|Literal meaning||"honorable and auspicious"|
Chongzhen (5 February 1628 – 25 April 1644) was the era name of the Chongzhen Emperor, the last emperor of the Ming dynasty of China, and was also the Ming dynasty's final era name. It was used for 17 years.
In 1622 (Tianqi 2), Zhu Youjian was created the Prince of Xin (信王) by his elder brother, the Tianqi Emperor. In 1627 (Tianqi 7), his elder brother, the Tianqi Emperor, died, and Zhu Youjian ascended to the throne. The era names proposed by the cabinet are "Qiansheng" (乾聖), "Xingfu" (興福), "Xianjia" (咸嘉), and "Chongzhen" (崇貞), for Zhu Youjian circle to choose from. Zhu Youjian circled "Chongzhen" (崇貞) and changed "貞" to "禎". According to one statement, the four era names presented are "Yongchang" (永昌), "Shaoqing" (紹慶), "Xianning" (咸寧) and "Chongzhen" (崇貞). The following year (1628), the era was changed to Chongzhen.
In February 1644 (Chongzhen 17, 2nd month), Li Zicheng established the Shun dynasty in Xi'an, Shaanxi, with the era name "Yongchang" (永昌). On 25 April 1644 (19th day of the 3rd month), the Shun army captured Beijing, the capital of the Ming dynasty. The Chongzhen Emperor hanged himself in Meishan, Beijing (present-day Jingshan, Beijing), and the Ming dynasty fell. After hearing the news, Zhu Yousong, Prince of Fu, ascended the throne in Nanjing, the temporary capital, on 19 June of the same year (15th day of the 5th month), as the Hongguang Emperor, and established the Southern Ming regime. He continued to use the Chongzhen era name until the end of New Year's Eve of 1644 (Chongzhen 17), and the following year, the era was changed to Hongguang.
After the fall of the Ming dynasty, the Joseon scholars, out of anti-Qing sentiment and Little China ideology, still used the Chongzhen era name in their country. This is called the "Chongzhen Era" (崇禎紀元).
