African American history is the portion of American history that specifically discusses the African American or Black American ethnic group in the United States. Most African Americans are the descendants of captive Africans held in the United States from 1619 to 1865. Blacks from the Caribbean whose ancestors immigrated, or who immigrated to the U.S., also traditionally have been considered African American, as they share a common history of predominantly West African or Central African roots, the Middle Passage and slavery.
It is these peoples, who in the past were referred to and self-identified collectively as the American Negro, who now generally consider themselves African Americans. It is these peoples whose history is celebrated and highlighted annually in the United States during February, designated as Black History Month, and it is their history that is the focus of this article.
Others who sometimes are referred to as African Americans, and who may self-identify as such in US government censuses, include relatively recent Black immigrants from Africa, South America and elsewhere who self-identify as being of African descent.
