Conflict is a serious disagreement or argument, typically a protracted one between people or  nations.   A strong disagreement can lead to violence.
Violence is the intentional use of physical force or power,
 threatened or actual, against a person, or against a group or 
community, that either results in or has a high likelihood of resulting 
in injury, death, psychological harm, Mal-development or deprivation.  This definition associates intentionality with the committing of the act itself, irrespective of the outcome it produces.
The main causes of conflict may be 
 Individual Difference
Inn society, men are not alike in their nature, 
attitudes,  ideal, interest and aspirations. Due to this difference, 
they fail to  accommodate themselves which may lead to conflict among 
them.
Cultural Difference: Culture is the way of life of
 a group.  It differs from society to society. The culture of one group 
differs from the  culture of the other group. These cultural differences
 among the group,  sometimes cause tension and lead to conflict, example in Ghana the culture of the Ashanti's is different from the Ewe's. 
Clashes of Interests: The clash of interests of 
different  people makes conflict inevitable. The interests of the 
workers clash with the government, hence it leads to strike action on the part of the worker. 
Social Change: Conflict also arises due to the 
difference  between rates of social change. The change in the moral 
norms of a society and  man's hopes, aspirations and demands leads to 
conflict The conflict between the  old and new generations is owing to 
social changes. Conflict is an expression of  social disequilibrium.
Types of conflict
Personal Conflict
Personal conflict occurs on personal level. It arises
 when the aims of two individuals clash with each other. The competition among students who wish to be President of the Student Representative Committee (SRC), or people competing for the same position in the work place
Ethnic Conflict:
Ethnic conflict is mostly due to the physical 
differences. Some  ethnic groups consider themselves superior over other groups and
 there are also ethnic groups which  feel that they are inferior to others. The 
feeling of superiority or inferiority  is the root cause of ethnic 
conflict. 
Political Conflict
Political conflict arises when different political 
parties with  their own ideologies try to achieve their interest. The 
main cause of this kind  of conflict is power which they want to 
capture. Example is the conflict between the New Patriotic Party (NPP) which believes in the capitalist ideology and National Democratic Congress (NDC) which is a social Democrats and their current conflict over votes in the 2012 general election is an example. 
Conflicts can be resolved in different ways such as Family, religion, Traditional, national and international bodies.   In Ghanaian society, family is the highest priority of every one, to keep the family bond together by being keepers of each other, therefore conflicts are and can be resolved the by family head, who brings the two parties involved in the conflict to a hearing by the family leaders, this is to ascertain the cause or the source of the conflict.  The leaders on hearing each side will meet separately to analyse critically the issues and then bring their verdict.  One important thing to note is that family unity and bond supersede individual interest and should not be broken by any member.
Conflict can also be resolve by religious leaders.  They base their argument on the religious beliefs of the parties and the fact that we must live in peace with all men.  No religion advocates for conflicts that can degenerate to violence.
Traditional chiefs are more important than ever before. While neglected 
and without real administrative authority, traditional leaders now works
 hand in hand with politicians for conflict resolution, through mechanisms and methods hitherto only applied in the 
traditional context.  In Ghana there is a traditional court in Ghana that help to resolve issues such accommodation, marital and family conflicts that proves difficult to solve by the family heads. 
Conflict are not healthy in which ever environment it occurs, either t work place, home, church, town, city or a nation.
A strong disagreement can lead to violence if not resolved properly 
hence creating a bad living condition for people. It can lead to 
instability, increased stress, reduced productivity, and in some cases 
sickness like hypertension.  It can lead to negative impact on children’s mental health, poor role-modeling for children, timidity, children worry about taking sides hence leads to wayward children.
Let us avoid conflict by learning to resolve our differences.
