I am Emperor Taizong of Tang, I was the second emperor of the Tang dynasty of China, ruling from 626 to 649. I was traditionally regarded as a co-founder of the dynasty for my role in encouraging my father Li Yuan (Emperor Gaozu) to rebel against the Sui dynasty at Jinyang in 617. I subsequently played a pivotal role in defeating several of the dynasty's most dangerous opponents and solidifying its rule over China proper.
