Force theory of origin of state means that the basis of origin of sate is force. In every state, there had been the governance of the stronger on the weaker. Supporters of force theory believed that origin and development of state was possible only because of force. When the universe began, then groups of men used to wander here and there in search of food.
These groups often fought with each other, and when the stronger groups had their right on the weaker groups, then the state originated because the leader of the stronger group became the king and made the defeated group his subjects. Leacock, the political thinker, has explained the force theory as under:
“Historically, it means that governance is result of human attack. State originated because of making one man slave by the other and triumph of a stronger tribe on the weaker. Generally, when an individual took another under his control by the superior moral power to fulfil his own selfishness, then the state was originated. For this reason, state developed from tribes and the empires developed gradually from state”.
