The Battle of Austerlitz (December 2, 1805) was a famous battle in the Napoleonic Wars. The 75,000 French army, under the command of Napoleon, achieved a decisive victory over 87,000 Russian-Austrian forces in the village of Austerlitz in Bohemia (located in present-day Czech Republic). The third anti-French alliance collapsed and the Austrian emperor was forced to cancel the title of the Holy Roman Emperor the following year.
This battle was due to the presence of Emperor Franz II, Tsar Alexander I, and Emperor Napoleon of the First French Empire from the three major European countries. It is also known as the "War of the Three Emperors".
