David Ben Gurion was a man of the Second Aliyah, the head of the leadership of the “nascent state”, the driving force behind the establishment of the State of Israel, and the declarer of the independence of the State of Israel. After its birth, he led the State for 15 years, until 1963. He served as the first Prime Minister and Minister of Defense of Israel and he was a leader of the labor movement. His understanding of the importance of a national army led him to disband the militias on the eve of the War of Independence and to establish the Israel Defense Forces (IDF).
In 1906, when he was only 20 years old, he came to Israel as part of the Second Aliyah. Years later, he said that was the greatest day of his life. The second greatest day was during the Six Day War when the Temple Mount (Har Haba’it) was liberated.
In his first years in the Land of Israel, he worked as a farmer in Petach Tikva, Segera, where he was also a guard, Menahemia, Zichron Ya’akov, Kfar Saba and the Kinneret Farm
He joined the socialist-Zionist party, “Poalei Zion” and was among the leaders of the right-wing faction of the party, He was one of the five members of the Central Committee. In 1907, at the second session of the committee of “Poalei Zion”, which was held in Jaffa, he succeeded in adding the clause, “The party aspires to an independent state for the Jewish people in this land.” He also managed to get elected (together with Israel Shochat) to the two-member committee which would reorganize the party.
In 1917, following the Balfour Declaration and the conquest of the land by the British, he was among those who encouraged people to volunteer for the “Hebrew Brigades”, and he himself was one of the first to volunteer. In 1918, he reached Egypt as a member of the 39th Brigade of the King’s marksmen in the British army and from there, he continued to the Land of Israel. In 1919, together with Berl Katznelson, he founded the party, Ahdut HaAvoda , which merged “Poalei Zion” with unaffiliated groups.
At the beginning of the 1920s, Ben Gurion became one of the most outstanding leaders of the Yishuv. In 1920, he was one of the founders of the HaHistadrut HaKlalit and served as its Secretary General for 15 years. He saw in the Histadrut not only s professional organization which would protect the workers in the Land of Israel, but also a social and economic tool that would establish an framework for self-employed workers. He also saw it as a political institution that would lead the Jewish settlement and would lay the foundations for the future state.
