Era names, or dynastic titles, like any title selected in those days, have meaning in Chinese and Vietnamese. For example, the first Emperor's era name of Gia Long, literally "House Dragon", is an union of the old names for Saigon (Gia Dinh) and Hanoi (Thang Long) to show the new unity of the country; the fourth one, Tự Đức, means "Inheritance of Virtues" and the ninth one, Đồng Khánh, means "Collective Celebration".
Following the death of Emperor Tự Đức, and according to his will, this Emperor ascended to the throne on July 19, 1883. However, he was dethroned and imprisoned three days later, after being accused of deleting one paragraph from Tự Đức's will. He had no time to announce his dynastic title (era name); hence his was named after his residential palace as Dục Đức (育德宮).
