The next recorded milestone in the development of human rights was the Petition of Right, produced in 1628 by the English Parliament and sent to Charles I as a statement of civil liberties. Refusal by Parliament to finance the king’s unpopular foreign policy had caused his government to exact forced loans and to quarter troops in subjects’ houses as an economy measure. Arbitrary arrest and imprisonment for opposing these policies had produced in Parliament a violent hostility to Charles and to George Villiers, the Duke of Buckingham.
