According to my essay at: http://www.religioustolerance.org/confuciu.htm
"K'ung Fu Tzu (commonly pronounced Confucius in English) was born in 551 BCE in the state of Lu (modern day Shantung Province). He lived during the Chou dynasty, an era known for its moral laxity. Later in life, he wandered through many states of China, giving advice to their rulers. He accumulated a small band of students during this time. The last years of his life were spent back in Lu, where he devoted himself to teaching. He died about 479 BCE at the approximate age of 72."
