The Scout Association is a council that registers local Scout groups, which "are autonomous charities affiliated to The Scout Association". The organisation and its affiliated local groups have the largest enrolment within the Scout Movement in the United Kingdom. Following the rapid development of the Scout Movement from 1907, Robert Baden-Powell formed an advisory council in 1910, which was incorporated by a royal charter in 1912 under its previous name of The Boy Scouts Association. It is a founding member organisation of the World Organization of the Scout Movement.
