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 Jing of Han
Marquess Jing of Han (Chinese: 韩景侯; pinyin: Hán Jǐnghóu) (died 400 BC), ancestral name Jì (姬), clan name Hán (韩), personal name Qían (虔), was the ruler of the State of Han between 408 BC until his death in 400 BC. Marquess Jing was the son of Wuzi of Han. It was during his rule that the State of Han became a recognized state. In the first year of his reign, he attacked the State of Zheng and took over Yongqiu in today's Qi County, Henan. The next year, his army lost to Zheng at Fushu in today's Dengfeng, Henan. In 403 BC, Marquess Jing, along with Marquess Wen of Wei and Marquess Lie of Zhao partitioned the powerful Jin state into the Han, Wei, and Zhao states marking the beginning of the Warring States Period and Han as an independent polity. King Weilie of Zhou was forced to elevate Jing's title from viscount to marquess. Marquess Jing then moved the capital of Han from Pingyang to Yangzhai. In 400 BC, the capital Yangzhai was subject to a siege by the Zheng army. Marquess Jing died later that year and was succeeded by his son Marquess Lie of Han.
