The last Grand Prince of Moscow and first Tsar of Russia, Ivan IV's reign started on a promising note, with the conquest of the khanates of Kazan and Astrakhan, before taking a turn for the worst with the outbreak of the Livonian War and ending with self-harming actions like the Massacre of Novgorod and the killing of his son and heir, Ivan Ivanovich.
A good part of this decline can be owed to Ivan's growing paranoia and descent into madness, so what if he, among other things, didn't lose both of his parents at such a young age (Vasili III died when he was three years old, and Elena Glinskaya died when he was eight [and was just 27 years old at the time of her death])? How could having a saner and more reasonable Ivan IV affect Russia in the mid to late 16th century?
