So the battle of the Vorksla river was a somewhat influential in the history of Eastern Europe battle, where the forces of Lithuania, Poland, Moldavia, Wallachia and Teutonic Order led by Grand Duke Vytautas and Tatars led by Tokhtamysh fought against the army of the Golden Horde, led by Edigu and Temur Qutlugh.
The battle was a part of the Grand Dukes Vytautas expedition to put Khan Tokhtamysh as the leader of the Golden Horde. The Khan promised Vytautas that if the expedition is succesful he will surrender suzerainty over the Ruthenian lands.
Vytautas and Tokhtamysh lost the fateful battle at Vorksla, but what if they had won?
How would such an event change Eastern Europe?
