Connecticut finally ceded sovereignty over the Western Reserve in 1800. The United States absorbed it into the Northwest Territory, which organized Trumbull County within the boundaries of the Reserve. Warren, Ohio is the former county seat of the Reserve and identifies itself as "the historical capital of the Western Reserve." Later, several more counties were carved out of the territory. The name "Western Reserve" survives in the area in various institutions such as the "Western Reserve Historical Society" and Case Western Reserve University in Cleveland.
