Monroe was first settled in 1800 and was officially incorporated in 1822. The town was named for President James Monroe, who was in office at the time of incorporation. The town was mostly rural, with dairy farming taking up much of the town's economic activity. During the mid-19th century, the town did get some business from the building of the Hoosac Tunnel, just south of town in Florida. In 1885, however, a railroad line was built between neighboring Readsboro, Vermont, and Holyoke to haul wood pulp to a paper factory. This, in turn, enticed the Ramage family to establish the James Ramage Paper Company in 1887. The company was the main industry well into the 20th century, before closing in 1984
Monroe is part of the Springfield, Massachusetts Metropolitan Statistical Area. Source: Wikipedia
