Copy and Paste from wiki: Ostracism (Greek: ὀστρακισμός, ostrakismos) was a procedure under the Athenian democracy in which any citizen could be expelled from the city-state of Athens for ten years. While some instances clearly expressed popular anger at the citizen, ostracism was often used preemptively. It was used as a way of neutralizing someone thought to be a threat to the state or potential tyrant. It has been called an "honourable exile" by scholar P. J. Rhodes.[1] The word "ostracism" continues to be used for various cases of social shunning. Each year the Athenians were asked in the assembly whether they wished to hold an ostracism. The question was put in the sixth of the ten months used for state business under the democracy (January or February in the modern Gregorian Calendar). If they voted "yes", then an ostracism would be held two months later. In a section of the agora set off and suitably barriered,[2] citizens gave the name of those they wished to be ostracised to a scribe, as many of them were illiterate, and they then scratched the name on pottery shards, and deposited them in urns. The presiding officials counted the ostraka submitted and sorted the names into separate piles. The person whose pile contained the most ostraka would be banished, provided that an additional criterion of a quorum was met, about which there are two principal sources: According to Plutarch,[3] the ostracism was considered valid if the total number of votes cast was at least 6000. According to a fragment of Philochorus,[4] the "winner" of the ostracism must have obtained at least 6000 votes.
