Warren was initially inhabited by Native Americans of the Seneca nation. French explorers had claims to the area but control was transferred to the British after the French and Indian War. After the Revolutionary War, General William Irvine and Andrew Ellicott were sent to the area to lay out a town in 1795. The first permanent structure in Warren, a storehouse built by the Holland Land Company, was completed in 1796. Daniel McQuay of Ireland was the first permanent inhabitant of European descent.
   Lumber was the main industry from 1810–1840, as the abundance of wood and access to water made it profitable to float lumber down the Allegheny River to Pittsburgh.
   David Beaty discovered oil in Warren in 1875 while drilling for natural gas in his wife's flower garden. Oil came to dominate the city's economy.
