Ferdinando Fairfax, 2nd Lord Fairfax of Cameron was an English nobleman and politician who sat in the House of Commons at various times between 1614 and 1648. He was a commander in the Parliamentary army in the English Civil War.

Thomas Fairfax, 3rd Lord Fairfax of Cameron, also known as Sir Thomas Fairfax, was an English politician, general and Parliamentary commander-in-chief during the English Civil War. An adept and talented commander, Fairfax led Parliament to many victories, including the crucial Battle of Naseby, effectively becoming military ruler of England, but he was eventually overshadowed by his subordinate Oliver Cromwell, who was more politically adept and radical in action against Charles I. Fairfax became dissatisfied with Cromwell's policy and publicly refused to take part in Charles's show trial. Eventually he resigned, leaving Cromwell to control the country. Because of this, as well as his honourable battlefield conduct and active role in the Restoration of the monarchy after Cromwell's death, he was exempted from the retribution that was exacted on many other leaders of the revolution.
