Following the end of the Civil War, in May of 1866 Congress passed a law removing these rights from supporters of the Confederacy. Gradually, states that had seceeded were let back into the union. Texas was readmitted on March, 30, 1870, Mississippi was readmitted February 23, 1870, and Virginia on January 26, 1870. Georgia became the last Confederate state to be readmitted into the Union on July 15, 1870. All members for the House of Representatives and Senate were seated from the 10 Confederate states who seceded.
To ease tensions, Grant signed the Amnesty Act. It gave amnesty to former Confederates. This act allowed most former Confederates, to hold elected public office. Only 500 former Confederates remained unpardoned and therefore forbidden to hold elected public office. The Act affected over 150,000 former Confederate troops who had taken part in the American Civil War.
