Anthony Ascham in the first part of the Discourse said that, according to jus belli, 'possession' was the prerequisite for rightful obedience. In the second part, he went to speak 'to subjects obeying an usurper power, after an obligation of Allegiance to another Power'. In The Bounds and Bonds Ascham replied to the Presbyterian opponents of the republican government saying that 'things are considerable only so far as they may reach the ends for which they are'. His response drew mainly on Hugo Grotius's De Jure, and expressly on his treatment of the sovereign rights deriving from victorious war grounded in the law of nations. Ascham's political argument in support of the politics implemented by his patrons in the Parliament, and, after Pride's Purge, in the Rump, was mainly drawn from Grotius. The Machiavelli on which Ascham drew (like in most of his sources) was arguably that of The Prince.
