Haganah was the main Zionist paramilitary organization that operated for the Yishuv in the British Mandate for Palestine. It was founded in 1920 to defend the Yishuv's presence in the region, and was formally disbanded in 1948, when it became the core force integrated into the Israel Defense Forces shortly after the Israeli Declaration of Independence.
