Why is it typically so difficult to centralize the government of a country or area made up of different tribes and clans

It is typically difficult to centralize the government of a country or area made up of different tribes and clans because different tribes and clans bear different ideologies and have varied beliefs. Moreover, they are not used to lead a life under someone else's political dominance.

Explanation:

Tribes and clans are majorly orthodox groups of people that identify themselves with their culture and tradition. Each tribe or clan is a closed isolated community which has its own way of leading life. These tribes and clans don't like third-party interference in their tradition and culture. Hence, it is difficult to centralize the government of a country made up of different tribes and clans.
