Back in the early 60’s I earned BSA Citizenship in the Community and Citizenship in the Nation.
The requirements may give some ideas. Reqs. changed about 2005 and Citizenship in the World was added. (Probably messed things up.)
I would look for the 1952 version.
And I will google around some. If I were do dig in one of my archival ‘areas’ I might find my BSA Manual with them???
Quick look for BSA Merit Badges:
