worldwide organization for girls, dedicated to training them in citizenship, good conduct, and outdoor activities. Robert (later Lord) Baden-Powell (Baden-Powell, Robert Stephenson Smyth Baden-Powell, 1st Baron) founded the Girl Guides in Great Britain in 1910 in response to the requests of girls who were interested in the Boy Scout movement established by him in 1908. The first Girl Scout troop in the United States was formed in 1912 by Juliette Gordon Low (Low, Juliette Gordon) of Savannah, Georgia, and followed the pattern set up for the Girl Guides; the organization later adopted the name Girl Scouts of the United States of America. The World Association of Girl Guides and Girl Scouts was formed in 1928.

Aims and activities are substantially the same in all countries in which the movement is organized. The girls promise to follow a code of behaviour, undertake community service projects, and try to develop their skills by earning proficiency badges in a wide variety of activities. In the United States there are five age groups: Daisies (ages 5–6), Brownies (6–8), Juniors (8–11), Cadettes (11–14), and Seniors (14–17). In Great Britain and Australia there are Brownie Guides (7 and over), Guides (10 and over), Ranger Guides (14 and over), and Young Leaders (15–18). The organization's symbol is a golden trefoil.
