There have been a variety of ethnic groups in Baltimore, Maryland and its surrounding area for 12,000 years. Prior to European colonization, various Native American nations have lived in the Baltimore area for nearly 3 millennia, with the earliest known Native inhabitants dating to the 10th millennium BCE. Following Baltimore's foundation as a subdivision of the Province of Maryland by British colonial authorities in 1661, the city became home to numerous European settlers and immigrants and their African slaves. Since the first English settlers arrived, substantial immigration from all over Europe, the presence of a deeply rooted community of free black people that was the largest in the pre-Civil War United States, out-migration of African-Americans from the Deep South, out-migration of White Southerners from Appalachia, out-migration of Native Americans from the Southeast such as the Lumbee and the Cherokee, and new waves of more recent immigrants from Latin America, the Caribbean, Asia and Africa have added layers of complexity to the workforce and culture of Baltimore, as well as the religious and ethnic fabric of the city. Baltimore's culture has been described as "the blending of Southern culture and [African-American] migration, Northern industry, and the influx of European immigrants—first mixing at the port and its neighborhoods...Baltimore’s character, it’s uniqueness, the dialect, all of it, is a kind of amalgamation of these very different things coming together—with a little Appalachia thrown in...It’s all threaded through these neighborhoods", according to the American studies academic Mary Rizzo.[1]
