Old Sarum was from 1295 to 1832 a parliamentary constituency of England (until 1707), of Great Britain (until 1800), and finally of the United Kingdom of Great Britain and Ireland. It was a so-called rotten borough, with an extremely small electorate that was consequently vastly over-represented and could be used by a patron to gain undue influence. The constituency was on the site of what had been the original settlement of Salisbury, known as Old Sarum. The population and cathedral city had moved in the 14th century to New Sarum, at the foot of the Old Sarum hill. The constituency was abolished under the Reform Act 1832.
