Beginning in 1779, the
Spanish government began settling
Canary Islanders along Bayou Terre-aux-Boeufs and throughout the state of Louisiana to defend New Orleans and the territory against
Great Britain. This original settlement was known as the
Población de San Bernardo (St. Bernard Population) and was composed of smaller
establecimientos (establishments) or
puestos (posts). During the nineteenth and twentieth centuries, the seafood from Delacroix and other
Isleño fishing communities supplied many restaurants in New Orleans. Two years later, over one thousand people, mostly Isleños, perished from the
Spanish flu pandemic and were buried at a mass burial site in the St. Bernard Catholic Cemetery. The
Great Mississippi Flood of 1927 and dynamiting of the Mississippi River levee at Caernarvon left the community completely flooded. trappers from Delacroix drinking after the sale of animal pelts. Due in large measure to the isolation of Delacroix, many Isleño customs and traditions were preserved by community members into the later half of the twentieth century. Also of note, the former Prime Minister of Spain
Adolfo Suárez visited the community. In 1965,
Hurricane Betsy leveled much of the community once again. Following this, the visibility and practice of Isleño culture diminished substantially. In 2005,
Hurricane Katrina completely devastated the region and reshaped the community entirely. Only a small number of the original inhabitants of Delacroix returned to the community. == Geography ==
