CEVAP:

The four types of state systems are identified as independent, hegemonic, imperial, and feudal (Viotti and Kauppi, 2013, 53-99).

1. The independent state system consists of political entities that each claim to be sovereign. No superior power is accepted, but states recognize the claims of independence by other states.

2. The hegemonic state system means that one or more very powerful states dominate the state system. They can constrain the actions of other states and set rules for the world. 

3. The imperial system takes in separate societal units, often empires (in ancient time, very good examples are Macedonia, Assyria, Persia, Rome, and the Ottomans), 

4. The fourth type of international system is the feudal system, which ran from about the 9th through the 14th centuries CE.
