Iron Nation

Solomon Iron Nation (Lakota: Ma'-Zu-Oya'-Te; February 1815 – November 15, 1894), often just referred to as Iron Nation, was a principal chief—and the last Head Chief—of the Lower Brule Lakota. He signed multiple treaties with the United States government, including the Fort Laramie Treaties of 1851 and 1868. His leadership oversaw the creation of the Lower Brule Indian Reservation.
