而吴王夫差盲目力图争霸，丝毫不考虑民生疾苦。他还听信伯嚭的坏话，杀了忠臣伍子胥。最终夫差争霸成功，称霸于诸侯。但是这时的吴国，貌似强大，实际上已经是走下坡路了。
公元前482年，夫差亲自带领大军北上，与晋国争夺诸侯盟主，越王勾践趁吴国精兵在外，突然袭击，一举打败吴兵，杀了太子友。夫差听到这个消息后，急忙带兵回国，并派人向勾践求和。勾践估计一下子灭不了吴国，就同意了。公元前473年，勾践第二次亲自带兵攻打吴国。这时的吴国已经是强弩之末，根本抵挡不住越国军队的强势猛攻，屡战屡败。最后，夫差又派人向勾践求和，范蠡坚决主张要灭掉吴国。夫差见求和不成，才后悔没有听伍子胥的忠告，非常羞愧，就拔剑自杀了。
