Juneteenth, observed annually on June 19, is a federal and New York state holiday that commemorates the end of slavery in the United States.

It marks the day in 1865 when Union troops arrived in Galveston, Texas, and informed enslaved Black Americans of their freedom — more than two years after President Abraham Lincoln issued the Emancipation Proclamation.

The holiday has grown in prominence in recent years, becoming a federal holiday in 2021 and a New York State holiday in 2020. It is celebrated across the country with festivals, marches, and educational events honoring Black history and culture.
