Florida was readmitted to the Union in 1868 after the state granted civil rights to African Americans.
Explanation:
On January 10, 1861, Florida officially announced its secession from the Union, soon joining the Confederacy. The American Civil War would soon begin.
Florida, a major cotton producer, was one of the Confederate's main sources of income - the textile industries of several European countries such as France and England depended on American cotton, and the vast majority of this cotton was produced in Florida.
After the end of the war in June 1865, all states of the Confederacy, including Florida, were occupied by US forces. Florida, to be readmitted again as State of the Union, officially abolished slavery in 1866, and in 1868 the Florida government guaranteed civil rights to all citizens, thus being readmitted to the Union in the same year.
