Law of the Twelve Tables
Rome's laws that were written on 12 bronze tablets! Written down to protect people's rights so that everyone knew what the laws were.
"The best known ancient code is the Babylonian Code of Hammurabi. The Romans began keeping legal records, such as the Law of the Twelve Tables (451–450 bc), but there was no major codification of Roman law until the Code of Justinian (ad 529–565), which was compiled long after the dissolution of the Western Empire."
Oligarchy is the political system that is run by a group of noble families or wealthy members of a society. The term Oligarchy was first used by the great Aristotle for describing the powers that were held by a very small and highly privileged group. These people often misused their powers and treated the people under their rule very poorly and also used them to satisfy their selfish needs. It has been commonly seen that the rulers that believed in Oligarchy actually selected people on herediterary basis and not based on merit.
