Shelburne's new military role close to the King brought him into communication with
Lord Bute, who was the King's closest advisor and a senior minister in the government. In 1761 Shelburne was employed by Bute to negotiate for the support of
Henry Fox. Fox held the lucrative but unimportant post of
Paymaster of the Forces, but commanded large support in the House of Commons and could boost Bute's power base. Shelburne was opposed to Pitt, who had resigned from the government in 1761. Under instructions from Shelburne, Barré made a vehement attack on Pitt in the House of Commons. In 1762 negotiations for a peace agreement went on in London and Paris. Eventually, a deal was agreed but it was heavily criticised for the perceived leniency of its terms as it handed back a number of captured territories to France and Spain. Defending it in the House of Lords, Shelburne observed "the security of the British colonies in North America was the first cause of the war" asserting that security "has been wisely attended to in the negotiations for peace". Led by Fox, the government was able to push the peace treaty through parliament despite opposition led by Pitt. Shortly afterwards, Bute chose to resign as prime minister and retire from politics and was replaced by
George Grenville. Shelburne joined the
Grenville ministry in 1763 as
First Lord of Trade. By this stage, Shelburne had changed his opinion of Pitt and become an admirer of him. After failing to secure Pitt's inclusion in the Cabinet he resigned office after only a few months. Having moreover on account of his support of Pitt on the question of
John Wilkes's expulsion from the House of Commons incurred the displeasure of the King, he retired for a time to his estate.
Southern Secretary After Pitt's return to power in 1766, he became
Southern Secretary, but during Pitt's illness his conciliatory policy towards America was completely thwarted by his colleagues and the King, and in 1768 he was dismissed from office. During the
Corsican Crisis, sparked by the
French invasion of Corsica, Shelburne was the major voice in the cabinet who favoured assisting the
Corsican Republic. Although secret aid was given to the Corsicans it was decided not to intervene militarily and provoke a war with France, a decision made easier by the departure of the hard-line Shelburne from the cabinet. In June 1768 the General Court incorporated the district of
Shelburne, Massachusetts from the area formerly known as "Deerfield Northeast" and in 1786 the district became a town. The town was named in honour of Lord Shelburne, who, in return sent a
church bell, which never reached the town.
Opposition Shelburne went into Opposition where he continued to associate with
William Pitt, 1st Earl of Chatham. They were both critical of the policies of the
North government in the years leading up to the outbreak of the
American War of Independence in 1775. As the war progressed, Shelburne cooperated with the
Rockingham Whigs to attack the government of Lord North. After a British army was compelled to surrender at the
Battle of Saratoga in 1777, Shelburne joined other leaders of the Opposition to call for a total withdrawal of British troops. ==Prime minister==
