Charles, now the king, convened the parliament again in 1625. The parliament did not give the king what the king wanted. The men in parliament did not like Charles's friend George Villiers, 1st Duke of Buckingham. Buckingham had gone with Charles to Spain and later helped him to marry Henrietta Maria. When Buckingham led the Royal Navy to attack Cadiz in Spain, the campaign was a failure, and the Parliament of England impeached him. Because of this, Charles stopped (dissolved) the parliament. He also wanted to send soldiers to help Protestants in the Kingdom of France, and made demands for more money as payment for the army. This campaign was also a failure, and the king had to agree to the Petition of Right in 1628. An army officer assassinated Buckingham that summer.
