Lewiston (ˈluːᵻstən; luistɔ̃) is the second most populous city in the U.S. state of Maine and the most central city in Androscoggin County. The city lies halfway between Augusta, the state's capital, and Portland, the state's most populous city. It is one-half of the Lewiston-Auburn Metropolitan Statistical Area, commonly referred to as "L/A." or "L-A." Lewiston exerts a significant impact upon the diversity, religious variety, commerce, education, and economic power of Maine. It is known for an overall low cost of living, substantial access to medical care, and a low violent-crime rate. In recent years, the city of Lewiston has also seen a spike in economic and social growth. While the dominant language spoken in the city is English, it is home to a significant Somali population as well as the largest French-speaking population in the United States (by population) while it is second to St. Martin Parish, Louisiana, in percentage of speakers.
The Lewiston area traces its roots to 1669 with the early presence of the Androscoggin tribe (the namesake of the county in which the city resides). In the late 18th century, in 1795, Lewiston was incorporated as Lewistown. The presence of the Androscoggin River and Lewistown Falls made the town an attractive area for manufacturing and hydro-power businesses. The rise of Boston rail and textile tycoon Benjamin Bates saw rapid economic growth rivaling that of Cambridge, Worcester, and Concord. Irish immigrants were recruited to build the railroad links and dig the canals for the textile mills. The Irish stayed, and worked the mills and established flourishing businesses, as evidenced by the McGillicuddy, Callahan, and other Blocks and the St.Joseph's and St.Patrick's churches. In the 1850 Census Lewiston was fully 23% Irish born. The increase in economic stimulus prompted thousands of Quebecers to migrate, causing a population boom; the populace rose from 1,801 in 1840 to 21,701 in 1890.
