July 4th most think of the founding of our country when the thirteen colonies fought Britain and became an independent country. Florida at that time were two colonies under British control that chose to remain loyal despite the invitation to join the Patriots’ fight for independence. You can read more about that in this blog post.
The Republican Party, whose nominee was Ulysses S. Grant, held a Presidential campaign in Tallahassee. “The [Tallahassee] Floridian reported that the Republican Party held a Presidential campaign rally to celebrate this auspicious occasion and that the crowds from all over the state, particularly newly enfranchised freedmen, made up ‘Probably the largest crowd here, ever before at any time.'” source.
Grant due to his popularity in the North for ending the Civil War with the surrender of General Robert E. Lee at Appomattox and his popularity in South among the newly enfranchised slaves won the election against Democratic nominee Horatio Seymour. He won Florida which gave him three electoral votes and won him the Presidency. Virginia, Mississippi, and Texas were not reinstated into the Union and were therefore unable to participate in the Presidential election.
