After Dong Zhuo's death, some considered making Liu Yu emperor because he was part of the imperial family, though this began to wane as the coalition members turned their attention to enlarging their own armies rather than trying to restore the Han dynasty as things became more unstable. This resulted in the central government collapsing and Emperor Xian being captured by various warlords as they captured Chang'an. Lü Bu was attacked by Don Zhuo's officers and his co-conspirator and his entire family was executed but Lü Bu managed to escape to join with Yuan Shao who was in Ji Province and pushed north of the Yellow River, taking control from the previous Governor.
Yuan Shu, Cao Cao, Lü Bu, and Tao Qian, the Governor of Xu Province, fought over control of the land between the Yellow and Huai Rivers. Cao Cao was able to end the Yellow Turban uprising and then drove Yuan Shu south of Huai, devastated Tao Qian because Tao Qian's subordinate had killed his father, and had Liu Bei, Tao Qian's general, surrender to him. In 196, he gained control over Emperor Xian, acting as a loyal minister and used this position to give him the 'formal legal authority to control the other warlords and force them to comply in order to restore the Han dynasty. He executed Lü Bu and ended up controlling southern China by 198.
Yuan Shu established a capital at Shouchun, modern day Anhui, after he was driven south by Cao Cao, though he attempted to push back north to regain the territory he'd lost. He declared himself Emperor in 197, though this drew the ire of many warlords and caused many of his subordinates to abandon him. He died in 199.
In 200, Cao Cao was fighting Yuan Shao's forces around Guandu while a detachment of Cao Cao's army forced Liu Bei to flee to Jing Province, where he sought refuge and was able to maintain those followers who went with him and gained more followers through Liu Biao, the Governor of Jiang Province. In 2088, when Liu Biao died, he opposed the political machinations that put Liu Biao's youngest child, Liu Cong, in the position of governor. Liu Cong surrendered to Cao Cao, allowing Cao Cao to take control of the province. Liu Biao's oldest son, Liu Qi, joined with Liu Bei and they established a line of defense at the Yangtze River to fight against Cao Cao's take over of the province. They would eventually be forced to retreat, seeking support from Sun Quan who had power over the lower Yangtze River, though they were able to keep control over most of Jing's fleet of ships. Cao Cao took control over the port at Jiangling and worked his way eastward, demanding that Sun Quan surrender to him. At Red Cliffs, or Chibi, Cao Cao was defeated and forced to retreat back north by the alliance.
Zhou Yu, who served under Sun Quan, gained control over Jiangling in 209 and Liu Bei captured the Xiang River basin, taking control over the Southern part of Jing Province, though Sun Quan had to cede his control over Jiangling to Liu Bei after Zhou Yu's death in 210 because he lacked the ability to establish authority. In 211, Liu Bei received an invitation from Liu Zhang to aid Yi Province against a northern threat. There were factions in Liu Zhang's court that wanted Liu Bei to be in control of Yi Province, which caused conflict between the two leaders so that within a year, Liu Bei turned against Liu Zhang . By 214, Liu Zhang surrendered Yi Province to Liu Bei.
During this time, in 211, Cao Cao defeated the warlords who had control over the Wei valley, allowing him to capture Chang'an. In 215, he captured Hanzhong, which threatened Liu Bei's territory to the south. Sun Quan was fighting Cao Cao's forces over the middle Yangtze, but they were at a stalemate. Sun Quan resented Liu Bei, however, since he was the weaker ally and had so much more territory and he demanded to have more of the Xiang River basin. They were able to reach an understanding later in the year where the Xiang River would be the border between them.
In 219, Liu Bei was able to seize Hanzhong from Cao Cao, which gave Liu Bei territories security against invasion from the north. He declared himself King of Hanzhong. Sun Quan was also trying to take territory, specifically Hefei, from Cao Cao but he failed in his efforts. When Lu Su, Sun Quan's chief commander, died in 217, he switched his alliances from Liu Bei. In 219, Lü Meng, Lu Su's replacement, captured Jiangling in a surprise attack allowing Cao Cao to regain control over the Han valley and Sun Quan to gain the territory east of the Yangtze Gorges.
