Overview of the whether “Britain created Israel”
It is incorrect to say that Britain created Israel, as they spent years actively working to prevent the establishment of a Jewish state. What confuses people is that Britain changed tack. In Zionism’s early years Britain looked favourably upon the creation of a Jewish National Home, but this stance changed once they became the controlling power in British Mandatory Palestine.
Britain’s positive position reached its peak in 1917 when the British government issued a letter to Baron Walter Rothschild. The letter, now known as the “Balfour Declaration”, instructed Baron Rothschild to inform the Zionist Federation that the British Government “view[ed] with favour the establishment in Palestine of a national home for the Jewish people”. At the time of the declaration the number of Jews living in Israel was between 80,000 and 90,000. What most people may not know is that these Jews had already established a de facto Jewish National Home.
The Balfour Declaration did not establish a Jewish state, it was an endorsement by the British government of a Jewish protectorate. An endorsement they abandoned upon taking control of the land. They then began doing everything they could to prevent the establishment of a Jewish State.
