The significance of the
Modus lies in its descriptions of the procedures and organisation of Parliament and the growing importance of the
Commons. Parliament had developed by the early 14th century to the point where it could promote the transmission of the crown's policies and intentions in a positive manner outwards from the centre, and representation was the best method of doing this; notably, the Commons were more representative than
magnates or
prelates, who only represented themselves. Increasingly, the agreement of the Commons was necessary for the levy of all taxes: peers could give such consent personally, whereas the Commons were proxies for the bulk of the population. During the reign of
Richard II, prominent members of the
House of Lancaster wished to play up the importance of the Commons, compared to that of the Lords, prelates and magnates, and to legitimate processes in the Commons to depose a king who had lost the support of the people. The
Modus was helpful to them in its emphasis on the representative power of the Commons: "We must understand that two Knights which come to the Parliament for the Shires and County out of which they come have a greater voice in Parliament to grant, than the greatest Earl in England". Maddicott offers a concise summary of the document's significance: "About the precise functions and powers of the commons the author of the
Modus was, so far as we can see, often wrong. But about their general weight and position he was not so far out ... It is not hard to envisage the sort of body which it had in mind playing its part in the deposition of a king". In a major political crisis in
Ireland in 1418–19, the veteran statesman
Christopher Preston, 2nd Baron Gormanston, was accused of
treason, largely on account of his ownership of a copy of the document. He was quickly released and restored to favour, apparently after explaining that he had simply found it among his father's papers and thought it worth keeping. This copy was itself copied onto the
patent roll of the
Irish Chancery. ==See also==
