Note: By the time the first European explorers arrived in North America in the late 1400s, the original indigenous people had inhabited what is today the State of Ohio for over 14,000 years. Starting with Ohio’s earliest ancient inhabitants, American Indian tribes and nations built and sustained rich, sophisticated, and productive societies and cultures. Ohio was not discovered by European explorers or settlers, as these lands were already claimed by American Indian groups as ancestral homelands, and many American Indians today consider Ohio their true home.

  • 1640: Beaver Wars–The Haudenosaunee, also called the Five Nations (later called the Six Nations in 1722), start a campaign called the Beaver Wars, during which they fight other American Indian groups, including those in Ohio Country, for their lands and territories in order to gain access to their fur–bearing animal game, especially beavers and deer.

While the Iroquois agree to give up this land, other tribes living in Ohio do not, including the Lenape, Seneca–Cayuga, and Shawnee Tribes.
  • 1774: Lord Dunmore's War–Anglo–American settlers ignore the Proclamation of 1763, which led to violent confrontations with American Indian groups in Ohio Country.

    • 1795:Treaty of Greeneville (1795)–After eight months of negotiations, American Indian tribal leaders and the United States sign the Treaty of Greeneville, which relinquishes all Indian Territory south and east of the treaty line, and white settlers cede all land north and west of the treaty line.
