Wilhelm von Habsburg wore the uniform of an Austrian officer, the court regalia of a Habsburg archduke, the simple suit of a Parisian exile, the decorations of the Order of the Golden Fleece and, every so often, a dress. He spoke the Italian of his archduke mother, the German of his archduke father, the English of his British royal friends, the Polish of the country his father wished to rule and the Ukrainian of the land Wilhelm wished to rule himself. Timothy Snyder's masterful biography is not only a reconstruction of the life of this extraordinary man – a man who remained loyal to his Ukrainian dreams even after the country's dissolution in 1921– but also charts the final collapse of the ancien regime in Europe and the rise of a new world order.
