Richard Cromwell (4 October 1626 – 12 July 1712) was an English statesman who served as Lord Protector of the Commonwealth of England, Scotland and Ireland from 1658 to 1659. He was the son of Lord Protector Oliver Cromwell.
Following his father's death in 1658, Richard became Lord Protector, but he lacked authority. He tried to mediate between the army and civil society, and allowed a Parliament that contained many disaffected Presbyterians and Royalists to sit. Suspicions that civilian councillors were intent on supplanting the army peaked in an attempt to prosecute a major-general for actions against a Royalist. The army made a threatening demonstration of force against Richard, and may have had him in detention. He formally renounced power only nine months after succeeding.
Though a Royalist revolt was crushed by the recalled civil war figure General John Lambert, who subsequently prevented the Rump Parliament from reconvening and created a Committee of Safety, Lambert found his troops melted away in the face of General George Monck's advance from Scotland. Monck then presided over the Restoration of 1660.
