Background and detail

Strategic Context. Following initial Swedish successes, Charles XII invaded Russia in 1707. After the harsh winter of 1708–1709, his weakened forces besieged the fortress of Poltava in May 1709, prompting a Russian relief effort.

Decisive Victory. The Russian army, commanded by Peter I, defeated the Swedish forces under Carl Gustaf Rehnskiöld. This victory marked the greatest military catastrophe in Swedish history and shifted the balance of power in the Baltic region to Russia.
