Ostracism

Ostracism, or *ostrakismos*, was a unique democratic procedure used in the ancient Greek city-state of Athens. It allowed the citizens to vote to expel a person from the city for ten years. This was not a criminal trial where someone was punished for a specific crime. Instead, it was a preventive measure used to protect the state. Athenians used it to neutralize people they thought were a threat to democracy. They often targeted potential tyrants, which are leaders who might try to take total power.

The entire process relied on a specific mechanism involving two distinct stages. Every year, during the sixth month of the Athenian state business calendar, the assembly was asked if they wanted to hold an ostracism. If a majority of citizens voted "yes," the actual voting would take place two months later. This two-month gap was important because it allowed for public discussion or political campaigning. During the second stage, a specific area of the agora, or marketplace, was set aside. This area was called a *perischoinisma*. It was either roped off or blocked with wooden planks to create a controlled voting space.

To cast a vote, citizens used small pieces of broken pottery called *ostraka*. Using pottery was a practical choice because it was abundant and free. It was much cheaper than papyrus, which was an expensive writing surface imported from Egypt. Because many citizens were illiterate, they would tell a scribe the name of the person they wanted to expel. The scribe would then scratch that name onto the shard. These *ostraka* were piled up face down to ensure the voting remained anonymous.

Several officials and strict rules oversaw the procedure to ensure fairness. Nine Archontes and a council of five hundred supervised the entire process. The Archontes were responsible for counting the *ostraka* and sorting the names into separate piles. For an ostracism to be valid, a quorum, or a minimum number of votes, had to be met. According to the historian Plutarch, this quorum was 6,000 votes. Once the count was finished, the person with the most votes was banished. This person had ten days to leave the city, and returning before the ten years ended could result in death.

Despite the severity of being sent away, the penalties were actually quite regulated. Unlike a court trial, the person being ostracized did not lose their property or their social status. They were not stripped of their rights, and they could return after a decade without any stigma or shame. This made ostracism a pragmatic political tool rather than a purely punitive one. It was designed to reduce political tension by temporarily removing a divisive leader. In some cases, the assembly even recalled people early during emergencies. For example, the leader Cimon was recalled in 461 BC during a crisis.

History shows that ostracism was most active during the fifth century BC. It is attributed to the reformer Cleisthenes, who likely established the practice around 506 BC. The first person to be expelled was not sent away until 487 BC. Over the next sixty years, at least twelve or more individuals were ostracized. Famous figures included Themistocles, who was exiled around 471 BC, and Aristides "the Just." Archaeologists have excavated about 12,000 political *ostraka* in Athens, which helps historians understand how often this happened.

Ostracism differed significantly from other Athenian legal systems. In a standard trial, a prosecutor must bring a specific charge, and the accused can offer a defense. In ostracism, there was no charge and no defense allowed. It was a "diffuse" exercise of power, meaning the responsibility for the decision lay with the entire community rather than one individual. This helped prevent personal vendettas from dominating the process. While it was not used in the fourth century BC, the question of whether to hold an ostracism was still asked by the assembly every year.
