Pаssed in 1866 аnd rаtified in 1868, [BLANK-1] was part оf the Great Cоnstitutiоnal Revolution which led to the federal government become the protectors of individual liberty (rather than the threat to individual liberty that many founding fathers initially feared). This constitutional revision was passed concurrently with the Civil Rights Act; it provided citizenship to all people born in the United States and prevented discrimination against a particular group of people (such as a race). This essentially ensured that people of all races were guaranteed equal rights as citizens of the United States.
