Monck marched into England in January 1660, as Lambert's supporters in the Army were cashiered and his authority crumbled. When Sir Thomas Fairfax emerged from retirement to declare his support for Monck, Army support for Monck became almost unanimous. Monck entered London in February 1660 and he allowed the Presbyterian members, 'secluded' in Pride's Purge of 1648, to re-enter parliament on 21 February 1660 on the condition that the restored Long Parliament would agree to dissolve themselves once general elections had been held. The "Long Parliament" dissolved itself on 16 March 1660, after preparing legislation for the Convention Parliament that formally invited King Charles II to be the English monarch in what has become known as the Restoration (of the House of Stuart).
