Crown Prince Dan
Appearance
Crown Prince Dan of Yan (Chinese: 燕太子丹) was a crown prince of the state of Yan during the Warring States Period in China. He sent Jing Ke to assassinate Qin Shi Huang, then Emperor of China, but he failed. King Xi of Yan, Dan's father and the last king of Yan, ordered the execution of Dan to please the Qin after Ji, the capital of Yan, had fallen [1]. Invasion of Qin did halt for few years, during which time the states of Wei and Chu were conquered. Meanwhile the King Xi of Yan moved to the Liaodong Commandery.
The state of Yan was conquered in 222 BC and King Xi was captured.
All except King Xi were featured in the Chinese period epic The Emperor and the Assassin
(Was this period still of the Zhou dynasty?)
