Yuan Shu () (155 – 199), courtesy name Gonglu, was a Chinese military general, politician, and warlord who lived during the late Eastern Han dynasty. He rose to prominence following the collapse of the Han central government in 189. He declared himself Emperor of China in 197 under the short-lived Zhong dynasty, two years before his death in 199.
Yuan Shao (袁紹, ; died 28 June 202), courtesy name Benchu (本初), was a Chinese military general, politician, and warlord who lived in the late Eastern Han dynasty. He occupied the northern territories of China during the civil wars that occurred towards the end of the Han dynasty. He was also an elder half-brother of Yuan Shu, a warlord who controlled the Huai River region, though the two were not on good terms with each other.
One of the most powerful warlords of his time, Yuan Shao spearheaded a coalition of warlords against Dong Zhuo, who held Emperor Xian hostage in the imperial capital, Luoyang, but failed due to internal disunity. In 200, he launched a campaign against his rival Cao Cao but was defeated at the Battle of Guandu. He died of illness two years later in Ye. His eventual failure despite his illustrious family background and geographical advantages was commonly blamed on his indecisiveness and inability to heed the advice of his advisors.
Cao Cao (; [tsʰǎʊ tsʰáʊ]; Chinese: 曹操; c. 155 – 15 March 220), courtesy name Mengde, was a Chinese statesman, warlord, and poet who rose to power during the end of the Han dynasty (c. 184–220), ultimately taking effective control of the Han central government. He laid the foundation for the state of Cao Wei (220–265), established by his son and successor Cao Pi, who ended the Eastern Han dynasty and inaugurated the Three Kingdoms period (220–280). Beginning in his own lifetime, a corpus of legends developed around Cao Cao which built upon his talent, his cruelty, and his perceived eccentricities.
Cao Cao began his career as an official under the Han government and held various appointments including that of a district security chief in the capital and the chancellor of a principality. He rose to prominence in the 190s during which he recruited his own followers, formed his own army, and set up a base in Yan Province (covering parts of present-day Henan and Shandong). In 196, he received Emperor Xian, the figurehead Han sovereign who was previously held hostage by other warlords such as Dong Zhuo, Li Jue, and Guo Si. After he established the new imperial capital in Xuchang, Emperor Xian and the central government came under his direct control, but he still paid nominal allegiance to the emperor. Throughout the 190s, Cao Cao actively waged wars in central China against rival warlords such as Lü Bu, Yuan Shu, and Zhang Xiu, eliminating all of them. Following his triumph over the warlord Yuan Shao at the Battle of Guandu in 200, Cao Cao launched a series of campaigns against Yuan Shao's sons and allies over the following seven years, defeated them, and unified much of northern China under his control. In 208, shortly after Emperor Xian appointed him as Imperial Chancellor, he embarked on an expedition to gain a foothold in southern China, but was defeated by the allied forces of the warlords Sun Quan, Liu Bei, and Liu Qi at the decisive Battle of Red Cliffs.
Lü Bu (; died 7 February 199), courtesy name Fengxian, was a Chinese military general, politician, and warlord who lived during the late Eastern Han dynasty of Imperial China. Originally a subordinate of a minor warlord Ding Yuan, he betrayed and murdered Ding Yuan and defected to Dong Zhuo, the warlord who controlled the Han central government in the early 190s. In 192, he turned against Dong Zhuo and killed him after being instigated by Wang Yun and Shisun Rui (士孙瑞), but was later defeated and driven away by Dong Zhuo's followers.
From 192 to early 195, Lü Bu wandered around central and northern China, consecutively seeking shelter under warlords such as Yuan Shu, Yuan Shao, and Zhang Yang. In 194, he managed to take control of Yan Province from the warlord Cao Cao with help from defectors from Cao's side, but Cao took back his territories within two years. In 195, Lü Bu turned against Liu Bei, who had offered him refuge in Xu Province, and seized control of the province from his host. Although he had agreed to an alliance with Yuan Shu earlier, he severed ties with him after Yuan declared himself emperor – treason against Emperor Xian of Han – and joined Cao and others in attacking the pretender. However, in 198, he sided with Yuan Shu again and came under attack by the combined forces of Cao and Liu, resulting in his defeat at the Battle of Xiapi in 199. He was captured and executed by strangulation on Cao's order.
