Conflict may be defined as an incompatibility between aims or desires held by at least two parties within a social system. A party may be a person, a family, or a whole community; or it may be a class of ideas, an organization, an ethnic group, or a religion. Some of the causes of conflict are to be found in the aggressive behaviour that is almost universal among vertebrates.
Conflict also has a positive function in helping to focus on what is really required in contrast to what is not really needed. Conflict can bring people closer together as they work to resolve their differences in a spirit of cooperation and positive intent.
