In the 13th century, the lands under the control of the Mongol Empire extended from the Adriatic and the Mediterranean in the west to the southern regions of China in the east. However, even within its vast territories, there were regions that did not bow to the Genghis Dynasty, one of which was the city of Kozelsk. The Mongol army had bypassed the high walls of this small city, but the hatred a commander harbored against the city's people forced Kozelsk to fight against the world's most powerful army.
