俄罗斯 空位时期  (1581年～1606年5月17日)

开端 终结 在位 1605年 1606年 

　　伪德米特里一世（1581年－1606年5月17日），俄罗斯沙皇，在外国势力支持下公开自称皇子德米特里·伊万诺维奇，自1605年6月1日起担任俄罗斯沙皇，死于1606年五月17日，历史上认为其冒充了伊凡雷帝（伊凡四世）最小的儿子—德米特里王子。

　　False Dmitriy I (Cyrillic Лжедмитрий; other transliterations:Dimitri, Dimitrii, Dimitriy, Dimitry, Dmitri, Dmitrii, Dmitry) was the Tsar of Russia from 21 July 1605 until his death on 17 May 1606 under the name of Dimitriy Ioannovich (Cyrillic Димитрий Иоаннович). He is sometimes referred to under the usurped title of Dmitriy II. He was one of three impostors who claimed during the Time of Troubles to be the youngest son of Ivan the Terrible, tsarevitch Dmitriy Ivanovich, who had supposedly escaped a 1591 assassination attempt. It is generally believed that the real Dmitriy was assassinated in Uglich and that this False Dmitriy's real name was Grigory Otrepyev, although this is far from certain.
