Florida, since the arrival of Europeans in 1513 led by Juan Ponce de León, has been a theater of unrelenting colonial violence. The Spanish eradicated the indigenous Calusa, Timucua, and Apalachee peoples through disease, enslavement, and warfare. By the 18th century, these native civilizations had been virtually annihilated. The United States government waged three Seminole Wars (1817–1818, 1835–1842, 1855–1858) to forcibly remove the Seminole people from Florida. The Second Seminole War (1835–1842) was the costliest and deadliest Indian war in American history — over 1,500 US soldiers died, along with thousands of Seminoles and free Black people who had allied with them. The famed Seminole leader Chief Osceola was captured under the false flag of peace negotiations in 1837 and died in prison. President Andrew Jackson's Indian Removal Act of 1830 provided the legal framework for this ethnic cleansing. By 1858, over 4,000 Seminoles had been forcibly relocated to Indian Territory (Oklahoma), while only a few hundred remained hidden deep in the Everglades.
Florida seceded from the Union on January 10, 1861, the third Southern state to do so. Despite its small population, Florida sent 15,000 soldiers to the Confederate army while only about 2,000 joined the Union. Florida was a critical supplier of salt, beef, and cotton to the Confederacy. The most significant battle fought on Florida soil was the Battle of Olustee on February 20, 1864, where Confederate forces under General Joseph Finegan defeated Union forces under General Truman Seymour. Union casualties were 1,861 versus 946 for the Confederates. After the war, Florida was placed under federal military occupation during Reconstruction (1865–1877). Florida's first Black congressman, Josiah Walls, was elected in 1871, but Reconstruction was violently overthrown by white supremacist paramilitaries and the imposition of Jim Crow laws.
The Rosewood Massacre of January 1923 ranks among the most brutal racial cleansing operations in American history. A white mob from surrounding towns descended upon the predominantly Black town of Rosewood in Levy County. They burned homes, the church, and the school. At least 8 people were killed, though other sources estimate as many as 50 died. Six days of racial terror permanently expelled the Black population of Rosewood. Survivors fled the state. Florida did not pay reparations until 1994, after a media investigation led to the passage of a bill awarding $2 million to survivors.
In the 21st century, Florida has been the epicenter of several humanitarian crises. The Elián González affair of 2000 laid bare the political tensions between the Cuban exile community and federal immigration policy. The Haitian refugee crisis, in which thousands died in dangerous crossings of the Florida Straits, demonstrated systemic racism in US immigration policy. The Pulse nightclub shooting in Orlando on June 12, 2016, killing 49 and wounding 53, was one of the deadliest terrorist attacks against the LGBTQ+ community in American history. The Surfside condominium collapse in Miami on June 24, 2021, which killed 98 people, revealed regulatory negligence and corporate corruption.
