Here we see Genghis’s not-so-nice behavior on display. His system was to surround a city and raise a white tent. If the people inside the city did not surrender by the end of the day, he put up the red tent, which meant that all men of fighting age would die. Allow another day to pass and Genghis would raise the black tent, telling the city that all living things were to be killed and the Mongols would begin attacking and razing the city. Not very surprisingly, northern China would lose as much as a third of its population by the time the Mongols were finished with the Jin Dynasty. In 1211, the Mongol troops met the main Jin army and when the day was done, half a million Chinese troops had been killed.
Genghis Khan may never have said the following quote, but it wouldn’t be so far off from his true personality:
The greatest joy for a man is to defeat his enemies, to drive them before him, to take from them all they possess, to see those they love in tears, to ride their horses, and to hold their wives and daughters in his arms.
