Juneteenth, a combination of "June" and "nineteenth," is considered the longest-running African American holiday. It commemorates the date when hundreds of thousands of enslaved men and women in Texas finally learned they had been freed in 1865.

Below is what you need to know about the date:

June 19, 1865 marks the day when it was announced that slaves were freed in Galveston, Texas, following the end of the Civil War. However, that announcement came more than two and a half years after President Abraham Lincoln had issued the Emancipation Proclamation. Juneteenth honors the end to slavery in the United States and is considered the longest-running African American holiday.

In 2021, Congress voted to make Juneteenth the 12th federal holiday. Before the vote, it was already a state holiday in New York and New Jersey.

In 2020, there was a renewed interest in the day that celebrates freedom, following nationwide protests over police brutality and the deaths of George Floyd, Breonna Taylor, Ahmaud Arbery and other Black Americans.
