First explored for France by sieur de la Salle in 1669, the Ohio region became British property after the French and Indian Wars. Ohio was acquired by the U.S. after the Revolutionary War in 1783. In 1788, the first permanent settlement was established at Marietta, capital of the Northwest Territory.
The 1790s saw severe fighting with the Indians in Ohio; a major battle was won by Maj. Gen. Anthony Wayne at Fallen Timbers in 1794. In the War of 1812, Commodore Oliver H. Perry defeated the British in the Battle of Lake Erie on Sept. 10, 1813.
