(1791–1801) as Foreign Secretary during the difficult period of the French Revolutionary Wars. Lord Grenville The resignation of Pitt's government in 1801 brought about a separation between Pitt and his cousin, William Wyndham Grenville (now Lord Grenville), which was encouraged by Buckingham and his followers, who had always resented Pitt for preventing him from receiving major office. During the Addington government from 1801 to 1804, a number of former supporters of the Pitt government declared their dissatisfaction with the new ministry, came to consider Grenville as their leader and called calling themselves "Grenvilles" or "Grenvillite". Although Grenville himself initially kept his distance from his supposed followers, he had by 1803 acknowledged himself as their leader. Other than dependents of Lord Buckingham, the group was largely former Portland Whigs who had joined the Pitt government in 1794 and opposed the Addington government's policy of peace with France. Notable members of the group included Lord Spencer, Lord Fitzwilliam, William Windham and Buckingham and Grenville's brother, Thomas Grenville. The new group, aptly nicknamed the "New Opposition", gradually made a tentative alliance with Charles James Fox's "Old Opposition". Their disagreements were many, most apparently on the topic of war with France, wherein the Grenvillites wished to prosecute it more aggressively, but Fox desired peace by negotiation. When Addington's government fell in 1804, Grenville hoped to form a coalition government that included supporters of himself, Pitt, and Fox, but he was stymied by the King's refusal to countenance a government that included Fox. Unwilling to go into government without his new ally, Grenville chose to remain in opposition when Pitt formed his second government in May of that year. When Pitt died two years later, however, the King had little choice but to appoint a government including both the "New" and "Old" Opposition, and Grenville became Prime Minister in the Ministry of All the Talents. Although the coalition partners agreed about little besides the abolition of the slave trade, it was really the King's opposition to the ministry that destroyed it in early 1807. Thereafter, Grenville acted as nominal Leader of the Opposition although Lord Grey, the leader of the Foxites, was essentially equal with him. Dissipation After Buckingham's death in 1813 and Grenville's withdrawal from politics in 1817, the Grenvillites remained a distinct political grouping in opposition, but they were by now little more than a pawn of the ambitions of Buckingham's son, the
