[영문]This article offers a theoretical and methodological system for a sociological analysis of the restless nature of historical events. This system, political semiosis, is able to identify and assess the performative speech acts, the demonstrative orientational specifications, and the mimetic representations required to advance historical transformations. The features of political semiosis structure the flow of historical events by managing the specific media and generic forms that are the vehicles through which events take shape. Political semiosis provides a method for analyzing both the circulation and the materialization of events. The exemplary case of September 11 illuminates this approach's capabilities.
