The specialist in Roman history of Antiquity, Nikita Tsybikov, proposes to trace the political history of Rome from the first symptoms of the crisis of the republican model in the second half of the 2nd century BC to the decline of the rule of the first dynasty of emperors from the Julio-Claudian family in the second half of the 1st century AD.

The history of the Weimar Republic is inextricably linked with the history of political parties. Like the republic itself, these parties did not appear out of nowhere and did not disappear into nothingness.
