What are the political characteristics of ancient Greece and Rome?

The politics of ancient Greece was more democratic, and after theseus and other reforms, there was more civic democracy, and the citizens' assembly had great power, so the official positions were all produced by drawing lots and pottery.

The development of Rome is like a process of centralization by consuls. Although Rome's democracy is also progressing, power is constantly concentrated in the hands of consuls. In the future, the citizens' assembly will become a virtual authority, Caesar and Octavian coming from the army will move towards dictatorship and heads of state, and the Roman Republic will also become the Roman Empire.
