Convention Parliament (1660)
The Convention Parliament of England (25 April 1660 – 29 December 1660) followed the Long Parliament that had finally voted for its own dissolution on 16 March that year. Elected as a "free parliament",  i.e. with no oath of allegiance to the Commonwealth or to the monarchy, it was predominantly Royalist in its membership. It assembled for the first time on 25 April 1660.

After the Declaration of Breda had been received, Parliament proclaimed on 8 May that King Charles II had been the lawful monarch since the death of Charles I in January 1649. The Convention Parliament then proceeded to conduct the necessary preparation for the Restoration Settlement. These preparations included the necessary provisions to deal with land and funding such that the new régime could operate.

Reprisals against the establishment which had developed under Oliver Cromwell were constrained under the terms of the Indemnity and Oblivion Act which became law on 29 August 1660. Nonetheless there were prosecutions against those accused of regicide, the direct participation in the trial and execution of Charles I.

The Convention Parliament was dissolved by Charles II on 29 December 1660. The succeeding parliament was elected in May 1661, and was called the Cavalier Parliament. It set about both systematically dismantling or recasting all legislation and institutions which had been introduced during the Interregnum, and the confirming of the Acts of the Convention Parliament.
