Sentence (from "Ivan the Terrible"): Ivan is popularly believed to have killed his eldest son and heir Ivan Ivanovich and the latter's unborn son during his outbursts, which left the politically ineffectual Feodor Ivanovich to inherit the throne, a man whose rule directly led to the end of the Rurikid dynasty and the beginning of the Time of Troubles.
