在第一次世界大战爆发之际，三位皇亲各自统治着欧洲的强大势力：沙俄帝国的沙皇尼古拉斯二世，德国的德皇威廉二世，以及英王乔治五世。这部两集纪录片系列检索了这三位君主在一战爆发中所起到的角色以及战争开始之际他们之间的关系；提论这些元素的影响要比以往的历史学家们所认识的要大的多。 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.
