Yuan Shao was a powerful warlord during the late Eastern Han Dynasty and Three Kingdoms era of China. He occupied the northern territories of ancient China during the massive civil war towards the end of the Eastern Han Dynasty and the beginning of the Three Kingdoms era. He was also the elder brother of Yuan Shu, a warlord who controlled the Huai River region, though the two were not in good terms with each other. One of the most powerful warlords of his time, Yuan Shao spearheaded a coalition of warlords against the tyrannical Dong Zhuo, who held Emperor Xian hostage in the capital Luo Yang, but failed due to internal disunity. In 200, he launched a campaign against rival warlord Cao Cao but was decisively defeated at the Battle of Guan Du. He died of sickness two years later in Ye. His eventual failure despite his powerful family background and geographical advantages was commonly blamed on his indecisiveness and inability to heed the advice of his advisors.
