The Scout Movement was founded by Robert Baden-Powell, a British Army officer, in 1907. He organized an experimental Scout camp on Brownsea Island, England, where he tested his ideas for training young people in outdoor skills, discipline, leadership, teamwork, and self-reliance. His book Scouting for Boys, published in 1908, helped spread the Scouting movement internationally. The movement eventually developed into a worldwide youth organization promoting character development, community service, leadership, and practical skills.
