In February 1649, less than two weeks after the
Parliament of England executed Charles I, Milton published
The Tenure of Kings and Magistrates to justify the action and to defend the government against the
Presbyterians who initially voted for the
regicide and later condemned it, and whose practices he believed were a "growing threat to freedom." Milton aimed to expose false reasoning from the opposition, citing
scripture throughout
the Tenure of Kings and Magistrates to counter
biblical reference that would cast holy and public disapproval on Parliament's actions. "Milton’s case was not that Charles I was guilty as charged, but that Parliament had the right to prosecute him." Milton later remarked that the piece was "written to reconcile men's minds, rather than to determine anything about Charles". The work also rebuts theories posited by
Robert Filmer and
Thomas Hobbes. The work appeared five times: in 1649, perhaps written during the King's trial, with a second edition following in 1650 ("with improvements" during a controversy over the succession of
William III of England. This edition, titled
Pro Populo Adversus Tyrannos: Or the Sovereign Right and Power of the People over Tyrants, may have been edited by
James Tyrell, a historian, but continued to be advertised, in 1691, as being Milton's work. == Tract ==
