Rotary is an international service organisation with over 1.2 million men and women members worldwide. It is structured around individual clubs operating in their local area. The main object of the clubs is to support good causes and community projects, both in their local area and internationally. To do this they organise fund raising events, as well as providing direct, hands on support for these causes. The clubs have a strong fellowship element, with numerous social events, so they provide their members with much enjoyment, while at the same time enabling them to give something back to the community.

The clubs meet on a regular basis, usually over a meal, which could be breakfast, lunch or dinner, depending on the club. Some meetings are used to review the club's service and social activities, although at most there will be a guest speaker, the subject of which can be anything at all.

Individual clubs manage their own affairs by appointing a President each year. He/she is supported by a council, which is also elected on an annual basis. Typically, each council member will have responsibility for overseeing one aspect of the club's activities.

The clubs are organised into districts, which are ultimately part of the overall Rotary International ("RI") organisation.  Founded in 1905, RI has significant power derived from its large membership. It operates its own charity, the Rotary Foundation, and engages in major international projects, such as the eradication of polio. The main symbol of the organisation is the Rotary Roundel, shown in the top left hand corner of this page. Rotary Clubs in the UK and Ireland have their own governing body named Rotary International in Great Britain and Ireland (RIBI). On the RIBI website there are many links to videos expalining what Rotary does.

Rotarians live by a code of high ethical standards and carry the creed of international goodwill and peace throughout all aspects of their personal, business and community lives.
