The early history of the parish dates to the period of the Spanish occupation of Louisiana, after France had ceded this territory following its defeat by Great Britain in the Seven Years' War. In 1797, Jose M. Mora was granted a large tract of land between the Rio Hondo (now Calcasieu River) and the Sabine River, known for years as the "Neutral Strip" between Louisiana and Texas. The area became a refuge for outlaws and filibusters from Carolina, Georgia, and Mississippi of the United States, which had recently gained independence from Great Britain.
