Marriage is defined differently, and by different entities, based on cultural, religious and personal factors. 

Our definition of marriage: A formal union, marriage is a social, and legal contract between two individuals that unites their lives legally, economically, and emotionally. The contractual marriage agreement usually implies that the couple has legal obligations to each other throughout their lives or until they decide to divorce.

 Being married also gives legitimacy to sexual relations within the marriage. Traditionally, marriage is often viewed as having a key role to the preservation of morals and civilization.
