The 12 Principles of AA is essentially the work of AA’s founders, but early in AA’s history, the organization listed six principles, many of which were influenced by the founders’ experience with The Oxford Group. By 1939 and the publication of The Big Book, Wilson and Smith revised their principles, expanding them to reflect their work and its progress. AA is, of course, heavily focused on principles of Christianity, but many of today’s groups have modernized the tenets to reflect a more diverse audience. Even so, the 12 Principles of AA have remained its central guiding influence. Many people suffering from alcoholism continue to find success in recovery by participating in AA’s program.
