The forms of government changed over time dramatically. Thethree governments were monarchy, aristocracy, and oligarchy. Theidea of a monarchy started to shrink in the 750 BC. This happenedbecause the people that were able to help the citizens, were thepeople that could actually afford to buy things. These people werepart of the noble landowners. This then involved the governmentinto an aristocracy, ruled by the hereditary landholding elite.Then, as trade increased, wealthy merchants, farmers, and artisansbegan to take over and turn the government into and Oligarchy.Oligarchy is when the power is in the small wealthy elite. The mainreason different forms of government introduced themselves isbecause the demand for an influential leader. For example, in atime of an economic boom, citizens would want a government thatwould be able to fill their needs and desires, not one that isunfamiliar with trade.
