Why were the "Five Civilized Tribes" considered to be civilized?

The word civilized was applied to the five tribes because, broadly speaking, they had developed extensive economic ties with whites or had assimilated into American settler culture. Some members of these southeastern tribes had adopted European clothing, spoke English, practiced Christianity, and even owned slaves.
