Soon after founding the Scout movement, Robert Baden-Powell saw the need for leader training. Early Scoutmaster training camps were held in London and Yorkshire. Baden-Powell wanted practical training in the outdoors in campsites. World War I delayed the development of leader training, so the first formal Wood Badge course was not offered until 1919.

Gilwell Park, just outside London, was purchased specifically to provide a venue for the course and the Opening Ceremonies were held on July 26, 1919. Francis Gidney, the first Camp Chief at Gilwell Park, conducted the first Wood Badge course there from September 8–19, 1919. It was produced by Percy Everett, the Commissioner of Training, and Baden-Powell himself gave lectures. The course was attended by 18 participants, and other lecturers. After this first course, Wood Badge training continued at Gilwell Park, and it became the home of leadership training in the Scout movement.
