"best friend and the best of fathers ... I never had a [cross] word with him in my life. I am heart-broken and overwhelmed with grief". Edward has been recognised as the first truly constitutional British sovereign and the last sovereign to wield effective political power. Though lauded as "Peacemaker", he had been afraid that German Emperor Wilhelm II, who was one of his nephews, would tip Europe into war. Four years after Edward's death, the First World War broke out. The naval reforms he had supported and his part in securing the Triple Entente between Britain, France, and Russia, as well as his relationships with his extended family, fed the paranoia of the German Emperor, who blamed Edward for the war. Publication of the official biography of Edward was delayed until 1927 by its author, Sidney Lee, who feared German propagandists would select material to portray Edward as an anti-German warmonger. Lee was also hampered by the extensive destruction of Edward's personal papers; Edward had left orders that all his letters should be burned on his death. Subsequent biographers have been able to construct a more rounded picture of Edward by using material and sources that were unavailable to Lee. Historian R. C. K. Ensor, writing in 1936, praised the King's political personality: ...he had in many respects great natural ability. He knew how to be both dignified and charming; he had an excellent memory; and his tact in handling people was quite exceptional. He had a store of varied, though unsystematized, knowledge gathered at first-hand through talking to all sorts of eminent men. His tastes were not particularly elevated, but they were thoroughly English; and he showed much (though not unfailing) comprehension for the common instincts of the people over whom he reigned. This was not the less remarkable because, though a good linguist in French and German, he never learned to speak English without a German accent.

Ensor thought surviving documents showed "how comparatively crude his views on foreign policy were, how little he read, and of what naïve indiscretions he was capable." Edward received criticism for his apparent pursuit of self-indulgent pleasure, but he received great praise for his affable manners and
