Hunter and Gatherers
The hunter gather system was an ancient system used by humans around 1.8 million years ago. Tribes and clans of families usually had a chief to make decisions based on advice given by family members. This takes a democratic pattern in itself. The hunter gatherer system lasted until the end of the Medolithic period 10,000 years ago and was replaced with the Neolithic Revolution.
Some tribes made towns in fertile areas by different clans and Kings of the clans were known to be greedy and sharge high taxes for protection against other leaders fighting for land. Clergies and nobles challenged the Kings which lead to dictatorship.
