Christopher Clark's "Kaiser Wilhelm II: A Life in Power" is a short, fascinating
 and accessible biography of one of the 20th century's most important figures. K
ing of Prussia, German Emperor, war leader and defeated exile, Kaiser Wilhelm II
 was one of the most important - and most controversial - figures in the history
 of twentieth-century Europe. But how much power did he really have? Christopher
 Clark, winner of the Wolfson prize for his history of Prussia, Iron Kingdom, fo
llows Kaiser Wilhelm's political career from his youth at the Hohenzollern court
 through the turbulent decades of the Wilhelmine era into global war and the col
lapse of Germany in 1918, to his last days.
