A club is an association of two or more people united by a common interest or goal. A service club, for example, exists for voluntary or charitable activities; there are clubs devoted to hobbies and sports, social activities clubs, political and religious clubs, and so forth.
Historically, clubs occurred in all ancient states of which we have detailed knowledge. Once people started living together in larger groups, there was need for people with a common interest to be able to associate despite having no ties of kinship. Organizations of the sort have existed for many years, as evidenced by Ancient Greek clubs and associations (collegia) in Ancient Rome.
It is uncertain whether the use of the word "club" originated in its meaning of a knot of people, or from the fact that the members “clubbed” together to pay the expenses of their gatherings. The oldest English clubs were merely informal periodic gatherings of friends for the purpose of dining or drinking with one another. Thomas Occleve (in the time of Henry IV) mentions such a club called La Court de Bonne Compagnie (the Court of Good Company), of which he was a member. In 1659 John Aubrey wrote, “We now use the word clubbe for a sodality [a society, association, or fraternity of any kind] in a tavern.”
Of early clubs the most famous, latterly, was the Bread Street or Friday Street Club that met at the Mermaid Tavern on the first Friday of each month. John Selden, John Donne, John Fletcher and Francis Beaumont were among the members (although it is often asserted that William Shakespeare and Sir Walter Raleigh were members of this club, there is no documented evidence to support this claim). Another such club, founded by Ben Jonson, met at the Devil Tavern near Temple Bar, also in London.
