There is no specific International Day in Black history. However, Black History Month is celebrated in various countries around the world during the month of February to recognize and honor the achievements, contributions, and history of Black individuals and communities. The origins of Black History Month can be traced back to the United States, where it was first established as "Negro History Week" in 1926 by historian Carter G. Woodson. Over time, it expanded into a month-long celebration and has since been adopted by other countries to raise awareness of Black history and promote understanding and equality.
