On June 19, 1865, two months after the Civil War ended and two and a half years after the Emancipation Proclamation, Union Army General Gordon Granger rode into Galveston, Texas to announce that "all slaves are free." And that "an absolute equality of personal rights and rights of property between former masters and slaves" should persist. Henceforth, June 19th (Juneteenth) is designated as a day of celebration for the end of slavery!
In June 2020, Juneteenth is officially recognized as a state holiday in Massachusetts. The library will be closed on Saturday 6/19/2021 and the following Monday (6/21/2021) to observe it.
