The clamour for ‘a free parliament’ in the winter of 1659–60, the most widely articulated public demand since the outbreak of civil war, has not received attention proportionate to its significance. Here the contours and chronology of the movement are reconstructed. Its goal was the summoning of an assembly which, through the restoration of parliamentary representation and the emancipation of the electorate from voting restrictions and military interference, would possess the authority to speak for the nation and secure a national settlement. The outcome was that essential instrument in the peaceful return of the monarchy, the Convention. The term ‘a free parliament’ was a slogan, used for a variety of political ends. Yet it was a unifying phrase which allowed the two parties opposed to the republic, the royalists (who had been denied parliamentary representation in 1642) and the presbyterians (who had been forcibly removed from parliament in 1648) to suspend their differences. The movement also connected national politicians of both parties to intense grievances in the regions. Local sentiment was voiced in a cascade of manifestos, published in the names of counties and towns, which illustrate the hold of parliament on public feeling.
