In February 1649, less than two weeks after Parliament 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".
