Black History Month is celebrated every February and is a time set aside to learn about the accomplishments, culture, and contributions of African Americans.
Black History Month 2018 Theme
Since 1976, every American president has designated February as Black History Month and endorsed a specific theme.
The Black History Month 2018 theme, “African Americans in Times of War,” marks the 100th anniversary of the end of World War I and honors the roles that black Americans have played in warfare, from the American Revolution to the present day.
