在第一次世界大戰爆發之際，三位皇親各自統治著歐洲的強大權勢：沙俄帝國的沙皇尼古拉斯二世，德國的德皇威廉二世，以及英王喬治五世。這部兩集紀錄片系列檢索了這三位君主在一戰爆發中所起到的角色以及戰爭開始之際他們之間的關系；提論這些元素的影響要比以往的汗青學家們所認識的要大的多。　　At the outbreak of the First World War three cousins reigned over Europe's greatest powers - Tsar Nicholas II of Russia, Kaiser Wilhelm II of Germany and King George V of England. This two-part series looks at the role played by the three monarchs, and their relationships with each other, in the outbreak of war, arguing that it is far greater than historians have traditionally believed.
