In 1832 the county of Cornwall, in south west England, was split for parliamentary purposes into two county divisions. These were the East division (with a place of election at Bodmin) and West Cornwall (where voting took place at Truro). Each division returned two members to Parliament.
The parliamentary boroughs included in the East division, from 1832 to 1885 (whose non-resident 40 shilling freeholders voted in the county constituency), were Bodmin, Launceston and Liskeard.
In 1885 this division was abolished, when the East and West Cornwall county divisions were replaced by six new single-member county constituencies. These were Bodmin (the South-Eastern division), Camborne (North-Western division), Launceston (North-Eastern division), St Austell (Mid division), St Ives (the Western division) and Truro. In addition the last remaining Cornish borough constituency was Penryn and Falmouth.
Writing about differences in dialects within Cornwall Thomas Q. Couch wrote in 1880: "If asked to define roughly a boundary, I know none better than the Parliamentary line from Crantock Bay, on St. George's Channel, to Veryan Bay, on the English Channel, which bisects the county."
