During which period did Oliver Cromwell rule England as Lord Protector?

• A. Restoration
• B. Glorious Revolution
• C. Elizabethan Era
• D. Interregnum

Answer: (D)

The main idea here is the period between monarchs when England experimented with republican and constitutional rule—the Interregnum. After Charles I was executed and the monarchy was abolished, England did not have a king. During this time, Oliver Cromwell became Lord Protector and led the state from 1653 to 1658, a stint known as the Protectorate. This era sits inside the Interregnum, the long gap between kings, which is why it’s the best label for when Cromwell ruled in that capacity. The Restoration in 1660 brought back the monarchy under Charles II, Elizabethan times happened well earlier, and the Glorious Revolution occurred later, so those periods don’t describe the time of Cromwell’s leadership as Lord Protector.
