New Orleans, despite being in the south and having legalized slavery, had a lot in common with the northern industrialized port cities that were attractive to immigrants. Civil War era New Orleans had a large and diverse immigrant population (though Irish and Germans were the two largest groups), not unlike northern cities.New Orleans was originally French and had a large Catholic population to begin with, so that might have been part of the reason Croats went there. In general, immigrants did not venture into the rural south. There was already a supply of cheap labor and it wasn't a good place to obtain marginal farm land, as most was taken in large estates.
Immigrants in the north and south generally fought for the local side and it didn't have much to do with how they were treated.
