or Ruglen, a parliamentary, municipal, and royal burgh of Scotland, county of Lanark, on the left bank of the Clyde, 2 miles S.E. of Glasgow. It has one main street of considerable breadth, extending from E. to W., and many smaller streets and lanes diverging from it. There are no public buildings of any importance except the town-hall, parish church, chapel of ease, Free and United Presbyterian churches. The parish church is ancient, and it is said to have been here that the treaty was made in 1297 between Edward I. of England and Sir John Menteath, by which the latter agreed to betray Wallace to the English. The castle that formerly stood at Rutherglen was demolished by the Regent Murray. The town contains a court-house, prison, and several schools. The inhabitants are very generally employed in hand-loom weaving. There are chemical works, print and dye works here; and in the vicinity several coal mines. Formerly the town was of considerable importance, and had a large trade on the Clyde; but this has been absorbed by Glasgow, with the suburbs of which Rutherglen is connected by an old narrow bridge. Several annual fairs are held. The burgh was first chartered by David I. in 1126, and is governed by a provost, two bailies, and eighteen councillors. It unites with Kilmarnock, Dumbarton, Port-Glasgow, and Renfrew in returning a member to Parliament; and the constituency is 194. The value of real property, 1858-9, was L23,304; and the corporation revenue, 1857-8, L1633. Pop. (1851), 7104.
