The culture of Washington, D.C. is reflected in its status as the capital of the United States and the presence of the federal government, its large Black population, and its role as the largest city in the Chesapeake Bay region. The presence of the U.S. federal government, in particular, has been instrumental in developing numerous cultural institutions throughout the city, such as museums and performing arts centers. The city's historic Black population has also helped drive cultural activities and artistic pursuits. During the early 20th century, for example, Washington's U Street Corridor became an important center for African American culture.
