The Petition of Right is a major English constitutional document that sets out specific liberties of the subject that the king is prohibited from infringing. Passed on 7 June 1628, the Petition contains restrictions on non-Parliamentary taxation, forced billeting of soldiers, imprisonment without cause, and restricts the use of martial law. Following disputes between Parliament and King Charles I over the execution of the Thirty Years` War, Parliament refused to grant subsidies to support the war effort, leading to Charles gathering "forced loans" without Parliamentary approval and arbitrarily imprisoning those who refused to pay. Moreover, the war footing of the nation led to the forced billeting of soldiers within the homes of private citizens, and the declaration of martial law over large swathes of the country.
