Why it matters
The catalogue describes this as a land cession document signed under Harrison's governorship of Indiana Territory. Such treaties recorded the transfer of land from Native nations to the United States, and they shaped the growth of the territory. The Kaskaskia are named in the title as one of the nations that signed. Signatures and seals show who agreed to the terms and how the agreement was made official.
