Lord Robert Baden Powell founded the scouting movement in 1907 when he brought 20 boys to Brownsea Island to test his ideas. He published a book on scouting in 1908 and held the first scout rally in 1909 at Crystal Palace in London. Baden Powell was proclaimed chief scout in 1920 and devoted the rest of his life to growing the scouting movement globally. Scouting began in the Philippines in 1939 under Josefa Llanes Escoda and continued operating through World War 2, with the first Philippine troop registering under the US located in Davao.
