Growth

The Boy Scout movement swiftly established itself throughout the British Empire soon after the publication of Scouting for Boys. The first recognized overseas unit was chartered in Gibraltar in 1908, followed quickly by a unit in Malta. Canada became the first overseas dominion with a sanctioned Boy Scout program, followed by Australia, New Zealand and South Africa. Chile was the first country outside the British dominions to have a recognized Scouting program. The first Scout rally, held in 1909 at The Crystal Palace in London, attracted 10,000 boys and a number of girls. By 1910, Argentina, Denmark, Finland, France, Germany, Greece, India, Malaya, Mexico, the Netherlands, Norway, Russia, Sweden, and the United States had Boy Scouts.
The program initially focused on boys aged 11 to 18, but as the movement grew, the need became apparent for leader training and programs for younger boys, older boys, and girls. The first Cub Scout and Rover Scout programs were in place by the late 1910s. They operated independently until they obtained official recognition from their home country's Scouting organization. In the United States, attempts at Cub programs began as early as 1911, but official recognition was not obtained until 1930.
Girls wanted to become part of the movement almost as soon as it began. Baden-Powell and his sister Agnes Baden-Powell introduced the Girl Guides in 1910, a parallel movement for girls, sometimes named Girl Scouts. Agnes Baden-Powell became the first president of the Girl Guides when it was formed in 1910, at the request of the girls who attended the Crystal Palace Rally. In 1914, she started Rosebuds – later renamed Brownies – for younger girls. She stepped down as president of the Girl Guides in 1920 in favor of Robert's wife Olave Baden-Powell, who was named Chief Guide (for England) in 1918 and World Chief Guide in 1930. At that time, girls were expected to remain separate from boys because of societal standards, though co-educational youth groups did exist. By the 1990s, two thirds of the Scout organizations belonging to WOSM had become co-educational.
Baden-Powell could not single-handedly advise all groups who requested his assistance. Early Scoutmaster training camps were held in London in 1910 and in Yorkshire in 1911. Baden-Powell wanted the training to be as practical as possible to encourage other adults to take leadership roles, so the Wood Badge course was developed to recognize adult leadership training. The development of the training was delayed by World War I, so the first Wood Badge course was not held until 1919. Wood Badge is used by Boy Scout associations and combined Boy Scout and Girl Guide associations in many countries. Gilwell Park near London was purchased in 1919 on behalf of The Scout Association as an adult training site and Scouting campsite. Baden-Powell wrote a book, Aids to Scoutmastership, to help Scouting Leaders, and wrote other handbooks for the use of the new Scouting sections, such as Cub Scouts and Girl Guides. One of these was Rovering to Success, written for Rover Scouts in 1922. A wide range of leader training exists in 2007, from basic to program-specific, including the Wood Badge training.
