What are the main governments in your world?

For Urbis, most governments on the region I am focused on are city state-based republics, although the definition of who gets to be a "citizen" varies widely. Furthermore, the people living in the "protectorates" surrounding each city-state tend to have far less of a say in politics than those living closer to the center of power.

I don't know if they can be really called "governments", more like factions in a global war.

• Human United Force: The highest power of the HUF is the HUF Council: Composed by the highest ranking generals of the nations that survived the Wipe. They rose to power as every government on Earth got killed during a genocide called The Wipe. They tried to control everyone and everything, while trying to keep the Machines at bay. Military officers were given a higher status in this society, while everyone else was essentially a slave.
• NeoTechnos: The leader of the NeoTechnos is The HyperMatrix, a powerful Artificial Intelligence that controls the entirety of the NeoTechnos, a robotic society that overthrew their human creators and decided to destroy them. Given that every machine in that society is controlled by the HyperMatrix, the leader choice is pretty obvious, and rebellion was essentially non-existent.
• The Mechanicus Jihad: The Jihad is leaded by The Five, which are the greatest and smartest members of the Jihad, elected in an election where all members participate. The Five have the final word on any decision that is made, but try to gather the general opinion on the matter beforehand.
