The International Order of Rainbow Girls is a Masonic youth organization. It teaches young women, between the ages of 11-20 years of age, leadership training through community service. They learn about the value of charity and service through their work and involvement with their annual local and Grand (state or country) service projects.
It was founded in 1922 by Reverend W. Mark Sexson, a Freemason, was asked to make an address before South McAlester Chapter #149, Order of the Eastern Star, in McAlester, Oklahoma. He had studied the Masonic youth organization for boys: “DeMolay” and he suggested that a similar organization for girls would be beneficial.
Members are expected to serve their community, be law-abiding, acknowledge the authority of the Supreme Assembly, and show loyalty to the other members.
