Which historical event is associated with the early formation of sobriety circles?

The early formation of sobriety circles is most closely associated with the first sobriety "Circles" within Native American tribes. These gatherings served as a traditional and communal practice where individuals could come together to support one another in their journey towards sobriety. This concept of collective support and shared experiences laid the groundwork for later recovery movements that emphasized community and mutual aid, such as Alcoholics Anonymous and other support groups.

The significance of these circles is rooted in the cultural practices of Native American tribes, which often included community rituals and support systems aimed at healing from substance use issues. This historical perspective highlights the importance of community in fostering recovery and the long-standing practices that predate modern approaches to sobriety.

The other historical events listed, while significant in their own right regarding substance use regulations and the fight against substance abuse, do not specifically relate to the concept of sobriety circles and the community-based support systems found within Native American traditions.
