The Analects, or Lunyu (literally "Selected Sayings"), also known as the Analects of Confucius, is the collection of sayings and ideas attributed to the Chinese philosopher Confucius and his contemporaries, traditionally believed to have been written by Confucius' followers. It is believed to have been written during the Warring States period (475 BC - 221 BC), and it achieved its final form during the mid-Han dynasty (206 BC-220 AD). The Analects has been one of the most widely read and studied books in China for the last 2,000 years, and continues to have a substantial influence on Chinese and East Asian thought and values today. Confucius (551-479 BCE) was a Chinese teacher, editor, politician, and philosopher of the Spring and Autumn Period of Chinese history. The philosophy of Confucius emphasized personal and governmental morality, correctness of social relationships, justice and sincerity. His followers competed successfully with many other schools during the Hundred Schools of Thought era only to be suppressed in favor of the Legalists during the Qin Dynasty. Following the victory of Han over Chu after the collapse of Qin, Confucius's thoughts received official sanction and were further developed into a system known as Confucianism.
