When He Took Over The Throne
At the tender age of 13, Qin Shi Huang ascended the throne. He then worked on a huge mausoleum that would serve as his final resting place and a testament to his own power. As always, not everyone had been a big fan of this new ruler. Even back then, there was no getting around political conflict.
The Warring States
Qin Shi Huang might get credit for the unison of the warring states, but it was not a peaceful process. In fact, it involved conquest and bloodshed. You would think that he would be able to rest easy after the death of his enemies, but he feared that they would come back to exact revenge on him in the next life.
