Denbighshire (UK Parliament constituency)

Denbighshire was a county constituency in Denbighshire, in north Wales, from 1542 to 1885.

History
From 1542, it returned one Member of Parliament (MP), traditionally known as the knight of the shire, to the House of Commons of the Parliament of England until 1707, then to the Parliament of Great Britain until 1800, and to the Parliament of the United Kingdom from 1801. These MPs were elected by the first past the post voting system.

Under the Reform Act 1832, the constituency's representation was increased to two members, elected by the bloc vote system.

The constituency was abolished by the Redistribution of Seats Act 1885 for the 1885 general election, when Denbighshire was split into two single-member constituencies: the Eastern and Western divisions, each returning one Member of Parliament.
