Zhengde (Chinese: 正德; pinyin: Zhèngdé; Wade–Giles: Cheng-te; lit. 'rectification of virtue'; 24 January 1506 – 27 January 1522) was the era name (nianhao) of the Zhengde Emperor, the 11th emperor of the Ming dynasty, lasting for 16 years.
On 27 May 1521 (Zhengde 16, 22nd day of the 4th month), the Jiajing Emperor ascended to the throne and continued to use the Zhengde era name. The following year, the era was changed to Jiajing.[1][2]
