Cornwall is a former county constituency covering the county of Cornwall, in the South West of England. It was a constituency of the House of Commons of England then of the House of Commons of Great Britain from 1707 to 1800 and of the House of Commons of the United Kingdom from 1801 to 1832. It was represented by two Knights of the Shire, elected by the bloc vote system.

Under the Reform Act 1832, it was divided between the constituencies of East Cornwall and West Cornwall.

Boundaries and franchise The constituency consisted of the whole of the historic county of Cornwall, the most south-westerly county of England, occupying the part of the South West peninsula to the west of the River Tamar which divides the county from Devon. (Although Cornwall contained a number of parliamentary boroughs, each of which elected two MPs in their own right, these were not excluded from the county constituency, and owning property within a borough could confer a vote at the county election. For a summary of the boroughs represented before 1832 see Parliamentary representation from Cornwall.)

As in other county constituencies the franchise between 1430 and 1832 was defined by the Forty Shilling Freeholder Act, which gave the right to vote to every man who possessed freehold property within the county valued at £2 or more per year for the purposes of land tax; it was not necessary for the freeholder to occupy his land, nor even in later years to be resident in the county at all.

By the time of the Great Reform Act in 1832, the population of Cornwall was about 300,000. Only a tiny fraction of these were entitled to vote. Sedgwick estimated there were about 2,300 electors in this constituency in the 1715–1754 period, and Namier and Brooke suggest this had increased to about 2,500 electors in the 1754–1790 period. At the vigorously contested election of 1790, when a high turnout can be assumed, 4,656 valid votes were cast (each voter being entitled to vote twice). At Cornwall's final election, in 1831, 5,350 votes were cast.

1510–1629 As there were sometimes significant gaps between Parliaments held in this period, the dates of first assembly and dissolution are given. Where the name of the member has not yet been ascertained or (before 1558) is not recorded in a surviving document, the entry unknown is entered in the table.

The Roman numerals after some names are those used in The House of Commons 1509–1558 to distinguish a member from another politician of the same name.

In 1529 alternative versions are given of the names for one member. The first comes from the above book on the House of Commons. The second originates from another source.

Elections

The bloc vote electoral system was used in two seat elections and first past the post for single member by-elections. Each elector had as many votes as there were seats to be filled. Votes had to be cast by a spoken declaration, in public, at the hustings, which were usually held at the county town. The expense and difficulty of voting at only one location in the county, together with the lack of a secret ballot contributed to the corruption and intimidation of electors, which was widespread in the unreformed British political system.

The expense, to candidates and their supporters, of contested elections encouraged the leading families of the county to agree on the candidates to be returned unopposed whenever possible. Contested county elections were therefore unusual.

There were no contested general election polls in Cornwall between 1710 and 1774. Leading Whig politicians, like Sir Robert Walpole, were happy to let Tory squires represent the county; to avoid them interfering with Whig plans in the county's numerous borough constituencies. The related families of Carew, Molesworth, St Aubyn and Buller monopolised the representation for much of the 18th century, until the partners in the Miners' Bank at Truro, Humphrey Mackworth Praed and William Lemon, became involved in elections in the 1770s.
