Israel didn't exist in 1920. That area was called Palestine and was ruled by the British.
United Kingdom. The British carved out the Mandate of Palestine in 1919. It took its current shape (dropping Trans-Jordan) in 1922.
After World War I, the League of Nations granted Britain a mandate over Palestine. The British Mandate for Palestine was established in 1920 and lasted until 1948. This mandate was intended to facilitate the establishment of a Jewish national home while also ensuring the rights of the existing Arab population.
The modern State of Israel came into existence in 1948. In 1940, the area where Israel predominantly sits (excluding the Golan Heights) was called the British Mandate of Palestine. The Mandate of Palestine was not a country, but a colony of the British Empire. What made a mandate different from a colony was that the British had an obligation to help the people living in the territory to form their own government and facilitate independence. In the specific case of the Mandate of Palestine, they were required to do this for the Jews and the Arabs together.
It was known that eh League of Nations (currently the United Nations) gave Britain the task of controlling Palestine therefore creating the British Mandate for Palestine. The Mandate lasted from 1920-1948.
Great Britain administered Palestine on behalf of the League of Nations between 1920 and 1948, a period referred to as the "British Mandate." Two states were established within the boundaries of the Mandate territory, Palestine and Transjordan (Jordan).

Before the Israeli declaration of independence in 1948, the land was the British Mandate of Palestine. The United Nations had decided to split Palestine into four zones, with two zones going to the Jews and two zones to the Palestinians, providing approximately half of the former Palestine to each. The Palestinian share was gradually reduced, until the UN defined a "Green Line", providing the Palestinians somewhat more than the 1967 borders.
After World War I, the land of Palestine came under British control as a result of the League of Nations mandate system. The British Mandate for Palestine was formally established in 1920, giving the United Kingdom administrative authority over the region. This period was marked by increasing tensions between Jewish and Arab populations, as both communities sought national recognition and rights in the territory.
Palestine Railways was created in 1920.
Iraq, Syria, Lebanon, Transjordan (now Jordan), and Palestine were established as distinct political entities during the aftermath of World War I, particularly with the Sykes-Picot Agreement in 1916 and the subsequent League of Nations mandates in the early 1920s. The modern borders and political structures of these countries largely took shape between 1920 and 1922. Iraq was formally recognized as a kingdom in 1921, Syria and Lebanon were established as French mandates in 1920, and Transjordan was separated from the Palestinian mandate in 1923. Palestine was designated as a British mandate in 1920, with its status evolving over the following decades.
In 1920 the only dictatorship among those countries was Russia.
