How did stuarts gain power back from cromwell?

The Stuarts regained power from Oliver Cromwell through the Restoration of the monarchy in 1660, following Cromwell's death in 1658 and the subsequent political instability of the Protectorate. Charles II was invited back from exile in France, as many were disillusioned with the strict Puritan rule and sought a return to traditional monarchy. The lack of a strong successor to Cromwell and the failure of the republican government to establish legitimacy facilitated the monarchy's return. The Restoration was marked by the re-establishment of the Church of England and the revival of royal authority.
