1640 - i66o 59 studying the revolution in the capital, sho\vs the stages by which the conservative and royalist pre-war regime was over- thrown by a revolutionary party.344 It remains to discover just how or why a confrontation occurred which even in November 1640 was out of the question; the one attempt at answering this question, made by Zagorin (n. 31i), seems to me to assume too much coherence in Pym's party and policy, and not to recog- nize sufficiently that the bulk of the people involved were in a very real sense surprised by war. We have two analyses of the Long Parliament. Brunton and Pennington have cnamierizedj the members elected in 1640; in the process they have found only one significant difference between those who later joined parliament or king, namely that the latter were on average younger.345 Keeler presents biographies of all who sat in that parliament during the first two years, describes elections, and offers no conclusions.346 The parliament's inner history, and especially the crucial problem of Pym's tactics, form the substance of six careful articles from one hand.347 Pearl takes a closer look at those parliamentarians who hoped to end the war.348 Trevor-Roper gains useful insights into political ideas and methods from 814 Valerie Pearl, London and the Outbreak of the Puritan Revolution.
