A Nation state is a governing organization which comprises of a number of people, responsible for possessing their own government by occupying a bounded territory and maintaining a national identity.
The nation state system came over when movements like protestant reformation were breaking the back of the Church's power.
At first, this movement aimed to reform the beliefs and practices that were imposed by the Roman Catholic church but soon challenged the absolute power and authority of the pope, which later resulted in the rise of nation-states.
