"Algernon Sidney or Sydney (14 or 15 January 1623 \u2013 7 December 1683) was an English politician and member of the Long Parliament. A republican political theorist, colonel, and commissioner of the trial of King Charles I of England, he opposed the king's execution. Sidney was later charged with plotting against Charles II, in part based on his work, Discourses Concerning Government, used by the prosecution as a witness at his trial.
