Calcasieu Parish, Louisiana: History
=== Early history ===
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.
The territory was disputed for years between Spain and the United States after France had ceded Louisiana to the American government as part of the Louisiana Purchase of 1803. It was definitively acquired by the United States from Spain with the Adams-Onis Treaty in 1819. The treaty was formally ratified on February 22, 1821. By an act of Congress, approved on March 3, 1823, this strip of land was attached to the district of the Louisiana Territory south of the Red River.
Early settlers to the area included the LeBleu, Sallier, Ryan, Perkin, Hodges, Bilbo, Deviers, and Henderson families. Acadian settlers, from the eastern parishes of Louisiana, also migrated to this area. Of French descent and exiled by the British from Acadia (eastern Canada), many of these refugees had settled in Louisiana. The parish had a diverse ethnic mix of French and Spanish Creoles, Acadians, Anglo-Americans, Enslaved African Americans, Free African Americans, and Indians. Data compiled from historical volumes of the US Center of Population and Housing indicate that in 1850, 240 of 3914 Parish residents were "Free Men of Color". By 1860 that number had risen to 305 of 5928. The 1860 U.S. census of Louisiana counts 1171 Slaves among Calcasieu Parish residents. …
