Ever since Washington was carved from two slaveholding states in 1791, it has been a special place for black Americans. Lincoln freed the slaves in Washington about nine months before the Emancipation Proclamation, prompting blacks from the region to flock here. It was the birthplace of Duke Ellington and home to other artists like Zora Neale Hurston and Sterling Allen Brown, who later fueled the Harlem Renaissance. By 1957, blacks had become the majority of the city’s residents, exceeding numbers in any major city in the United States. Ever since Walter E. Washington was appointed mayor by Lyndon B. Johnson in 1967, the city has been led by black politicians and shaped by black institutions. This has fostered a sense of black privilege, swagger and, yes, the hubris that comes with leadership.
