Black History Month

Black History Month, also known as African-American History Month in America, is an annual observance in the United States, Canada, and the United Kingdom for remembrance of important people and events in the history of the African diaspora. It is celebrated annually in the United States and Canada in February, and the United Kingdom in October.

History
The precursor to Black History Month was created in 1926 in the United States, when historian Carter G. Woodson and the Association for the Study of Negro Life and History announced the second week of February to be "Negro History Week." This week was chosen because it coincided with the birthday of Abraham Lincoln on February 12 and of Frederick Douglass on February 14, both of which dates Black communities had celebrated together since the late 19th century.
From the event's initial phase, primary emphasis was placed on encouraging the coordinated teaching of the history of American blacks in the nation's public schools
The expansion of Black History Week to Black History Month was first proposed by the leaders of the Black United Students at Kent State University in February 1969. The first celebration of the Black History Month took place at Kent State one year later, in February 1970.
In 1976 as part of the United States Bicentennial, the informal expansion of Negro History Week to Black History Month was officially recognized by the U.S. government. President Gerald Ford spoke in regards to this, urging Americans to "seize the opportunity to honor the too-often neglected accomplishments of black Americans in every area of endeavor throughout our history.
