The term brotherhood is the one used to designate that bond that is established between siblings and that is normally characterized by feelings such as affection, empathy, compassion, accompaniment, etc. Brotherhood is one of the deepest relationships that a person can develop throughout his life and because it is established around blood ties, it is a relationship that remains eternally even though the person does not know or do not maintain constant contact with those who fulfill the role of their brothers. Brotherhood, based on this idea, is also understood as any union of people that is based on similar feelings and that involves complete surrender and commitment to the other.
The brotherhood or fraternity is a type of bond that is born at the moment in which a person becomes brother of another. This natural act, which assumes that two or more people are children of the same individuals, is extremely common. However, this does not mean that all people experience a sibling relationship since you can be an only child and never have siblings.
The idea of brotherhood supposes, as it was said, a set of acts, ways of acting or responding that are based on feelings of mutual commitment, identification, accompaniment, solidarity and affection. Obviously, each particular relationship will mean different ways of expressing these feelings towards the other.
It is precisely on the idea of what brotherhood represents on a physical and biological level that the concept of brotherhood is established in an abstract way. Thus, many social institutions are understood as brotherhoods (for example, educational institutions, lodges, religious institutions, political parties, etc.) and are organized around this same notion of solidarity, identification with similar ideals and values, company, commitment, affection and constant contact with the other.
