How did Ivan the Terrible (czar of Russia) die?
Although it is thought by many that Ivan died while setting up a chess board, it is more likely that he died while playing chess with Bogdan Belsky on March 18, 1584. When Ivan’s tomb was opened during renovations in the 1960s, his remains were examined and discovered to contain very high amounts of mercury, indicating a high probability that he was poisoned. Modern suspicion falls on his advisors Belsky and Boris Godunov (who became tsar in 1598). Three days earlier, Ivan had allegedly attempted to rape Irina, Godunov’s sister and Feodor’s wife. Her cries attracted Godunov and Belsky to the noise, whereupon Ivan let Irina go, but Belsky and Godunov considered themselves marked for death. The tradition says that they either poisoned or strangled Ivan in fear for their own lives. Upon Ivan’s death, the ravaged kingdom was left to his unfit and childless son Feodor.
