On July 19 Tennessee became the first state to ratify the Fourteenth Amendment to the Constitution despite the opposition of President Andrew Johnson, a Tennessean himself, to the legislation. “We have fought the battle and won it,” Gov. William Gannaway Brownlow telegraphed the U.S. Senate.
The Fourteenth Amendment proposed that state legislatures be held to the same constitutional standards as the federal government, and thus it formally settled the question the war had answered: whether the United States was a single nation or a collection of states, each with its own laws. Persons born or naturalized in the United States (including former slaves) would be recognized as citizens of the United States and the states in which they lived, and all males of twenty-one years or more would be allowed to vote, with the exception of Indians who were not taxed.
