Like other Southern states, the population of Louisiana is made up of numerous Protestant denominations, comprising 60% of the state's adult population. Protestants are concentrated in the northern and central parts of the state and in the northern tier of the
Florida Parishes. Because of French and Spanish heritage, whose descendants are Cajun and French Creole, and later Irish, Italian, Portuguese and German immigrants, there is also a large Roman Catholic population, particularly in the southern part of the state.

Since French Creoles were the first settlers, planters and leaders of the territory, they have traditionally been well represented in politics. For instance, most of the early governors were French Creole Catholics.
[18] Although nowadays constituting only a plurality but not a majority of Louisiana's population, Catholics have continued to be influential in state politics. As of 2008 both Senators and the Governor were Catholic. The high proportion and influence of the Catholic population makes Louisiana distinct among Southern states.
