SOME apology may seem necessary for a brief paper that covers nearly three centuries, but, unless we take long views, we are unlikely to get into focus the problem before us, namely, the extent to which the commons participated in medieval politics and the manner in which they did so. Bishop Stubbs, you will remember, found this a matter of particular difficulty. The part played by the commons in relation to taxation and legislation seemed plain enough. But political power, the ‘right of general deliberation on all national matters, is too vague in its extent’, he thought, ‘to be capable of being chronologically defined; nor was it really vindicated by the parliament until a much later period than’ the reign of Edward I, with which he was then concerned. Elsewhere, Stubbs seems to have committed himself to the view that the commons took part in politics in the fifteenth century, although the distinction he formerly drew between politics and legislation he no longer maintained. Quite clearly we cannot consistently maintain a distinction between politics and legislation or politics and finance. ‘The right of deliberation on all national matters’, in Stubbs's phrase, may express itself in the acceptance or refusal of legislative or of financial proposals. But if there are certain national matters from the discussion of which one or other of the ‘estates’ is in practice excluded, then it is reasonable to say that, to that extent, they take no part in politics. To suggest an obvious example: the assent of the lower clergy was necessary to the taxation to which they were subjected; they took no part in general legislation; and they certainly did not exercise the right of deliberation on all national matters. Their participation in politics was therefore of the slightest.
