This study aims to conduct both a historical and a conceptual analysis of Walter Benjamin s perceptions on law and politics, locating them in the historical context of the Weimar Republic (1918/9 - 1933 ). Through this articulated analysis, the purpose is to expose the main features of Benjamin s debates, analyzing his writings that face the discussions on law and politics, the struggles around the concept of state of exception, and its relation with author s philosophy of history.It will also be important to unfold such reflections, indicating the questions posed, the inflections incurred in relation to his previous thought and the incorporation of new issues. Benjamin will therefore be analyzed with reference to his own time, indicating as well his specificities as author and the answers given to this time that particularizes him.The central hypothesis of this study is that for a better understanding of Benjamin s political and legal writings is fundamental to analyse them together with the context from which they emerged, recognizing that the problems raised by the author go beyond him and, from that particular context, he lifted questions concerning particular tendencies of modernity which still are issues of our time.
