Breconshire (UK Parliament constituency)
Breconshire or Brecknockshire was a constituency in Wales which returned one Member of Parliament to the House of Commons of the English Parliament, and later to the Parliament of Great Britain and of the United Kingdom, between 1542 and 1918. (Historically, the "-shire" suffix was often omitted, leading to potential confusion with the Brecon borough constituency, which existed until 1885.)
