Zionism - like all forms of modern Judaism - considers itself an obvious consummation of thousands of years of Judaism and of Jewish longing for the Land of Israel. Yet, like all forms of Judaism today, it is quintessentially modern. It is in fact a secular revolution that that draws selectively on Jewish tradition - choosing some texts over others, some traditions over others - to makes its case for authenticity. This lecture will explain the emergence of the Zionist movement and trace how it fits into the mosaic of modern Judaisms in the 20th and 21st centuries.
