In negotiating the Treaty of Fort Wayne in 1809, William Henry Harrison angered Shawnee chief Tecumseh by acquiring land from several Native American tribes without the consent of all the tribes involved, particularly the Shawnee. Tecumseh viewed this as a blatant disregard for Native sovereignty and rights, as it undermined the unity of Native nations against encroaching American settlers. This act contributed to rising tensions between the United States and Native American tribes, ultimately leading to further conflict.
