Who was the first African American Governor in the U.S.? The answer is not who you think.

–Pinchbeck was the first African American Gov. He wasn’t elected. He was the son of a former slave, and slave master who lived together as husband and wife.

In 1872, the Louisiana legislature filed impeachment charges against the incumbent Republican governor, Henry Clay Warmoth due to disputes over certifying returns of the disputed gubernatorial election, in which both Democrat John McEnery and Republican William Kellogg claimed victory. Trying to support a centrist fusion government at a time of divisions among Republicans, Warmoth had supported his appointed return board, which certified McEnery as winner. Republicans opposed this outcome, and appointed their own returns board, which certified Kellogg. The election had been marked by violence and fraud. State law required that Warmoth step aside until his impeachment case was tried. Pinchback took the oath as acting governor on December 9, 1872, and served for about six weeks until the end of Warmoth’s term. Warmoth was not convicted, and the charges were eventually dropped by the legislature.
