Ma Teng
Ma Teng rose to major under Inspector Geng Bi until Geng Bi was killed by mutineers in 187. Ma Teng then joined the mutineers, styling himself a general under the command of Wang Guo. After Wang Guo was defeated in 189, Ma Teng set himself up as an independent ruler in Longxi Commandery. When Dong Zhuo retreated to Chang'an, he persuaded Ma Teng and Han Sui to assist him against the other warlords. Ma Teng continued his allegiance to the Chang'an regime for a time even after Dong Zhuo's death and usurpation by Li Jue. In 194, he betrayed Li Jue and attacked Chang'an with the aid of Han Sui and supporters in Luoyang. Ma Teng and Han Sui were defeated at Changping Slope northwest of Chang'an and he retreated to Liang Province. Around 197 Ma Teng began to quarrel with Han Sui and their forces engaged in battle with Ma Teng losing the exchange. His son Ma Chao was wounded in battle by Yan Xing while his wife and other sons were also lost, forcing him to retreat to Youfufeng Commandery. He threw in his lot with Cao Cao in 202, sending Ma Chao to fight Yuan Shao's officer Guo Yuan in Hedong Commandery, and in 205 he himself campaigned against Sun Quan's officer Zhang Cheng. In 208 Ma Teng was enfeoffed but kept hostage in Ye while his son Ma Chao succeeded him in Liang Province. In 211 Ma Chao and Han Sui became hostile to Cao Cao. Ma Teng was killed the next year.
