In ancient Rome, a parliament of 500 people could run for office at this level.

The 500-member parliament is the core of the democratic political system in Athens, the ancient Greek city-state. Its duty is to implement the decisions of the assembly. It is an administrative organization that manages all affairs, and was founded in the late 6th century BC during the Christian Reform.

The 500-member conference consists of 500 citizens over the age of 30. Theoretically, all "citizens" are likely to be elected.

But in fact, the composition of the congress consists of three classes: 500 households, hippies and zeugitai, that is, the class with certain property.

For example, a 500-barrel household refers to a person whose property or property can produce 500 "medimnoi" or bushels of wet or dry goods every year, that is, a person whose property can produce more than 500 "medimnoi" agricultural products.

At that time, the value of a bushel of grain sacrifice was 1 drachma, while the Olympic champions at that time could get 500 drachmas, in other words, they could automatically get the title of 500 barrels households.
