Osceola leads his Seminole warriors in Florida into the Second Seminole War against the United States Army.

Osceola, named Billy Powell at birth, was an influential leader of the Seminole people in Florida. His mother was Muscogee, and his great-grandfather was a Scotsman, James McQueen. He was reared by his mother in the Creek (Muscogee) tradition. When he was a child, they migrated to Florida with other Red Stick refugees, led by a relative, Peter McQueen, after their group's defeat in 1814 in the Creek Wars. There they became part of what was known as the Seminole people.

The Seminole are a Native American people who developed in Florida in the 18th century. Today, they live in Oklahoma and Florida, and comprise three federally recognized tribes: the Seminole Nation of Oklahoma, the Seminole Tribe of Florida, and the Miccosukee Tribe of Indians of Florida, as well as independent groups. The Seminole people emerged in a process of ethnogenesis from various Native American groups who settled in Spanish Florida beginning in the early 1700s, most significantly northern Muscogee Creeks from what are now Georgia and Alabama.
