Busk is a name for the Native American harvest ceremony also known as the Green Corn Ceremony.
The word Busk comes from a Creek term meaning fast. The ceremony traditionally involved fasting, purification, the extinguishing and relighting of household fires, and the eating of newly ripened corn. It marked the beginning of a new annual cycle and provided a time for renewal, forgiveness, social gathering, and thanksgiving.
The observance was especially important among Southeastern peoples, including the Muscogee, Seminole, Yuchi, and Cherokee, though practices and names differed between nations. Not every community used the word Busk, and modern ceremonies vary considerably.
The Green Corn Ceremony is not a single uniform festival with one universal date. Timing depends on when the corn ripens and on the traditions of each nation. It also should not be treated as interchangeable with a powwow, which is a different type of gathering.
