Fraternities are usually formed with different guidelines and purposes, although they may just be for fun. Fraternities will generally help out in their community and organize events that will bring them together to do something to help the area.[citation needed] They will have some fundraisers and parties, but you could still be removed from the fraternity if you violate their rules or don't live up to their expectations.
Fraternities also help people get jobs and meet people.

A fraternity (Latin frater : "brother") is a brotherhood, though the term usually connotes a distinct or formal organization. The only true distinction between a fraternity and any other form of social organization is the implication that the members freely associate as equals for a mutually beneficial purpose, rather than because of a religious, governmental, commercial, or familial bond, although there are fraternities dedicated to each of these topics.[1]

In many instances fraternities are limited to male membership but this is not always the case, and there are mixed male and female, and even wholly female, fraternities. For example, for general fraternities; Grande Loge Mixte de France, Honorable Fraternity of Ancient Freemasons, Grande Lodge Feminine de France, Order of the Eastern Star, Order of DeMolay; for college and university fraternities, Delta Chi, Sigma Phi Epsilon, Kappa Alpha Theta, Alpha Phi International, Pi Kappa Phi, Delta Delta Delta, Beta Theta Pi, and Knights of Phi Lambda Sigma-ΦΛΣ 1914.

Fraternities can be organized for many purposes, including university education, work skills, ethics, ethnicity, religion, politics, charity, chivalry, other standards of personal conduct, asceticism, service, performing arts, family command of territory, and even crime. There is almost always an explicit goal of mutual support, and while there have been fraternal orders for the well-off there have also been many fraternities for those in the lower ranks of society, especially for national or religious minorities. Trade unions also grew out of fraternities such as the Knights of Labor.
