National Constitution Center: Juneteenth Information Blog and PodcastThe anniversary of an 1865 announcement by a Union military official in Texas has grown over the years into a celebration of emancipation - the end of slavery in the United States.In the Congressional Research Service’s recent guide to the Juneteenth holiday, the service says that unofficial Juneteenth celebrations started in Texas’s African-American community the following year. “Texans celebrated [the Juneteenth anniversary] beginning in 1866, with community-centric events, such as parades, cookouts, prayer gatherings, historical and cultural readings, and musical performances,” the CRS recounts.
Over time, the Juneteenth holiday was celebrated outside of Texas in the South and other parts of the country. A 1949 reference in the journal American Speech indicated that Juneteenth was the day African-Americans “in the South commemorate the freedom of their race from slavery.”
As for the word Juneteenth, it is an example of a portmanteau or a word that combines the meaning of several words.
