city, Rock Island county, northwestern Illinois, U.S. It lies on the Mississippi River (there bridged to Iowa). With East Moline and Rock Island, Illinois, and Davenport and Bettendorf, Iowa, it forms a complex known as the Quad Cities. Sauk and Fox Indians inhabited the area at the time of the first settlement; conflicts over territory led to the Black Hawk War (1832). The site was laid out in 1843 by a group of settlers engaged in milling operations. Its name is apparently from the French moulin ("mill"). After the American Civil War, Swedish and Belgian immigrants arrived. John Deere, inventor of an improved steel plow, established a workshop there in 1848, and Moline was soon a centre of plow production. The city, once called "Plow City," remains the world headquarters for John Deere, and farm implements continue to be the primary economic factor in Moline. Aluminum and elevators are also produced, and food processing and the military (at the nearby Rock Island Arsenal) are important to the local economy as well. Moline is the seat of Black Hawk (community) College (1946); there is also a campus of Western Illinois University. The John Deere Pavilion (1997) includes exhibits on agriculture and displays of modern and vintage farm equipment. The company's administrative centre (1963) was designed by Eero Saarinen. A 12,000-seat arena (1993) hosts concerts and sporting events. Inc. town, 1848; reinc. 1855; city, 1872. Pop.
