In November of 1581, the first Czar of Russia, Ivan Vasilyevich, a man who conquered, killed, and terrified, and ruled for 40 years, took offense at the skimpy clothes of his pregnant daughter-in-law, Elena, and beat her for it.
The czar’s 27-year-old son, Ivan Ivanovich, rushed in and confronted his father, who struck him violently with a pointed scepter. The blow punctured the prince’s skull, and he died 3 days later.
Elena soon miscarried the czar’s grandchild.
A single egoic injury, a slight loss of the great czar’s perceived control (his daughter-in-law’s impudent attire), caused Ivan to kill not just one future king, but possibly two.
