Li Renxiao was the eldest son of the Emperor Chongzong, and succeeded him at the age of sixteen. After ascending into the throne, Renzong made friendly overtures to the Jin dynasty. In domestic politics, Renzong created many schools and used examinations to choose his officials. He respected Confucianism, and built many temples worshipping Confucius. During the era of Tiansheng, Renzong hired a Tibetan lama as a religious advisor and printed many copies of Buddhist teachings.

In 1170, Renzong discovered a plot to kill him. He executed the generals who were behind the plot. As a result, Renzong distrusted his army generals and the army began to fall into incompetence. During his later years, Western Xia began to fight wars against various enemies.

Renzong's reign was the peak of Western Xia Dynasty. Many tribes to the north and west became vassal states of Western Xia, and Renzong's focus on internal politics allowed the central government to be more efficient. His reign coincides with the peak of the Southern Song and the Jin Dynasties, and there were relatively few conflicts between these three countries.

He died in 1193 having reigned for over half a century like his father before him.
