Rump Parliament

The Rump Parliament describes the members of the Long Parliament who remained in session after Colonel Thomas Pride, on 6 December 1648, commanded his soldiers to purge the House of Commons of those members who were against the Grandees' intention to try King Charles I for high treason.

"Rump" normally means the hind end or backside of a mammal; its use meaning "remnant" (the reduced-membership Parliament) was first recorded in the above context in English in 1649.
