Dade Battlefield Historic State Park is located at the site of the battle that started The Second Seminole War. Nearly a decade after the Treaty of Moultrie Creek (1824), the U.S. Army was attempting to forcibly remove the Seminoles from their homeland to "Indian Territory", which would later become Oklahoma. Of course tensions would flare and war broke out, and this was the site of the first battle.
A reenactment of the battle is held at the park each year on the first weekend after Christmas, as that is generally the closest date to the anniversary.
