Where is Transjordanian Palestine today and who lives in that part of Palestine?

Answer 1

The British Mandate of Palestine was established in 1919 and was then partitioned into what is commonly known as the British Mandate of Palestine and the British Mandate of Transjordan (because it was on the opposite side of the Jordan River). This division came into existence because the British had promised the Hashemites (an important Arab family) a Kingdom for support in World War I. As a result, Transjordan fell under the control of the Hashemite Kings. When Transjordan became independent as Jordan in 1946, the Hashemites retained control of the country and still rule it to this day.

The people of Jordan today are mixed. 40% of them consider themselves endemic Jordanians, which is to say that their ancestors lived in Transjordan before the independence because their ancestors lived in what remained in the British Mandate of Palestine until the Arab-Israeli War of 1948-9 (when presumably they fled to Jordan). It is important to note, however, that most Jordanians (endemic or Palestinian) consider themselves to be part of the same people: The Arabs of Bilaad Sham. (Bilaad Sham covers what is today Israel, Palestine, Lebanon, Syria, and Jordan, and is traditionally translated as "Greater Syria".)
