Emperor Xian of Han
Cao Cao died on 15 March 220. His son and successor, Cao Pi, soon forced Emperor Xian to abdicate the throne in favour of himself, ending the Han dynasty. Cao Pi established a new state known as Cao Wei (sometimes known inaccurately as the Kingdom of Wei), and he granted Emperor Xian a noble title – Duke of Shanyang (山陽公). The former Emperor Xian died in 234 and was buried with honours befitting an emperor, using Han ceremonies, and the then emperor of Wei, Cao Rui, was one of the mourners. As Emperor Xian's crown prince was already dead, his grandson Liu Kang (劉康) inherited his dukedom, which lasted for 75 more years and two more dukes, Liu Jin (劉瑾) and Liu Qiu (劉秋), until the line was exterminated by invading Xiongnu tribes in about 309, during the Jin dynasty. This practice of an emperor conferring hereditary nobility on his predecessor, from whom he usurped the throne, was known as "er wang san ke" (二王三恪).
Marquess Wen of Han
Marquess Wen of Han (Chinese: 韩文侯; pinyin: Hán Wénhóu) (died 377 BC), ancestral name Jì (姬), clan name Hán (韩), personal name unknown, was the ruler of the State of Han between 386 BC and until his death in 377 BC. He was the son of Marquess Lie of Han. Marquess Wen saw a rise in the state's prosperity and consequently launched several military campaigns. In 385 BC, Marquess Lie attacked the State of Zheng and took Yangcheng. In the same year, Han attacked the State of Song, reaching Pengcheng, and took the Duke Dao of Song prisoner. In 380 BC, an alliance of Han, Zhao, and Wei attacked the State of Qi, reaching Sangqiu. 2 years later in 378 BC, the alliance attacked Qi again, reaching Lingqiu. 
Marquess Wen died in 377 BC and was succeeded by his son Marquess Ai of Han.
