I'd be okay with introducing the Athenian concept of ostraophoria- Ostracism was a political process used in 5th-century BCE Athens whereby those individuals considered too powerful or dangerous to the city were exiled for 10 years by popular vote. Some of the greatest names in Greek history fell victim to the process, although, as the votes were often not personal but based on policies, many were able to resume politics after they had served the statuary 10 years away from their home city. Nevertheless, ostracism was the supreme example of the power of the ordinary people, the demos, to combat abuses of power in the Athenian democracy.
