Who was King of England during the Seven Years' War?
August de la Motte
De la Motte was born on 17 November 1713 in the Principality of Brunswick-Wolfenbüttel. He served in the Hanoverian Army during the Seven Years' War, notably participating in the Second Siege of Cassel. In 1775 the Duke and Prince-elector of Hanover was George III, who also ruled the Kingdom of Great Britain in personal union. King George had to deal with the American Revolution and the outbreaking American Revolutionary War and prepared to ready Hanoverian troops for garrison duty so that British troops would be freed for service in America.
Great Britain in the Seven Years' War
Britain found itself bound by the Westminster Convention and entered the war on the Prussian side. Newcastle was deeply reluctant to do this, but he saw that a Prussian collapse would be disastrous to British and Hanoverian interests. The Anglo-Prussian Alliance was established, which saw large amounts of subsidy given to Prussia. Some supporters of George II were strong advocates of support for Prussia, as they saw it would be impossible to defend his realm of Hanover if they were to be defeated. Despite his initial dislike of Frederick, the King later moved towards this viewpoint.
