Wampum are beads made from seashells used by Native American groups to send messages, record important events like treaties, and for trade. Famous wampum belts included the Four Nations Belt symbolizing an alliance between Huron and French, the Two Row Wampum Belt representing a treaty between Dutch and Iroquois to live in peace, and the Hiawatha Belt symbolizing the founding of the Iroquois League. Different colors in wampum belts represented various meanings and symbols. Many wampum belts can now be found in museums.
