Oliver Cromwell (1599 – 1658) was an English military and political leader and later Lord Protector of the Commonwealth of England, Scotland and Ireland. Cromwell is one of the most controversial figures in the history of the British Isles, considered a regicidal dictator by historians such as David Hume, a military dictator by Winston Churchill, but a hero of liberty by Thomas Carlyle and Samuel Rawson Gardiner, and a class revolutionary by Leon Trotsky.

Thomas Carlyle (1795 – 1881) was a Scottish philosopher, satirical writer, essayist, historian and teacher during the Victorian era. He called economics "the dismal science", wrote articles for the Edinburgh Encyclopedia, and became a controversial social commentator. In later writings, Carlyle sought to examine instances of heroic leadership in history. The Letters and Speeches of Oliver Cromwell (1845) presented a positive image of Cromwell: someone who attempted to weld order from the conflicting forces of reform in his own day. Carlyle sought to make Cromwell's words live in their own terms by quoting him directly, and then commenting on the significance of these words in the troubled context of the time. Again this was intended to make the 'past' 'present' to his readers.
