Frederick the Great, King of Prussia, dominated the eighteenth century in the same way that Napoleon dominated the start of the nineteenth. He was a force of nature, a ruthless, brilliant, charismatic military commander, a monarch of exceptional energy and talent, a gifted composer, performer, poet and philosopher, and a discerning patron of artists, architects and writers, most famously Voltaire. From the very start of his reign he was an intensely divisive figure  fascinating even to those who hated him. Tim Blanning's brilliant new biography captures Frederick's vitality, complexity and flawed genius better than any previous writer. He also recreates a remarkable era, the last flowering of the old regime that would be swept away almost immediately after Frederick's death by the French Revolution. Equally at home on the battlefield or in the music room at Frederick's extraordinary miniature palace of Sanssouci, Blanning draws on a lifetime's immersion in the eighteenth century to present him in the round, with new attention paid to his cultural self-fashioning, including his sexuality. Frederick's spectre has hung over Germany ever since, both as inspiration and warning. Blanning at last allows us to understand him in his own time.
