BEACONSFIELD, urban district, South Buckinghamshire, England. Pop. It lies just off the chalk of the Chilterns, in a hilly district above the valley of the small River Wye, a tributary of the Thames, giving access to High Wycombe and thus to North Bucks and Oxfordshire. It grew as a posting station of some importance, and has revived its function as a route town with modern road traffic. The Oxford road forms its main street. The improvement of railway communication with London in 1 go6 led to an influx of resident population. (The population in 1901 was 1,S7o.) The Perpendicular church of St. Mary and All Saints is the burial place of Edmund Burke (d. I i97) who lived at Butler's Court, near the town. Benjamin Disraeli chose the title of Earl of Beaconsfield in 1876. There was formerly a considerable manufacture of ribbons. Since 1918 the town has formed part of the Aylesbury parliamentary county division.
