Black History Month is celebrated every February and is a time set aside to learn about the accomplishments, culture, and contributions of African Americans.

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.
