Political Zionism, developed by Theodor Herzl, stemmed from the Dryfus trial. He realized that the Jews needed a safe haven in order to escape anti-semitism. Labor Zionism, by AD Gordon states that the only way to break the classic, weak, Jewish identity is to work all the time until it hurts. Cultural Zionism, advocated by Ahad Haam, focuses on unity and quality of a Jewish homeland. Religious Zionism, represented by Rav Kook, values being a light unto other nations.
