The Peace of Pressburg was signed in Pressburg on 26 December 1805 between French Emperor Napoleon Bonaparte and Holy Roman Emperor Francis II, as a consequence of the French victory over the Russians and Austrians at the Battle of Austerlitz. A truce was agreed on 4 December, and negotiations for the treaty began. The treaty was signed by Johann I Joseph, Prince of Liechtenstein, and the Hungarian Count Ignác Gyulay for the Austrian Empire and Charles Maurice de Talleyrand for France.
