History

AA sprang from The Oxford Group, a non-denominational movement modeled after first-century Christianity. Some members founded the Group to help in maintaining sobriety. "Grouper" Ebby Thacher was Wilson's former drinking buddy who approached Wilson saying that he had "got religion", was sober, and that Wilson could do the same if he set aside objections to religion and instead formed a personal idea of God, "another power" or "higher power".

Feeling a "kinship of common suffering" and, though drunk, Wilson attended his first Group gathering. Within days, Wilson admitted himself to the Charles B. Towns Hospital after drinking four beers on the way—the last alcohol he ever drank. Under the care of William Duncan Silkworth (an early benefactor of AA), Wilson's detox included the deliriant belladonna. At the hospital, a despairing Wilson experienced a bright flash of light, which he felt to be God revealing himself. Following his hospital discharge, Wilson joined the Oxford Group and recruited other alcoholics to the Group. Wilson's early efforts to help others become sober were ineffective, prompting Silkworth to suggest that Wilson place less stress on religion and more on "the science" of treating alcoholism. Wilson's first success came during a business trip to Akron, Ohio, where he was introduced to Robert Smith, a surgeon and Oxford Group member who was unable to stay sober. After thirty days of working with Wilson, Smith drank his last drink on 10 June 1935, the date marked by AA for its anniversaries.

The first female member Florence Rankin joined AA in March 1937, and the first non-Protestant member, a Roman Catholic, joined in 1939. The first Black AA group was established in 1945 in Washington, D.C. by Jim S., an African-American physician from Virginia.

During the COVID-19 pandemic, many AA meetings moved to online meetings using platforms such as Zoom, Google Hangouts, and conference calls. Some members expressed concerns about anonymity and security and steps were taken, including having "digital bouncers" at some online meetings.
