The policy was supported by the Howards and other Catholic-leaning ministers and diplomats—together known as the Spanish Party—but deeply distrusted in Protestant England. When Sir Walter Raleigh was released from imprisonment in 1616, he embarked on a hunt for gold in South America with strict instructions from James not to engage the Spanish. Raleigh's expedition was a disastrous failure, and his son Walter was killed fighting the Spanish. On Raleigh's return to England, James had him executed to the indignation of the public, who opposed the appeasement of Spain. James's policy was further jeopardised by the outbreak of the Thirty Years' War, especially after his Protestant son-in-law, Frederick V, Elector Palatine, was ousted from Bohemia by the Catholic Emperor Ferdinand II in 1620, and Spanish troops simultaneously invaded Frederick's Rhineland home territory. Matters came to a head when James finally called a Parliament in 1621 to fund a military expedition in support of his son-in-law. The Commons on the one hand granted subsidies inadequate to finance serious military operations in aid of Frederick, and on the other—remembering the profits gained under Elizabeth by naval attacks on Spanish gold shipments—called for a war directly against Spain. In November 1621, roused by Sir Edward Coke, they framed a petition asking not only for war with Spain but also for Prince Charles to marry a Protestant, and for enforcement of the anti-Catholic laws. James flatly told them not to interfere in matters of royal prerogative or they would risk punishment, which provoked them into issuing a statement protesting their rights, including freedom of speech. Urged on by the Duke of Buckingham and the Spanish ambassador Gondomar, James ripped the protest out of the record book and dissolved Parliament.
