Pg. 6 of the PDFHiram Wesley Evans, the Klan's Imperial Wizard, included the Louisiana Realm among the nation's fifteen strongest. One of the most sensational Klan acts of violence occurred in Morehouse Parish, located in northeastern Louisiana. Louisiana was a Southern state, but it presented a peculiar problem to the Klan in the South because of the cultural and religious differences of its population. North Louisiana was Protestant, Anglo-Saxon and bound to Victorian morality. South Louisiana was largely French, Catholic and less concerned with the stern morality of north Louisiana. But in south Louisiana there were Anglo-Saxon, Protestant "islands," which were sources of Klan strength, although hard to organize.If you're super interested, there are tons of pages to whatever book this is. However, I think this part on page 6 of the PDF largely answers our question!
