This thesis discusses Yehuda Bauer's nuanced approach to Jewish resistance in Eastern Europe during World War Two. It applies his reinterpretation of the Hebrew term 'amidah', and the idea of 'sanctification of life' as resistance, to the Nazi-occupied ghettos of Eastern Europe. It takes specific focus upon the largest two ghettos, that of Warsaw and Lodz. In addition to the application of Bauer's concept of resistance to these ghettos, a comparative analysis is made. This study considers what forms of resistance were displayed in each ghetto and why this was the case. By so doing, it offers a new and more nuanced approach to Jewish resistance within the ghettos.
