The Battle of Lake Peipus took place on April 5, 1242, between the forces of the Teutonic Knights and the Novgorod Republic. This conflict was part of the larger struggle for control over the Baltic region. The battle is notable for its icy setting, as it occurred on the frozen surface of Lake Peipus, allowing for a unique tactical environment. Led by Prince Alexander Nevsky, the Novgorod forces achieved a decisive victory against the heavily armored knights. This battle significantly weakened the influence of the Teutonic Order in the region and bolstered Novgorod's power, marking a pivotal moment in the history of medieval Russia and the Baltic states.
