Conrad Russell has recently asked, not for the first time, how far the divided allegiances of members of the Long Parliament were anticipated in the parliaments of the 1620s. Many who sat as M.P.s in the third decade of the seventeenth century had died by the early 1640s, while not all those who still survived were either sufficiently vocal before 1629 or politically active after 1641 to be classifiable for the purposes of this exercise. Nevertheless, Professor Russell manages to assemble a small bloc of members whose earlier politico-religious sympathies and civil war alignments are both more or less known. This group of twenty-six men splits neatly 50:50 between Royalists and Parliamentarians. According to Russell, all that distinguished one from the other in the 1620s, and the sole effective predictor of their later allegiances, was religion. More specifically, the crucial variable turns out to be commitment to further godly reformation, strong in the case of future Parliamentarians, weak in the case of future Royalists. But for Russell's explicit rejection of any “supposed correlation between ‘Puritanism and Revolution,’” the casual reader might conclude that something resembling the Puritan Revolution was sneaking back into historio-graphical favor.
