Bohemian Succession War
(1545 - 1547)
(1545 - 1547)
On 16th November 1544 King Jiri of Bohemia died without Heirs, causing a succession crisis. While the Bohemian nobility favored one of their own as new King, Emperor Maximilian I wanted a member of the Habsburg dynasty on the throne in order to increase control over one of the seven Electors. Finally the Polish-Lithuanian King August IV von Mecklenburg supported the claim of his nephew Albert.
Eventually the Bohemian elite elected one of its leaders, Vaclav V Podebrad, as new King. In the aftermath, August IV raised claims on Bohemian territory and declared war on Vaclav in early 1545. While Poland-Lithuania was supported by Moldavia, Bohemia was backed by Istvan VI, King of Hungary, and the Emperor Maximilian I.
Tsar Vasily III closely followed the events in the west. Poland-Lithuania was his most powerful rival and further conquests at the expense of Bohemia might have changed the already fragile balance of power in Poland`s favor. So Vasily declared war on Poland-Lithuania too.
Faced with a two-front war, Poland-Lithuania was immediately outnumbered. The combined Bohemian-Austrian forces marched into Polish core territories, while Hungary eliminated the Moldavian force. In the east, the Russian armies crossed the borders and besieged the important fortresses of Bryansk and Lipetsk, which fell in 1546 and 1547. Also in 1547, the fortress of Poltava was conquered.
In the outskirts of Poltava, the decisive battle was fought on 4th September 1547. Although the Polish-Lithuanian army consisted of only roughly 40.000 soldiers compared to roughly 70.000 Russians, they almost won the battle, until suddenly the Polish right flank collapsed under a final massive Russian infantry assault. Poltava proved the already important status of firearms and cannons on the battlefield, with which the Polish army was better equipped. The Russian force had inferior equipment, but could make up for it by superior numbers.

After Poltava, the Polish army had ceased to exist as efficient fighting force and August IV had to call for negotiations. In the Treaty of Buda of 1547 he had to cede vast territories to his enemies. Bohemia received Polish territories reaching from Poznan to Krakow, Hungary the west of Moldavia. Eventually Russia gained Vitebsk and the fortress of Lipetsk as well as minor territories in the south.
At the end of the day, the Bohemian Succession War was a huge failure for Poland and caused the long-term enmity between Poland and Russia.
