Juneteenth — which in 2020 became a state and public holiday in New Jersey — “has never been explicitly taught in American history,” writes Dr. Lisa Thomas for the Share My Lesson section of AFT’s website.

“June 19, 1865, is the day all people living in the United States, including the formerly enslaved, were officially granted freedom,” Thomas writes. “The celebration is a recognition of that freedom. … Progress has been made on awareness of Juneteenth, but there is still much more work to be done.”
