratified in December 1865. But Juneteenth became the date that many Americans chose to remember the end of slavery. In 1980, Texas became the first state to make Juneteenth an official state holiday. In 2021, it became a federal holiday, celebrated across the country.

Today, Juneteenth celebrations include parades, family reunions, and community events. For many families, it is also a day to remember that freedom, once declared, still had to be carried, announced, and defended before it became real.
