West Warwick was incorporated in 1913, making it the youngest town in the state. Prior to 1913, the town, situated on the western bank of the Pawtuxet River, was the population and industrial center of the larger town of Warwick. The town split because local Democratic politicians wanted to consolidate their power and isolate their section of town from the Republican-dominated farmland in the east. Since then, the town of West Warwick has fallen on hard times after the collapse of the state's textile industry, while Warwick has gone on to be the state's second largest city and commercial center.
