Created on March 12, 1800, from parts
of Allegheny and Lycoming Counties and named for General Joseph Warren. It was
attached to Crawford County until 1805 and then to Venango County until 1819
when it was formally organized. Warren, the county seat was laid out in 1795 and

French explorers visited the area in 1739 and 1749. Pennsylvania acquired the land from Indian nations in 1784, in the "Last Purchase." "Mad Anthony" Wayne's campaign in the Old Northwest, in 1794, finally made it safe for settlers to stay in northwestern Pennsylvania. David Mead contested the ownership with the Holland Land Company until 1796. The acrimony raised by "actual settlers" suits against the powerful absentee land companies' titles slowed the growth of the area. The Cornplanter reservation land was acknowledged to belong to the Seneca Indians from 1791 until the Kinzua Dam was completed, in 1964. At first, lumber was abundant and was floated down many streams to where it could be sold. The rafting lumber business lasted from 1800 to 1900. Today, second and third growth trees are harvested and logging companies continue, managed under regulations. Agriculture and population developed slowly, but oil and gas have been profitable since the 1870s. The county was especially favored by railroad access. Warren welcomed the Erie Railroad in 1859, followed by branches of the Pennsylvania and the New York Central. Metal, concrete, and tobacco products prospered here in the past. Oil refining and lubricant manufacturing are still important activities, as is furniture making. In the five years from 1987 to 1992, the county's figure for value added (to the national economy) from manufacturing rose 86 percent Although 15 percent of land is in farms, meat and dairying are the areas in which agricultural receipts are competitive with other rural counties.
As reported by the Census Bureau, the county has a total area of 898 square miles (2,325 km2), of which, 883
square miles (2,288 km2) of it is land and 14 square miles (37 km2) of it (1.60%) is water.
