«This volume forms part of the Penguin Monarchs series, an impressive collection of short biographies written by renowned historians ... Their aim is not simply to summarise, but to offer genuine insights in accessible format. Black's analysis of George III is a welcome addition. [He] ... manages to pepper his trim narrative with lovely frills. The mark of a good short book is its ability to inspire curiosity and further investigation. Black achieves just that.»

Gerard DeGroot, The Times

«Black brilliantly demolishes the paranoiac Whig view of George as trying to accrete powers to himself unconstitutionally. The George who emerges is a far more attractive figure than the Whig historians depicted, let alone Thomas Jefferson with his 28 histrionic and inaccurate accusations against George in the Declaration of Independence, and especially Lin-Manuel Miranda's hilarious but profoundly historically incorrect caricature.»

Andrew Roberts, The Critic
