On June 19, 1865, two and a half years after President Abraham Lincoln’s historic Emancipation Proclamation, U.S. Maj. Gen. Gordon Granger issued General Order No. 3, which informed the people of Texas that all enslaved people were now free. They were the last group of Americans to be informed that all formerly enslaved persons were now free.

To understand Juneteenth’s significance, one must understand how geography, military occupation, timing, and the resilience of a proud people solidified June 19, 1865, as the date that symbolizes freedom for African Americans. The National Archives is the home of General Order No. 3 (National Archives Identifier 182778372), the document whose date of issue gave this celebration and holiday its name.

Double Take: Finding Posters within Photos

For our staff, it is always a thrill to find something new in the millions of the digitized photographs, especially if it connects other records in our holdings. Once Daniel Dancis, a textual records archivist, started to notice some familiar WWII posters within WWII photographs in our holdings, he started to see them everywhere. He shares these finds and looks at the messaging in these meta moments in history in the Unwritten Record blog.
