The Jiajing Emperor (September 16, 1507–January 23, 1567) was the 11th emperor of China (Ming dynasty) between 1521-1567.
The throne became vacant with the sudden death of Emperor Zhengde in 1521 and the 14 year old Jiajing was eventually chosen to become emperor and relocated from his father's fief to Beijing.
Particularly during his later years, Jiajing was known for spending a great deal of time on alchemy in hopes of finding medicines to prolong his life.
