The Scout movement, also known as Scouting or the Scouts, is a voluntary non-political educational movement for young people open to all without distinction of gender, origin, race or creed, in accordance with the purpose, principles and method conceived by the founder, Lord Baden-Powell. The purpose of the Scout Movement is to contribute to the development of young people in achieving their full physical, intellectual, emotional, social and spiritual potentials as individuals, as responsible citizens and as members of their local, national and international communities. During the first half of the twentieth century, the movement grew to encompass four major age groups for boys (Sigithi Scout, Cub Scout, Boy Scout, Rover Scout) and, in 2008, a new organization, Girl Scout, was created for girls. It is one of several worldwide youth organizations.
