According to Prof Gettel, main features of evolution of state are as under:
1. State has developed from simple to complex. Initially, the structure of state was very simple, which became complex with the development of human life.
2. Initially, number of states was very less and area was limited, but gradually jaulation and area increased.
3. With the development of political awareness among people along with the development of state, (systems like) representative democracy and feudal government originated.
4. There were autocratic monarchies in the beginning of the development of states where individual freedom had no place. Gradually, importance of individual freedom increased, and compromise between the sovereignty of state and individual freedom was accepted.
5. In the beginning, state and religion were connected, but presently, they are separated from each other. Today the concept of secular state is prevalent.
