Scouting began in England in 1907, based on the ideas of founder Sir Robert S.S. Baden-Powell and his book Scouting for Boys. The book and program proved to have universal appeal for boys and quickly spread worldwide. The Scouting program spread around the world until it became what it is now—the largest voluntary youth movement in the world, with a membership of more than 40 million. A member of the World Organization of the Scout Movement, the Boy Scouts of America was incorporated on February 8, 1910, by W.D. Boyce. Through the BSA’s International Department, American Scouts and international Scouts are provided a common resource of programs, funding, and training that increases and enhances their experience in the brotherhood of Scouting.
