The eleven years 1629–1640, during which Charles ruled England without a Parliament, are referred to as the Personal Rule. There was no money for war so peace was essential. Without the means in the foreseeable future to raise funds from Parliament for a European war, or the help of Buckingham, Charles made peace with France and Spain. Lack of funds for war, and internal conflict between the king and Parliament led to a redirection of English involvement in European affairs – much to the dismay of Protestant forces on the continent. This involved a continued reliance on the Anglo-Dutch brigade as the main agency of English military participation against the Habsburgs, although regiments also fought for Sweden thereafter. The determination of James I and Charles I to avoid involvement in the continental conflict appears in retrospect as one of the most significant, and most positive, aspects of their reigns. There was a small naval Anglo-French War (1627–1629), in which the England supported the French Huguenots against King Louis XIII of France.
