When Cao Pi, emperor of the state of Cao Wei, appointed Sun Quan the King of Wu in 221, he enfeoffed Sun Deng as the Marquis of Wanhu (万户侯). However, Sun Quan refused the title for his son as he was only 12 years old. One year later Sun Quan designated Sun Deng as the Crown Prince. When Cao Pi demanded that Sun Quan send Sun Deng to the Wei capital Luoyang as a hostage, to guarantee his loyalty, Sun Quan refused and declared independence.
Life and deathEdit
It is recorded that Sun Deng was both wise and virtuous, having all the makings of a great man. Sun Quan ordered Zhuge Ke (諸葛恪), Gu Tan (顧譚), Zhang Xiu (張休), Chen Biao (陳表) and others to serve as the Crown Prince's attendants and personal staff. Sun Deng treated his staff kindly. For instance he allowed others to ride with him and sleep close to him. The Crown Prince's palace was considered to have the largest number of outstanding people in China.
Sun Deng showed his filial piety to both his father and adoptive mother, even through Lady Xu was divorced from Sun Quan in 212. Aged 20 Sun Deng studied the Book of Han under his father's order. When Sun Quan declared himself emperor in 229 and later moved his capital from Wuchang (武昌; in present-day Ezhou, Hubei) to Jianye, Sun Deng and his younger brothers were left in Wuchang. Sun Deng was in charge of the western parts of Eastern Wu with the help of Lu Xun and Shi Yi until his brother Sun Lü died in 232. He then travelled to Jianye to accompany his father and lived there since then.
In 234, Sun Quan personally led a major attack against Wei's border city Hefei. He let Sun Deng to stay in rear area. At that time Sun Deng made some laws to prevent crime，which achieved result successfully. However, Sun Deng never succeeded his father, dying from illness aged 32. Before he died he wrote a letter to inspire his father and recommend talented individuals. Sun Deng was buried in Jurong, Jiangsu initially, then moved to the Jiang Mausoleum (蔣陵) at the Purple Mountain in Jiangsu. He was posthumously honoured as "Crown Prince Xuan".
In 225, on the arrangement of Sun Quan, Sun Deng married Zhou Yu's daughter. She thus carried the title of Crown Princess. Sun Deng also had another wife, Bing Xuan's (邴玄) daughter. Sun Deng had three children: Sun Fan, Sun Ying (孫英), and Sun Xi. The mother's identity of each is unknown. Both Sun Fan and Sun Xi died at their early age. Thus Sun Ying was enfeoffed as the Marquis of Wu when he grew up. However, Sun Ying was eventually executed because he was accused of attempting to assassinate Sun Jun, the regent who served under the second Wu emperor Sun Liang.
- Sun Quan's biography in the Sanguozhi recorded that Sun Deng died in the 5th month of the 4th year of the Chiwu era of Sun Quan's reign. This month corresponds to 28 May to 25 June 241 in the Gregorian calendar.
