Biography

Algernon Sidney was a man of principle whose life was defined by opposition to tyranny, an stance that ultimately cost him his head. A soldier and diplomat from an aristocratic family, he served in the Long Parliament and fought for the Parliamentary cause in the English Civil War, though he notably opposed the execution of Charles I. After the Restoration, he lived in exile, writing his seminal 'Discourses Concerning Government', a forceful argument for popular sovereignty and against the divine right of kings. Returning to England, he was implicated in the Rye House Plot against Charles II. At his trial, the prosecution used his unpublished manuscript as evidence of treasonous intent, famously declaring 'scribbled, scribbled, scribbled' to mock his work. His execution transformed him from a failed conspirator into a potent symbol of republican liberty, his writings later inspiring American revolutionaries.
