George Simmel has distinguished four types of conflict 

1. War 

2. Feud or rational strife 

3. Litigation 

4. Conflict of impersonal ideas.

1. War: according to Simmel war represents a deep seated antagonistic impulse in men. But to bring out this impulse into action some define objectives is needed. The objective may be the desire to gain material interests. 

2. Feud and factional strife: this is an intra-group conflict. It may arise because of injustice alleged to have been done by one group to another.

3. Litigation: Litigation is ajudicial form of conflict. It is ajudicial struggle by an individual or group to protect right to possessions. This kind of conflict is more objectives in nature. 

4. Conflict of impersonal ideas: This is a conflict carried on by the individuals not for themselves but for an ideal. In such a conflict each party attempts to justify truthfulness of its own ideas. For ex, the communists and Capitalists carry on conflicts to prove that their own system can bring in a better world order.
