From the author of The Romanovs: a vivid account of history's most successful political partnership—as sensual and fiery as it was creative and visionary. Catherine the Great was a woman of notorious passion and imperial ambition. Prince Potemkin—wildly flamboyant and sublimely talented—was the love of her life and her co-ruler.Together they seized Ukraine and Crimea, territories that define the Russian sphere of influence to this day. Their affair was so tumultuous that they negotiated an arrangement to share power, leaving each of them free to take younger lovers. But these “twin souls” never stopped loving each other.Drawing on the pair’s intimate letters and on vast research, Simon Sebag Montefiore's widely acclaimed biography restores these imperial partners to their rightful place as titans of their age.
