Arthur St. Clair, one of the co-founders of Dayton, was a staunch Federalist and opposed Ohio becoming a state. As Governor of the Northwest Territory, he believed that Federalists could keep control by keeping the states small. The population requirement to become a state was 60,000. For reference, Kettering’s population in 2017 was 55,175.
On April 30, 1802, Thomas Jefferson signed the Enabling Act that laid that groundwork for Ohio to become a state.
