Scouting began in 1907 when Robert Baden-Powell, Lieutenant General in the British Army, held the first Scouting encampment on Brownsea Island in England. Baden-Powell wrote the principles of Scouting in Scouting for Boys (London, 1908), based on his earlier military books, with influence and support of Frederick Russell Burnham (Chief of Scouts in British Africa), Ernest Thompson Seton of the Woodcraft Indians, William Alexander Smith of the Boys' Brigade, and his publisher Pearson.

During the first half of the 20th century, the movement grew to encompass three major age groups each for boys (Cub Scout, Boy Scout, Rover Scout) and, in 1910, a new organization, Girl Guides, was created for girls (today they are called, Brownie Guide, Girl Guide, Girl Scout and Ranger Guide).

The movement employs the Scout method, a program of informal education with an emphasis on practical outdoor activities, including camping, woodcraft, aquatics, hiking, backpacking, and sports. Another widely recognized movement characteristic is the Scout uniform, by intent hiding all differences of social standing in a country and making for equality, with neckerchief and campaign hat or comparable headwear. Distinctive uniform insignia include the fleur-de-lis and the trefoil, as well as merit badges and other patches.
