Circumcision has been, and is still, practiced among many primitive tribes for religious reasons.

The earliest practitioners of circumcision were the black African tribes, where the practice was (and still is) very widespread, the Australian Aborigines, and the Egyptians. These black African tribes, and the Egyptians, are known to have practiced circumcision more than 6,000 years ago.

Many other cultures, e.g., the Aztecs, the Mayans, most American Indian tribes, the Caribs, the Malays and Polynesians, also practiced circumcision.

Most of these cultures circumcise, when the boy becomes a man, as required by their religion.
