The weakness of the federal government
Congressional victory over Johnson
Congress rejected Johnson's plans and passed a Civil Rights Act which overrode Black Codes. Johnson vetoed this but Congress ensured it came into law in April 1866. It became the Fourteenth Amendment , giving all AA born in USA citizenship and full rights.
November 1866 mid-term congressional elections- Republicans gained a two-thirds majority in both Houses. Johnson was impeached but survived by one vote. 1868 election- easily defeated by Republican former army general Ulysses S. Grant.
