National Freedom Day is celebrated annually on February 1st in the United States. It commemorates the signing of a joint resolution by President Abraham Lincoln and the U.S. Congress that later became the 13th Amendment to the U.S. Constitution. The 13th Amendment abolished slavery in the United States and was officially ratified on December 6, 1865.

The observance of National Freedom Day serves as a reminder of the long struggle for freedom and equality that African Americans have faced in the country's history. It is a day to honor the contributions and achievements of Black Americans and to reflect on the ongoing fight for civil rights and social justice.

National Freedom Day was first celebrated on February 1, 1942, as a result of the efforts of Major Richard Robert Wright Sr., a former slave and civil rights activist. Wright believed that the abolition of slavery was a crucial step towards achieving equality and freedom for all Americans. Today, National Freedom Day serves as an opportunity to promote unity, diversity, and understanding among all people in the United States.
