Qin Dynasty and the Warring States

I've linked to Historical about the Qin Dynasty and Warring States in China. This is the period which Hero takes place. I linked to wikipedia but because its information is still up for review I also liked to Britannica Encyclopedia (LINK BELOW). The Warring States Period was a time in China's history when the country was divided into six or seven smaller kingdoms all competing for leadership in China. In the Film Hero, there are assassins from these different kingdoms trying to kill the leader of the Qin Dynasty. Historically, it is the Qin Dynasty who unifies China in 221 B.C.
