In 1807, Assumption became the eighth parish of the Orleans Territory. Its history is rooted in its waterways and its large expanse of fertile soils ideal for farming. Settled in the middle 18th century by French and Spanish settlers, the area retains strong cultural ties to its past with conversational French still common among residents. Assumption was also a final destination for many of the French Acadians exiled from Nova Scotia between 1755 and 1764.

After the Confederacy forced the surrender of Fort Sumter, South Carolina, in 1861, the Assumption Parish Police Jury appropriated $1,000 to provide uniforms for military volunteers against the Union. By contrast, Lafayette Parish contributed $6,000. Plaquemines Parish approved a gift of $10 to $15 per month for needy volunteer families.
