Juneteenth, officially Juneteenth National Independence Day, is a federal holiday in the United States. It is celebrated annually on June 19 to commemorate the ending of slavery in the United States. The holiday's name is a portmanteau of the words "June" and "nineteenth," as it was on June 19, 1865, when Major General Gordon Granger ordered the final enforcement of the Emancipation Proclamation in Texas at the end of the American Civil War.
