How did black christianity differ from white christianity in the old south? how did black christianity in the south differ from black christianity in the north?

The First Great Awakening was the result of the Civil War which sprang up Methodist and Southern Baptists in the south both for prior Caucasian slave owners and for freed African American slaves. The thing is as a result of segregation the freed African American slaves grouped together to form their churches while the Caucasian prior slave owners kept their churches "pure" meaning kept African Americans out of their churches. The fact is that because there still are African American churches in the south is proof of the segregation which had existed way back then.
