Palestine
Palestine has never been a colony of Israel. Israel took control of the West Bank and the Gaza Strip in 1967 after conquering these territories from Jordan and Egypt respectively, where they were annexed territories under military authority.
Israel was a part of the British Mandate for Palestine, a quasi-colony under British authority.
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.
Israel was formed out the British Mandate for Palestine, which was effectively a colony run by the British Empire. Before that it was part of several Ottoman governates. There was no independent state in the Palestine region since the Crusader States in the 1200s.
Israel is also known as the State of Israel or the Land of Israel. Palestine is also referred to as the State of Palestine or the Palestinian Territories.
