The name of Biloxi in French was Bilocci, a transliteration of the term for the local Native American tribe in their language. La Louisiane was separated from Spanish Florida at the Perdido River near Pensacola (this was founded by the Spanish 1559 and again in 1698). The settlement was under the direction of Pierre Le Moyne d'Iberville. In 1699, French colonists formed the first permanent, European settlement in French Louisiana, at Fort Maurepas, now in Ocean Springs, Mississippi, and referred to as 'Old Biloxi'.
