At times, it was easy to forget that "Harlem" was originally the Dutch name "Harrlem", that the community it described had been founded by people from Holland; and that for most cites three centuries—it was first settled in the sixteen hundred it had been occupied by White New Yorkers. "Harlem" became synonymous with Black life and Black style in Manhattan. Blacks living there

C. Immigrants from the South, the Caribbean, and parts of Africa settled in Harlem as a result of the First World War.
D. Some black immigrants came to live in Harlem because it was in New York city.
