"Transjordanian Palestine" Does Not Exist—Clarifying Transjordan/Jordan

There is no region called "Transjordanian Palestine." The term conflates two distinct historical-geographic concepts:

Transjordan / East Bank

• Refers to the territory east of the Jordan River.
• Became the Emirate of Transjordan (1921) under British mandate.
• Independent as the Hashemite Kingdom of Jordan (1946).

Palestine / West Bank

• Refers to territory west of the Jordan River (including Jerusalem).
• Under British Mandate (1920–1948); later divided (Israel, West Bank, Gaza).

Population of Jordan (East Bank)

• Majority: Jordanian Arabs (many of Palestinian origin, displaced 1948/1967).
• Minorities: Circassians, Chechens, Armenians, Bedouin tribes.
• Refugees: ~2.3M registered Palestine refugees (UNRWA) in Jordan—many citizens.

Jordan and the West Bank are separate political entities; the Jordan River is the internationally recognized boundary.
