In Ancient Greece the Athenians had a procedure known as "ostracism" in which all citizens could write a person's name on a shard of broken pottery (called ostraka) and place it in a large container in a public place. If an individual's name was written a sufficient number of times, he was "ostracized"—banished from the city for ten years. This was normally practiced against individuals who had behaved in some way that offended the community.
