Richard Cromwell resigned as Lord Protector on 25 May 1659. The Protectorate, which had seemed the strongest alternative to monarchy after the execution of Charles I, was over.

Richard had inherited the office after Oliver Cromwell died in 1658. He had the title, but little of the authority that had made his father powerful. Oliver had been a soldier, a political force and the figure around whom the army and government had gathered. Richard was not that kind of ruler.

The weakness soon showed. The army remained a decisive political power, and it did not accept Richard as his father’s equal. Parliament gave him no firm base either. The Protectorate had been built to hold together a country that had abolished monarchy, fought over religion and government, and struggled to replace a king with something stable.

When Richard resigned, power passed back to the restored Rump Parliament. This did not settle the problem. It returned England to an earlier debate over who had authority after the monarchy was removed: Parliament, the army, or some new form of executive power.

The resignation did not make the Restoration inevitable. It made the failure of the post-1649 settlement harder to ignore. The Protectorate had seemed to offer order after years of civil war and political experiment. Richard Cromwell’s fall showed how much that order had depended on Oliver Cromwell himself.
