A wampum refers to traditional shell beads used by Native American tribes, particularly in the northeastern United States. Made from shells such as quahog and whelk, wampum was historically used for various purposes, including as currency, in ceremonial gifts, and to record treaties and important events. The beads are often woven into belts or necklaces, symbolizing social status and cultural significance. Today, wampum continues to hold cultural importance and is valued for its artistry and historical meaning.
