For how long was Britain a republic under the leadership of Oliver Cromwell?
Correct Answer: 11 years
Britain was a republic under Oliver Cromwell for 11 years (1649–1660).
After King Charles I was executed in 1649, England became a Commonwealth (republic) governed by Parliament and then a Protectorate under Cromwell as Lord Protector.
The monarchy was restored in 1660 when Charles II returned from exile — an event known as the Restoration.
