Archaeologists have analyzed the chemical makeup of glass beads from across the Great Lakes region of North America, revealing the extent of Indigenous influence on transatlantic exchange networks during the 17th century AD.

Glass beads were a key component of trade between Europeans and Indigenous Americans during early interactions between the two continents. One of the key actors in these networks was the Wendat Confederacy, which was based in southern Ontario until around 1650, when some Wendat people moved into the Western Great Lakes region.

Beads are a key symbol of European colonization, as they were produced in Europe but had a lasting impact on Indigenous Americans, with beadwork continuing to be integral to many Indigenous cultures to this day.

As such, it was thought that trans-Atlantic bead exchange networks must have been driven by European colonization. The first Europeans colonized the Western Great Lakes region around 1670.
