George I was not the most charismatic of the Hanoverian monarchs to have reigned in England but he was probably the most important. He was certainly the luckiest. Born the youngest son of a landless German duke, he was taken by repeated strokes of good fortune to become, first the ruler of a major state in the Holy Roman Empire of the German Nation and then the sovereign of three kingdoms (England, Ireland and Scotland). Tim Blanning’s incisive short biography examines George’s life and career as a German prince, and as King. Fifty-four years old when he arrived in London in 1714, he was a battle-hardened veteran, who put his long experience and deep knowledge of international affairs to good use in promoting the interests of both Hanover and Great Britain. When he died, his legacy was order and prosperity at home and power and prestige abroad. Disagreeable he may have been to many, but he was also tough, determined and effective, at a time when other European thrones had started to crumble.
