BELLEVILLE, a city and the county-seat of St Clair county, Illinois, U.S.A., in the S.W.
Belleville is served by the Illinois Central, the Louisville & Nashville, and the Southern railways, also by extensive interurban electric systems; and a belt line to O'Fallon, Illinois, connects Belleville with the Baltimore & Ohio South Western railway.
Belleville is in a rich agricultural region, and in the vicinity there are valuable coal mines, the first of which was sunk in 1852; from this dates the industrial development of the city.
Belleville was first settled in 1813, was incorporated as a city in 1850, and was re-incorporated in 1876.
On this account Hecker resolved in September 1848 to emigrate to North America, and obtained possession of a farm near Belleville in the state of Illinois.
