Spanish Louisiana was a territory in North America that existed from 1762 to 1803. It was acquired by Spain after the French and Indian War and included parts of present-day Louisiana, Arkansas, Mississippi, and Alabama. The capital was New Orleans, a vital port city that facilitated trade and cultural exchange. During its time under Spanish rule, the region saw significant changes, including the introduction of Spanish law and governance. The population included a mix of French, Spanish, and African cultures, which influenced the local customs, cuisine, and language. In 1803, the territory was returned to France and subsequently sold to the United States in the Louisiana Purchase.
