The Oxford Parliament (also known as the King's Oxford Parliament or Mongrel Parliament) was the Parliament assembled by King Charles I for the first time 22 January 1644 and adjourned for the last time on 10 March 1645, with the purpose of instrumenting the Royalist war campaign. The first session lasted from 22 January 1644 until 16 April 1644. The second session was from 8 October 1644 until 10 March 1645. Not much is known of its proceedings because all its records were burnt just before Oxford fell to Parliamentary forces in 1646.
