In recent years, various philosophical, political, social and economic schools have had a clear and profound influence on the geographic debate and have created new ideas. Radicalism is also one of these schools that was able to provide a deconstructive approach to solve as much as possible the problems that space had to deal with, and to eliminate many of the established trends in geography. It is within this approach that radical geographers consider geographic space to be a historical-socio-political category that has been inscribed in nature. But what is most apparent in this school is the exploitation of Marxist and socialist ideologies.
This article seeks to answer the question whether the legitimacy of radicalism in geography is due to its opposition to the views and frameworks that shape the geographic space for the benefit of the owners of power and capital or merely a paradigm that challenges the space perspective. To reach this goal, the author has tried to collect and analyze the issues using the documentary research method and referring to library resources. By studying the foundations of radicalism and its different perspectives, it clarifies the extent to which this school has been influenced by other ideologies as well as its impact on geographic studies, and discusses the various spaces that the advocates of this school have introduced in geography.
