Iroquois wampum belts are significant historical documents because they served as essential mnemonic devices used to record and preserve important agreements, treaties, and ceremonial events.12

Rather than functioning merely as currency, these belts were crafted from tubular shell beads woven into specific patterns that acted as a formal record of diplomatic relations and tribal history. By encoding information into these visual designs, the Iroquois and other Indigenous peoples could accurately recall the terms of treaties and the significance of various agreements, ensuring their historical accuracy was maintained through generations. Their value was rooted in this ceremonial and archival function, representing a sophisticated method of documentation that predated and existed alongside European record-keeping practices.12
