Northern Mariana Islands Liberation Day, observed in the Commonwealth of the Northern Mariana Islands on July 4, commemorates the release of civilians held in Camp Susupe on Saipan in 1946. This day coincides with the United States Independence Day, as the Northern Mariana Islands is an incorporated territory of the U.S. The holiday is marked by remembrance ceremonies, colorful parades, concerts, and parties that honor those who suffered during World War II while celebrating the islands' history and culture. The origins of the day trace back to the aftermath of World War II, specifically the liberation of 2,230 Chamorros and 800 Carolinians from the camp. Notable events during the celebration include various community activities that reflect the local traditions and heritage.
