Black History Month is an annually observed commemorative month originating in the United States, where it is also known as African-American History Month and was formerly known as Negro History Month before 1976.[4] It began as a way of remembering important people and events in the history of the African diaspora, initially lasting a week before becoming a month-long observation since 1970.[5] It is celebrated in February in the United States[6] and Canada,[7] where it has received official recognition from governments, but more recently has also been celebrated in Ireland and the United Kingdom where it is observed in October.[8][9]
