What if the second man to impersonate the dead Dmitry, younger son of Ivan the Terrible succeeded in becoming Tsar of Russia. The so called rebel of Tushino, he had everything going for him, the previous pretender's wife claimed him to be the same man, many of the boyars supported him as well as Polish soldiers in his realm.
He had ammassed a massive army of over 120,000 soldiers (though many of his Polish soldiers decided to flee and join Sigismund III Vasa when the king arrived in Smolensk) and was besieging Moscow when a Tartar prince by the name of Peter Urusov, whom he had flogged, killed him while he was drunk and the entire thing disbanded.
Suppose he does not get murdered and does manage to capture Moscow. What happens next?
