Rotary International downtown Chicago, United States, at Harris's friend Gustave Loehr's office in the Unity Building on Dearborn Street on February 23, 1905. In addition to Harris and Loehr (a mining engineer and freemason), Silvester Schiele (a coal merchant), and Hiram E. Shorey (a tailor) were the other two who attended this first meeting. The members chose the name Rotary because initially they rotated subsequent weekly club meetings to each other's offices, although within a year, the Chicago club became so large it became necessary to adopt the now-common practice of a regular meeting place.

Rotary International communist-regime nations were disbanded by 1945–46, but new Rotary clubs were organized in many other countries, and by the time of the national independence movements in Africa and Asia, the new nations already had Rotary clubs. After the relaxation of government control of community groups in Russia and former Soviet satellite nations, Rotarians were welcomed as club organizers, and clubs were formed in those countries, beginning with the Moscow club in 1990. In 1985, Rotary launched its PolioPlus program to immunize all of the world's children against polio. As of 2011, Rotary has contributed more than 900 million US dollars
