The concept of constitution was created in the West in the late 18th century to provide a response to constitutional pursuits that are as old as the history itself. We can follow the origins of constitutionalism - that which is universal in character- until the ancient Greek world. Furthermore, with its fundamental civic ethos and the distinctive constitution of the polis, this world has provided many philosophical-scientific concepts and political-legal institutions that are still in widespread use to day. As polis -as a macro public sphere- was the battleground for power struggle between the privileged rich and the poor classes, the question of justice, which initially had metaphysical associations, transformed into a constitutional issue. The resolution of this problem could be possible with such laws that are products of direct political action. Of course, a never-ending debate regarding what is just and how the political-legal sphere should be organized had never ceased to exist. To reflect upon such qualities of ancient Greek constitutionalism -whilst keeping in mind of our own distinct context- may provide us a new/renewed perspective on how to tackle our own contemporary constitutional issues such as constitutional and democratic regression.
