He is best known for founding the first permanent French settlement in Louisiana and for his role in the early exploration of the Mississippi River region. D'Iberville was a key figure in expanding French influence in North America during the late 17th century. Throughout his career, d'Iberville led several successful military campaigns against the British and Spanish in North America. He established Fort Maurepas in 1699, which served as a base for further exploration and settlement.
