Lucas County is a county located in the northwestern part of the U.S. state of Ohio. It is bordered to the east by Lake Erie, and to the southeast by the Maumee River, which runs to the lake. As of the 2020 census, making it the sixth-most populous county in the state, the population was 431,279. Its county seat and most populous city is Toledo, located at the mouth of the Maumee River on the lake. The county was named for Robert Lucas, 12th governor of Ohio, in 1835 during his second term. Its establishment provoked the Toledo War conflict with the Michigan Territory, which claimed some of its area. Lucas County is the central county of the Toledo Metropolitan Statistical Area.

History

On August 20, 1794, near the site of the present-day town of Maumee, American forces led by General Anthony Wayne won a decisive victory over allied Indian forces at the Battle of Fallen Timbers after years of conflict in what was known as the Northwest Indian War. The defeat of the Native forces resulted in the opening of the entire Northwest Territory for white settlement. Northwest Ohio was occupied chiefly by villages and bands of the Odawa people, who had trading relations with the French at Fort Detroit since 1701. Other Odawa were located in southeast Michigan and further north on the peninsula. They ceded much of that territory in the Treaty of Greenville but retained control of lands along the Maumee River until after the War of 1812. The last Odawa band, that of Ottokee, grandson of Chief Pontiac, left the Maumee River area for Kansas in 1839.

Lucas County was established in 1835. At that time, both Ohio and Michigan Territory claimed sovereignty over a region along their border (see Toledo War). When Michigan petitioned Congress for statehood in 1835, it sought to include the disputed territory within its bounds. In response, the Ohio General Assembly formally organized part of the area as Lucas County, naming it after the incumbent governor of Ohio, Robert Lucas.
