Following the turbulent reign of Charles I, the question of succession became the central political crisis of the 17th century. The execution of the king in 1649 did not resolve the issue of legitimate authority; instead, it fractured the British state and forced a complex negotiation between republican experiment and the restoration of hereditary monarchy. Understanding the successor to Charles I requires navigating the competing claims of his son, the exiled court, and the powerful military regime that governed England.
The Immediate Heir: Charles, Prince of Wales
Charles I’s eldest son, Charles, Prince of Wales, was the undisputed dynastic heir. At the time of his father’s death in January 1649, the nineteen-year-old was in The Hague, coordinating a desperate royalist resistance from exile. Declaring himself King Charles II on 5 February 1649, he accepted the crown under the conditions of the Scottish Engagement, a pivotal moment that prioritized military alliance over religious conformity. His succession was a declaration of continuity, forcing the new Commonwealth to confront the reality of a living, breathing monarch who commanded loyalty from a significant portion of the three kingdoms.
The Recognition Crisis in Europe
One of the most significant challenges for the new king was securing international recognition. While Scotland quickly proclaimed him king, the English Republic and its allies hesitated. European powers like France and the United Provinces maintained a cautious neutrality, waiting to see if the Commonwealth could establish stable governance. Charles II’s legitimacy depended entirely on his ability to reclaim his father’s kingdoms, a task that would require both diplomatic maneuvering and military victory.
The Interregnum and the Cromwellian Alternative
For over a decade, the concept of a dynastic successor was violently contested. The Commonwealth period, often called the Interregnum, saw England function as a republic, first under the Rump Parliament and then under the Lord Protectorate. Oliver Cromwell, the dominant military figure, actively resisted the return of the Stuarts, viewing the monarchy as the root of civil strife. During this period, the "successor" was not a single heir but a political experiment, a vision of a godly republic that sought to erase the memory of Charles I’s failed reign.
The Humble Petition and Advice
The tension between republicanism and monarchy reached its peak during the period of the Humble Petition and Advice in 1657. This constitutional document effectively offered Cromwell the crown, a direct challenge to the principle of succession established by Charles I’s execution. Cromwell’s refusal to become king, despite accepting near-royal powers, highlights the enduring power of hereditary legitimacy. The document proved that the nation was still divided on the form of government, with the ghost of the executed king lingering over every debate.
The Restoration: Charles II Ascendant
The death of Oliver Cromwell in 1658 and the subsequent collapse of the Protectorate created a power vacuum that the restored monarchy was uniquely positioned to fill. In 1660, a weary nation invited Charles II to return, framing his succession not as a conquest but as a restoration of order. The political gamble succeeded; the new king, adhering to the advice of his chancellor Edward Hyde, adopted a policy of conciliation, emphasizing his role as a unifying father figure rather than a vengeful monarch. This careful navigation allowed the monarchy to reassert itself, learning from the mistakes of its predecessor.
Legal and Legitimate Continuity
Charles II’s reign was built on the legal principle of the "Act of Free and General Pardon, Indemnity, and Oblivion." While many regicides were punished, the king ultimately accepted that his rule derived from the consent of the people and the Convention Parliament, rather than a simple reclaiming of his birthright. This nuanced approach allowed the successor to distance the restored monarchy from the absolutist tendencies of Charles I, creating a more flexible and resilient constitutional framework that would define the British state for centuries.
