Jean Ribault was a French naval officer, navigator, and a colonizer of what would become the southeastern United States. He was a major figure in the French attempts to colonize Florida. A Huguenot and officer under Admiral Gaspard de Coligny, Ribault led an expedition to the New World in 1562 that founded the outpost of Charlesfort on Parris Island in present-day South Carolina. Two years later, he took over command of the French colony of Fort Caroline in what is now Jacksonville, Florida. He and many of his followers died at the hands of Spanish soldiers during the Massacre at Matanzas Inlet, near St. Augustine.

Gaspard de Coligny, seigneur de Châtillon, was a French nobleman, Admiral of France, and Huguenot leader during the French Wars of Religion. He served under kings Francis I and Henry II during the Italian Wars, attaining great prominence both due to his military skill and his relationship with his uncle, the king's favourite Anne de Montmorency. During the reign of Francis II he converted to Protestantism, becoming a leading noble advocate for the Reformation during the early reign of Charles IX.
