Hiawatha is an important figure in the precolonial history of the Haudenosaunee (Iroquois) of present-day southern Ontario and upper New York (ca. 1400-1450). He is known most famously for uniting the Five Nations—Seneca, Cayuga, Onondaga, Oneida and Mohawk—into a political confederacy. In 1722, the Tuscarora, a tribe from much farther south, joined the Confederacy, forming what we now know as the Six Nations. The story of Hiawatha should not be confused with the popular poem by Henry Wordsworth Longfellow, The Song of Hiawatha (1885). While Longfellow references Hiawatha, the poem’s focus is actually an Algonquian cultural hero, Nanabozho. Whether this was an intentional or accidental error, Longfellow’s poem confused the history of Hiawatha.
