Battle of Chang'an
So, a long, long time ago in China, there was a big fight between two groups of people. One group was called the Tang Dynasty and the other group was called the rebel army. They both wanted to be in charge of China.
The fight happened in a city called Chang'an. The Tang Dynasty was living there and the rebel army came to attack them. The fight was very intense and many people were hurt.
The Tang Dynasty had a very strong army, but the rebel army was very sneaky. They pretended to leave the city, but then they sneaked back in and attacked the Tang Dynasty again. This trick worked and the rebel army won the fight.
After the fight, the Tang Dynasty ran away and the rebel army became in charge of Chang'an and China. The rebel army leader, Li Shimin, became the emperor and started a new dynasty called the Tang Dynasty.
So, basically, the Battle of Chang'an was a fight between two groups of people who wanted to rule China. The rebel army won and started a new dynasty.
