Daming Lake
During the Civil War that followed the proclamation of Kublai Khan as Great Khan in 1260 CE, Jinan was at the center of a rebellion by Yizhou governor Li Tan against Mongol rule in 1262 CE. The rebellion was crushed in a decisive battle that was fought not far from Jinan in late March or early April 1262 CE. After losing 4000 of his troops in the battle, Li Tan retreated to Jinan to make his last stand. After defections of his defenders had made his position untenable, Li Tan tried to commit suicide by drowning himself in Daming Lake. However, he was rescued by the Mongols in order to execute him by trampling him to death with their horses.
