Warren

Warren is a city in northeastern Ohio, United States, and the county seat of Trumbull County. Ephraim Quinby founded it in 1798 on 441 acres of land that he bought from the Connecticut Land Company, as part of the Connecticut Western Reserve, and named it for the surveyor Moses Warren. It was the historical county seat of the Western Reserve and became the Trumbull County seat in 1801. The city lies along the Mahoning River, about 14 miles northwest of Youngstown and 56 miles southeast of Cleveland, and it is a principal city of the Mahoning Valley metropolitan area. Steel production was a major industry in the county in the late nineteenth and early twentieth centuries because of coal and iron ore in the surrounding counties. The 2020 census counted 39,201 residents.
