During most of the Han period the "Analects" was not considered one of the principal texts of Confucianism. During the reign of Han Wudi (141–87 BC), when the Chinese government began promoting Confucian studies, only the Five Classics were considered by the government to be canonical ("jing"). They were considered Confucian because Confucius was assumed to have partially written, edited, and/or transmitted them. The "Analects" was considered secondary as it was thought to be merely a collection of Confucius's oral "commentary" ("zhuan") on the Five Classics.
