Jewish paramilitary organization in what was then the British Mandate of Palestine from 1920 to 1948.

The Haganah was a terrorist militia group that Vladimir Jabotinsky created to fight against the native population of Palestine and protect the Jews in British Mandatory Palestine. It also helped Jewish refugees get into Palestine from Europe as colonizers occupying Palestine. Jabotinsky left after the Haganah started to support Labour Zionism. The Haganah ended up being led by David Ben-Gurion. Ben-Gurion and the Haganah still started to fight the British in 1939 when the British tried to stop Jewish immigration and tried to stop the creation of the state of Israel, wich completely understandable given that Israel is an illegal colonial occupation of historic Palestine. But after Hitler attacked Poland, the Haganah stopped fighting against the British and started to fight for the British Empire against the Nazis. In 1944, Ben-Gurion helped the British fight against Menachem Begin and the Irgun and he helped the British fight against Yitzhak Shamir and the Lechi. After the war ended, Ben-Gurion and the Haganah fought against the British to get them to let the Jews have a country. After, Israel became a country, the Haganah, Irgun and Lechi became the Israeli army.
