How did Confucius change the earlier meaning of ren?

Prior to Confucius, the term ren was associated with aristocratic ideals, specifically referring to the physical handsomeness and bearing of a young, virtuous warrior.1

Confucius transformed this concept by shifting its focus from external social status or appearance to internal moral character. He redefined ren as the uprightness of the junzi, or cultured gentleman, who influences others toward ethical action through the example of his own excellence (de). Under this new definition, embodying ren does not require high social rank or eloquence; instead, it is achieved by embodying goodness in one's relationships with others and striving to become an ethically mature human being. By doing so, Confucius invested a term previously reserved for a specific noble class with a moral significance applicable to people generally.1
