With the collapse of Lord North's ministry in 1782, the Whig Lord Rockingham became Prime Minister for the second time but died within months. The King then appointed Lord Shelburne to replace him. Charles James Fox, however, refused to serve under Shelburne, and demanded the appointment of William Cavendish-Bentinck, 3rd Duke of Portland. In 1783, the House of Commons forced Shelburne from office and his government was replaced by the Fox–North Coalition. Portland became Prime Minister, with Fox and Lord North, as Foreign Secretary and Home Secretary respectively.
For George III, Pitt's appointment was a great victory. It proved that he was able to appoint Prime Ministers on the basis of his own interpretation of the public mood without having to follow the choice of the current majority in the House of Commons. Throughout Pitt's ministry, George supported many of Pitt's political aims and created new peers at an unprecedented rate to increase the number of Pitt's supporters in the House of Lords. During and after Pitt's ministry, George III was extremely popular in Britain. The British people admired him for his piety, and for remaining faithful to his wife. He was fond of his children, and was devastated at the death of two of his sons in infancy in 1782 and 1783 respectively. Nevertheless, he set his children a strict regimen. They were expected to attend rigorous lessons from seven in the morning, and to lead lives of religious observance and virtue. When his children strayed from George's own principles of righteousness, as his sons did as young adults, he was dismayed and disappointed.
