The first Boy Scout encampment concludes at Brownsea Island in southern England.

The Brownsea Island Scout camp was the site of a boys' camping event on Brownsea Island in Poole Harbour, southern England, organised by Lieutenant-General Baden-Powell to test his ideas for the book Scouting for Boys. Boys from different social backgrounds participated from 1 to 8 August 1907 in activities around camping, observation, woodcraft, chivalry, lifesaving and patriotism. The event is regarded as the origin of the worldwide Scout movement.

Up to the early 1930s, Boy Scouts continued to camp on Brownsea Island. In 1963, a formal 50-acre (20 ha) Scout campsite was opened by Olave Baden-Powell when the island became a nature conservation area owned by the National Trust. In 1973, a Scout Jamboree with six hundred Scouts was held on the island.

The worldwide centenary of Scouting took place at the Brownsea Island Scout camp, celebrated on 1 August 2007, the 100th anniversary of the start of the first encampment. Activities by The Scout Association at the campsite included four Scout camps and a Sunrise Ceremony.

A Scout (in some countries a Boy Scout, Girl Scout, or Pathfinder) is a child, usually 10–18 years of age, participating in the worldwide Scouting movement. Because of the large age and development span, many Scouting associations have split this age group into a junior and a senior section. Scouts are organized into troops averaging 20–30 Scouts under the guidance of one or more Scout Leaders or Scoutmasters. Troops subdivide into patrols of about 6–8 Scouts and engage in outdoor and special interest activities. Troops may affiliate with local, national, and international organizations. Some national Scouting associations have special interest programs such as Air Scouts, Sea Scouts, outdoor high adventure, Scouting bands, and rider Scouts.
