He acted as a diplomat to protect Chickasaw people and sovereignty. Piominko met with other Southeastern tribes, governors of states and President George Washington to reach agreements that benefitted his people. One of his greatest achievements was the signing of the Treaty of Hopewell in 1786, which formalized the tribe’s alliance with the U.S. government.
