The significant battle that took place during the peak of Napoleon’s military campaigns was the Battle of Austerlitz, fought on December 2, 1805. Often termed the Battle of the Three Emperors, it pitted Napoleon’s French forces against the combined armies of Russia and Austria. The French victory at Austerlitz is seen as one of Napoleon's greatest tactical triumphs, demonstrating his military genius. The defeat of the Coalition forces not only solidified Napoleon's control over much of Europe but also led to the Treaty of Pressburg, dramatically changing the geopolitical landscape of continental Europe.
