Confucius was an influential Chinese philosopher, teacher and political figure known for his popular aphorisms and for his models of social interaction. Kong Qui, better known as Confucius, was born in 551 B.C. in the Lu state of China (near present-day Qufu). His teachings, preserved in the Analects, focused on creating ethical models of family and public interaction, and setting educational standards. He died in 479 B.C. Confucianism later became the official imperial philosophy of China, and was extremely influential during the Han, Tang and Song dynasties.
