Lê Văn Duyệt was a Vietnamese general who helped Nguyễn Ánh—the future Emperor Gia Long—put down the Tây Sơn wars, unify Vietnam and establish the Nguyễn dynasty. After the Nguyễn came to power in 1802, Duyệt became a high-ranking mandarin, serving under the first two Nguyễn emperors Gia Long and Minh Mạng.

Nguyễn Phúc Cảnh (1780–1801), also known as Prince Cảnh, was the eldest son of the Vietnamese Prince Nguyễn Phúc Ánh, the future Emperor Gia Long. At the age of seven, he famously visited France with the French Catholic Father Pigneau de Béhaine to sign an alliance between France and Vietnam. Although Prince Cảnh was the legitimate heir to the throne, he died before his father, and none of his descendants ascended the throne after his half-brother Nguyễn Phúc Đảm was chosen by Gia Long.
While in France, Nguyễn Phúc Cảnh resided in the 1732 building of the Paris Foreign Missions Society.
