 Sun Tzu ( pinyin : Sun Zi ; c . 544 BC — 496 BC ) was a native of the Qi state ( now Huimin county in Shandong ) during the Spring and Autumn Period of Chinese history , that was characterised by warring factions and a fragmented state . He came to the attention of King He Lu of Wu , who was impressed by his 13 @-@ chapter military treatise , The Art of War . In 512 BC , He Lu made Sun Tzu his Commander @-@ in @-@ Chief of the Wu army . For almost 20 years , the armies of Wu were victorious over their hereditary enemies , the kingdoms of Chu and Yue . In 496 BC , after He Lu died from his wounds in battle , his son , Fu Chai succeeded him . After numerous victories in battles , Fu Chai became arrogant and began to indulge in merrymaking . In time , the king started to disregard Sun Tzu 's counsel and began to distance himself from Sun Tzu . Sensing this , Sun Tzu wisely gave up his position and left Wu for Qi in retirement . Fu Chai and his generals did not follow Sun Tzu 's precepts and his kingdom was subsequently conquered by Chu in 473 BC . Out of shame , Fu Chai committed suicide after he had fled with the remnants of his defeated army .
