The work surveys constitutional tensions that produced conflict between king and Parliament, outlining early parliamentary crises, a prolonged period of royal personal government, and the convocation of Parliament that provokes impeachment, political fracture, and open rebellion. It follows the civil war through major campaigns and shifting alliances, describes the rise of competing religious and political factions and the army's increasing authority, and recounts the king's trial and execution and the proclamation of a republic. Later sections trace the commonwealth's military and naval efforts, experiments in republican and protectoral rule, social conditions, and the eventual disintegration of republican government leading to restoration.
