He was expelled from states many times and eventually returned to his homeland to spend the last part of his life teaching. The Analects of Confucius, the closest primary source we have for his thoughts, relates his sayings and discussions with rulers and disciples in short passages.

Confucianism as passed down to the 19th and 20th centuries derives primarily from the school of the Neo-Confucians, led by Zhu Xi, who gave Confucianism renewed vigor in the Song and later dynasties.
