George, Roberts writes, “more than filled the role of King of Great Britain worthily; he filled it nobly”. After reading this mammoth, elegant and splendidly researched biography, no open-minded reader could possibly disagree – not even an American.

‘Andrew Roberts is our most prodigious biographer … His demolition of the authors of the Declaration’s case against George III is elegant and comprehensive.

Magisterial … George III is notorious for two reasons: losing America and going mad. Roberts provides a fresh and spirited account of both occurrences … Roberts’s fundamentally humane approach to his biographical subjects … treats George III with as much respect and compassion when sick, blind and deaf as when powerful at the promising start of his reign. The result is a lengthy book that remains engaging throughout.

powerful … a very fine book … This book should be read by every American whose interest in history goes beyond the feel-good. It is challenging, but richly evidenced and scrupulously argued. … Coming after his powerful studies of Halifax, Salisbury, Napoleon and Churchill, it consolidates Roberts’s position as one of the greatest biographers in the English language today.

If not for such fierce competition (in the form of such works as Salisbury: Victorian Titan, Churchill: Walking with Destiny and Masters & Commanders) one might be able to unequivocally say that George III is the author’s masterpiece. This biography teems with detail, ideas and elegance. Roberts is a great writer – and this is one of his greatest achievements. Roberts sets himself a goal, that of challenging or overturning certain misconceptions that we might harbour about his subject. That George III was a tyrant, unintelligent and a victim of porphyria. Suffice to say, Roberts achieves his goal: mission impossible turns into mission accomplished. Roberts convinces through both persuasive prose and hard evidence (as opposed to just supposition). … magnificent

George may become Britain’s best-understood monarch, thanks to this impressive new biography. It is unashamedly revisionist. … Roberts’s account is masterly, combining a compelling narrative – one has to keep turning the pages even though one knows the outcome – with analysis that is both cogent and incisive. He appears to have read everything that is in the mainstream and much that isn’t, including a wide range of archival sources. … [George III] has had to wait two centuries for rehabilitation, but it has come at last. Roberts has got deep inside George and his world and has found a man of many sterling qualities. … tremendous

In this magisterial life of George III, Roberts burnishes his stellar reputation as biographer and historian, dismantling many of the myths that have beset the memory of the man who ruled Britain and Ireland for almost sixty years from 1760. Roberts marshals the evidence meticulously and persuasively to show that George was nothing like the capricious, overbearing, intolerable figure of legend … It is bracing, too, to see that Roberts has lost none of his disdain for the “Whig interpretation of history” – the comfort blanket of those who believe that Britain’s story is one of the steady institutional defeat of autocracy by liberal incrementalism. Now at the top of his game, he has not surrendered the irreverent, revisionist tone that has made him one of the most important public intellectuals of our times.

This superb royal biography … A book so diligently researched cannot fail to be rich in curious detail and amusing turns of phrase. There are plums on almost every page.

The strength of this generous new biography is that it correctly portrays George III as a dedicated, benevolent ruler , scrupulous in his constitutional role as head of government and head of state.

Andrew Roberts admires George III, and he is right to do so. The historical image of the king as a tyrant and a lunatic is not remotely true in the first case (a contention Roberts provides much evidence to substantiate) and true only for part of his reign in the second. … A handsome and thorough biography … but above all, Roberts has written a superlative political history of the period between 1760 and 1809.
