Rotary is an opportunity to build lifelong friendships and experience the personal satisfaction of providing volunteer service to others.

The world's first service club, the Rotary Club of Chicago, Illinois, USA, was formed on 23 February 1905 by Paul P. Harris, an attorney who wished to recapture in a professional club the same friendly spirit he had felt in the small towns of his youth. The name "Rotary" derived from the early practice of rotating meetings among members' offices.

Rotary's popularity spread throughout the United States in the decade that followed; clubs were chartered from San Francisco to New York. By 1921, Rotary clubs had been formed on six continents, and the organization adopted the name Rotary International a year later.
