Ögedei Khan died at the age of fifty-six after a binge of drinking during a hunting trip, which forced most of the Mongolian army to retreat back to Mongolia so that the princes of the blood could be present for the election of a new great khan. The Mongol forces retreat after receiving news of Ögedei Khan's death; Batu Khan stays at the Volga River and his brother Orda Khan returns to Mongolia. By mid-1242, the Mongols had completely withdrawn from Central Europe.
