Neither did any of the other successor states that were carved out of the defunct Ottoman Empire so I don't see your point.There are several facts about Palestine.
The land of Palestine is inside international borders defined by post war treaties.
The Turkish citizens who normally resided on that land became Palestinian nationals.
Those Palestinians became citizens of Palestine as international legal norms specified and confirmed by the Palestine citizenship law of 1925.
This was de facto status until the Treaty of Lausanne was signed on August 6, 1924 when this status became de jure.
These natives of Palestine had certain rights:
Where are the documents showing where foreigners acquired any of that land or had the authority to create a state on that land.
For starters your source of information is wrong and its author slipped in the term Palestine to make it look legitimate. There are no treaties signed by a Palestinian giving it sovereign status and international borders.
None of the nationalities of the successor states were mentioned, however, basic principles were laid down that were universally applicable.
Palestinians were citizens of Palestine. They were never British citizens.
The mandate never offered a separate anything. Immigrants were to obtain Palestinians citizenship and join the other Palestinians in a shared sovereignty.The Jews of Palestine took up the offer in the mandate of Palestine to create a nation of their own. This gave then self determination and national sovereignty over the land destined for the Israeli nation.
The arab Palestinians declined the offer and instigated ALL OUT WAR on Israel. A war they lost and caused an amendment to the Geneva conventions that outlaws such declarations of war for ever.
It seems that you are not concerned with the rights of the Jews and Christians in Palestine to their rights of self determination without outside interference. As under an arab nation they would have no self determination at all. Making you an ISLAMONAZI JEW HATING ANTI SEMITIC POS.
Iraq, Syria, Lebanon and trans Jordan all signed treaties when they were created under the mandate
The other ottoman entities were named in the treaties, only Palestine was omitted deliberately by the parties involved.
Then why were they issued with British or French passports under the mandate
Not according to the league of nations and the mandate of Palestine, the whole idea from the start was to allocate land for each separate entity in the land of Palestine. Because the arab muslims had 3 distinct cults they were given 3 nations Syria, Iraq and Trans Jordan. The Christians were given Lebanon and the Jews were to receive the remainder of Palestine. The treaties stated that the ruling cabal would be the predominant religious entity, but that the other entities could migrate if they wanted or stay as full citizens without fear of harm. Since then the arab muslims have ethnically cleansed their nations of most Christians, muslims of a different sect and all Jews. You really should read the real facts and not the twisted biased version by some ISLAMONAZI Palestinian professor.
