How did Florida become a state of the United States?

Florida became a state of the United States on March 3, 1845. The process leading to statehood involved complex historical shifts, including periods of Spanish and British control, and conflicts with Native American groups like the Seminole. Following the cession of Florida to the United States in 1821, and after the suppression of Native American resistance, the territory was prepared for admission into the union. The state's history also includes secession in 1861 to join the Confederacy and subsequent occupation during Reconstruction.123
