Need some help with the various types of governments.Thanks!?

Question

If anyone knows: what laws are implemented, how "ruler" is chosen, when was first developed and used, which countries use it today and how it got there meanings and nationality of origin.Thanks!
Aristocracy
Autocracy
Despotism (All I know is ancient Egypt is an example of it.)
Meritocracy
Oligarchy
Plutocracy
Theocracy (Know that the ruler is "god", thats about it)
Tyranny (Know what it is, and some instances, just not who developed it.)

Once again, thanks for taking the time to look at my question!

Answer 1

Okay, alot of these kinda cross over one another...
Aristocracy and plutocracy kinda mean the same thing; rule by the wealthy. Aristocrats are wealthy people who pass down hereditary titles and have special rights and priveledges based on their societal status.
Oligarchy means rule by a small group (typically the aristocrats)
Theocracy means rule by the religous leaders or church. An example would be the city-state of the Vatican, where the Catholic church IS the government.
A Meritocracy is a theoretical government where leaders are selected on 'Merit' - none exist for the simple reason that 'who decides merit?'
Autocracy is rule (typically) by a single leader with dictatorial power, also called Dictatorships, similar to Tyrrany, but tyrrany implies a cruel and overbearing Autocrat.
Tyrrany can also be by a group, not just a single person.
Despotism is similar to a dictatorship and tyrrany, but implies more of an organised crime form of control, also called 'Thugocracy' (rule by thugs). An example would be Iraq under Saddam.
There are tons of other types and definitions of governments, hope this helped.

Answer 2

At first there were family heads who ruled extended families (Abraham, Isaac, and Jacob were examples). Then there are associations of heads of families as an association (the elders of the families of the sons of Jacob, trying to behave together as the sons of Jacob did, would be an example). As the families grew, they came to be clans or tribes. The elders usually had special rank or sometimes replaced by people with special abilities, acclaim, or accomplishment (the Biblical "mighty men" of David were such a meritocracy). People often chose a special person from among them, a special leader usually after some particular accomplishment, and that became their king. Kingship usually passed to the children (usually the eldest son), whether good or bad (monarchy, as in mono--one--arch--over). Then some places, commonly in the Greek world (which also included much of what we now call Turkey), people simply had enough with stupid kids becoming stupid kings, and the people chose a leader from among themselves, and this was a democracy. Sometimes the leader became strong enough to flaunt the will of the people, so he made himself "leader for life" or some such title (despotism). Sometimes the leader is chosen because of the prestige that comes with wealth. Rome, under the republic, was ruled by the Senate which were appointed from rich and powerful old families. This is a plutocracy. A theocracy, meanwhile could be any of these when the religion trumps the wishes of the rulers. In most of human experience at ancient times kings were often kings at the blessing of the priests of various deities. Even Rome was a theocracy at times, as was Egypt, as definitely was Israel, as were Babylonians, Persians, etc.

Answer 3

A good example of Tyrannical rule would be early China their early dynasties are rampant with it.
