Warren was established in 1798 on 441 acres (1.78 km2) of property acquired from the Connecticut Land Company as part of the Connecticut Western Reserve. Ephraim Quinby was the first mayor of Warren. Quinby named the town after Moses Warren, who served as the settlement's surveyor. The town served as the county seat of the Western Reserve until becoming the county seat of Trumbull County in 1801.
Warren had county facilities, two printing offices, a bank, five mercantile businesses, and a population of around 600 people when the census was taken in 1833.
In 1846, the town of Warren had a population of around 1,600 people. In the same year, the town had five churches, twenty businesses, three newspaper offices, one bank, one wool factory, and two flourmills, all of which were closed down. Residents quickly rebuilt the damaged buildings on one side of the town square when a fire broke out in June 1846, replacing them with new shops and other enterprises. For farmers who lived in the surrounding countryside during this time period, Warren became as a significant centre of commerce for them. Stephen Foster, his wife Jane McDowell, and their daughter Marion spent a short period of time in Warren before moving away.
