African-American officeholders in the United States, 1789–1866
The United States has had five African American elected officeholders prior to 1867. After Congress passed the First Military Reconstruction Act of 1867 and ratified the Fifteenth Amendment to the United States Constitution in 1870, African Americans began to be elected or appointed to national, state, county and local offices throughout the United States.
