Just before Charles came to the throne, Parliament granted subsidies in expectation of a war against Spain, but, when he had used up the war- money without showing any serious inclination to open hostilities with Spain, and had then demanded additional grants, Parliament gave evidence of its growing distrust by limiting a levy of customs duties to one year, instead of granting them as usual for the whole reign. In view of the increasingly obstinate temper manifested by the House of Commons in withholding subsidies and in assailing his worthless favorite, the Duke of Buckingham, Charles angrily dissolved his first Parliament. [Sidenote: Continued Conflict between King and Parliament] [Sidenote: The Petition of Right, 1628] The difficulties of the administration were augmented not only by this arbitrary treatment of Parliament but also by the miserable failure of an English fleet sent against Cadiz, and by the humiliating result of an attempt to relieve the French Huguenots. Meanwhile, a second Parliament, more intractable even than its predecessor, had been dissolved for its insistence on the impeachment of Buckingham. Attempts to raise money by forced loans in place of taxes failed to remove the financial distress into which Charles had fallen, and consequently, in 1628, he consented to summon a third Parliament. In return for grants of subsidies, he signed the _Petition of Right_ (1628), prepared by the two houses. By it he promised not to levy taxes without consent of Parliament, not to quarter soldiers in private houses, not to establish martial law in time of peace, not to order arbitrary imprisonment. Even these concessions were not enough. Parliament again demanded the removal of Buckingham, and only the assassination of the unpopular minister obviated prolonged dispute on that matter. The Commoners next attempted to check the unauthorized collection of customs duties, which produced as much as one-fourth of the total royal revenue, and to prevent the introduction of "popish" innovations in religion, but for this trouble they were sent home. [Sidenote: "Personal" Rule of Charles I, 1629-1640] Charles was now so thoroughly disgusted with the members of Parliament that he determined to rule without them, and for eleven years (1629- 1640) he successfully carried on a "personal" as distinct from a parliamentary government, in spite of financial and religious difficulties.
