Did you know that the first black members of the US House of Representatives were all Republicans?

The first African Americans to serve in the Congress were Republicans elected during the Reconstruction Era. After the 13th and 14th Amendments granted freedom and citizenship to enslaved people, freedmen gained political representation in the Southern United States for the first time.[4][5][6] In response to the growing numbers of black statesmen and politicians, white Democrats turned to violence and intimidation to regain their political power.[7]
