In the House of Commons of England, each English county elected two "knights of the shire" while each enfranchised borough elected "burgesses" (usually two, sometimes four, and in a few cases one). From 1535 each Welsh county and borough was represented, by one knight or burgess. The franchise was restricted differently in different types of constituency; in county constituencies forty shilling freeholders (i.e. landowners) could vote, while in boroughs the franchise varied from potwallopers, giving many residents votes, to rotten boroughs with hardly any voters. A "county borough" was the constituency of a county corporate, combining the franchises of both county and borough. Until 1950 there were also university constituencies, which gave graduates an additional representation.
