Boy Scouts of America
The Boy Scouts of America were founded by American writer W. D. Boyce, in 1910, but were similar to Scouting groups in Great Britain and other early scout movements. James E. West helped out the BSA in its early years, but also made the BSA more religious than scouts were in Europe.  Scouting grew in the 1910s and 20s due to the rise of “boy’s books” devoted to Scouting and the First World War.  Scouting had many members during the 1960s, but has declined since the 1970s, despite an attempt to make scouting modern by changing requirements and adding more merit badges.
