I thought it would be interesting to create a timeline to show the evolution of three great political systems: Greek, Roman, and British.
Between them we cover the two great civilizations of antiquity and their political systems – Democracy and Republic. Britain is, perhaps, the father of the great modern political systems.
The Greeks were at it early as they were influenced by the empires of the Eastern Mediterranean: Egypt, Persia, Crete, and Mesopotamia. They had a mature Polis when Rome was just starting its Republic. Neither Greece nor Britain could move forward to the Middles Ages until Rome collapsed.
