Based on source 3 and source 4 , why did both Acadian and Haitan immigrants came to Louisiana?

Louisiana was a city under Spanish control in the mid to late 18th century and it was more tied to Caribbean culture and society than it was to the United States.  The rules regarding slaves and free blacks were different in Louisiana than in the United States. In the Spanish regime, black slaves could purchase their freedom.

Explanation:

In the 18th century, the British evicted the Acadians from parts of Eastern Canada because they would not take an oath of allegiance to the King of England. In the 1760s the Acadians were compelled to emigrate and one area they left to was Lousiana. At the time the Spanish controlled Louisiana and French settlers were preferred because they were also largely Catholic.  In Europe, there was also the onset of the French Revolution and this led many Frenchmen to flee France for the colonies like Haiti while they tried to escape the turmoil of the revolution. However the slaves in Haiti were also pushing to change the regime and strong slave uprisings began.  The danger was so great in Haiti that the colonists and many black Haitians fled Haiti for Louisiana.
