Political Zionism stressed the importance of political action and deemed the attainment of political rights in Palestine a prerequisite for the fulfillment of the Zionist enterprise. Political Zionism is linked to the name of Theodor Herzl, who considered the Jewish problem a political one that should be solved by overt action in the international arena. His aim was to obtain a charter, recognized by the world leadership, granting the Jews sovereignty in a Jewishowned territory. The Basle Program, drawn up in accordance with these principles, states that Zionism aims to establish a secure haven, under public law, for the Jewish people in the Land of Israel. Organizational and economic mechanisms (the Zionist Organization [ZO], the Jewish National Fund [Keren Kayemet L'Israel], the Jewish Colonial Trust and so on) were established to carry out this program.
