This chapter describes and explains the early weakening of consensual decision-making in the Commons between the opening of the Short Parliament and December 1642. The political conflicts of these years were not able, in themselves, to topple the consensual tradition prevailing in Parliament, but some of them further revealed the conditions under which consensual decisions become increasingly infeasible. Divisions that did occur often involved ideological conflict, but ideological conflict was insufficient for causing majoritarian decisions. Instead, divisions in the House were overwhelmingly related to perceived threats to the honor, privilege, existence, or authority of the House of Commons, the Parliament as whole, or its members in particular. Conflicts over what course of action best conduced to maintaining the status of the House were what consistently led to divisions.
