In the seventeenth‑century Northeast, diplomacy and trade between the Dutch of New Netherland and Indigenous nations—especially the Haudenosaunee (Iroquois), Munsee‑Lenape, and Mahican—ran on shell currency and memory encoded in beads. The Dutch called it seawan (wampum). Indigenous diplomats used strings and belts to convene councils, fix relationships, and refresh old promises. Together they built a bilingual protocol: Dutch merchants and magistrates regulated wampum as money for daily exchange; Indigenous leaders deployed wampum as law, history and consent. This page follows how that shared system shaped treaties, borders and the language of alliance.
From the 1620s the fur trade pulled beaver pelts down the Mohawk–Hudson corridor to Fort Orange (today’s Albany) and New Amsterdam. To grease everyday transactions, the Dutch adopted seawan—small shell beads—because coin was scarce on the frontier. In 1650 Director‑General Peter Stuyvesant and his council formally regulated seawan as small‑change currency, even specifying what counted as acceptable strings and requiring shopkeepers and bakers to accept it for “small and daily necessities.” In a world where a mug of beer, a loaf of bread, or a ferry fare might be paid bead‑by‑bead, seawan filled the gap between barter and bullion.
These ordinances weren’t just about prices; they were about quality. Officials complained about “half‑finished” or counterfeit beads of glass, stone, or bone. They set rules for strung versus loose seawan and capped how much could be tendered in small deals. In short, Dutch law adapted to an Indigenous monetary technology because it worked—and because Indigenous producers and traders controlled much of the supply.
For Haudenosaunee and Algonquian‑speaking neighbors, wampum had long been a medium of record. A string summoned a council; a belt embodied the words spoken there. Belts memorialized the terms of peace, kinship, condolence, or alliance and could be “read” aloud by trained speakers. When Dutch merchants arrived, Indigenous diplomats used the same protocol to shape the relationship, and Dutch agents—pragmatic traders at heart—learned to listen for the meaning carried in beads.
Haudenosaunee oral history places the first covenant with the Dutch in the early 1600s and expresses it in the Two Row Wampum: a white field (the river) crossed by two purple rows (a canoe and a ship) traveling side‑by‑side in perpetuity. Over time another metaphor joined it—the Iron, later Silver, Covenant Chain—symbolizing a friendship that must be regularly “polished” to keep it bright. Some modern scholars dispute a surviving written “1613 treaty” document (often called the Tawagonshi paper), but the diplomatic tradition of parallel paths and chain‑renewal was real, repeatedly performed in council and reinforced with belts. The imagery later carried into the English era as the “Covenant Chain” centered on Albany.
New Netherland’s up‑river hub at Fort Orange (with the Dutch town of Beverwijck alongside) became a clearinghouse for peace talks and trade. After the bloodletting of Kieft’s War on the lower Hudson (1643–45), Dutch officials concluded articles of peace with local nations at Fort Orange in August 1645. In the middle Mohawk Valley, traders such as Arent van Curler earned reputations as interpreters and go‑betweens; the Mohawk even used “Corlaer” as a title for subsequent governors of New York. Wampum strings and belts structured these meetings: who speaks, who answers, and how old grievances are acknowledged and bound up.

Downriver, the Dutch sought written deeds for tracts on Manhattan, Staten Island and Long Island—transactions later remembered as “purchases.” A famous 1626 letter reported that Manhattan had been “acquired” for goods worth sixty guilders. But Indigenous land tenure emphasized layered use and kin ties, not absolute alienation in the European sense. Many so‑called sales were more like agreements to share space and maintain peaceful exchange; conflicting expectations surfaced quickly when cattle strayed, fences went up, or a magistrate read a deed in court decades later. Wampum featured here too—strings circulated at meetings to call people together and mark consent, even as Dutch notaries drafted parchment copies for their archives.
In 1650, Dutch and English commissioners negotiated the Treaty of Hartford to reduce friction between New Netherland and the expanding English colonies. The boundary ran through Long Island and up the mainland—an imperial line negotiated without Indigenous consent that nonetheless cut across Indigenous homelands. Even here, wampum resonated in the background: it financed frontier markets where English, Dutch, and Native traders mingled, and its flow into, and out of, New Amsterdam helped set prices for everything from beaver to bread.

When English warships appeared off New Amsterdam in August 1664, the colony surrendered under Articles of Capitulation that protected Dutch property, customs and worship. Indigenous diplomacy did not stop; it re‑channeled. The “Corlaer” relationship with the Mohawk flowed into the broader English‑Haudenosaunee Covenant Chain built out of Albany. Wampum continued to structure councils and record obligations—proof that the underlying cross‑cultural protocol outlasted the flag change.
Three legacies endure. First, material: strings and belts still held in Native communities and museums remain living records, brought out for ceremony and law. Second, legal‑political: the imagery and language of the Two Row and the Chain still frame how Haudenosaunee nations describe relations with neighboring governments. Third, economic: the Dutch encounter shows how a European colony could bend toward Indigenous money and protocol when it needed to—an early North American example of a negotiated, not merely imposed, order.
