Brunswick County was named for the duchy of Brunswick-Lunenburg, one of the German possessions of George I. It was formed in 1720 from Prince George County, but, because of the sparse population, county government was not organized until 1732. In the latter year Brunswick County was enlarged by the addition of parts of Surry and Isle of Wight Counties.

The Sons of Temperance, a total abstinence society, was founded in New York in 1842. The fraternal order provided assistance for its members, both in remaining temperate, and as a mutual aid society. More broadly, they promoted the societal benefit of abstinence and temperance. In contrast to its immediate predecessor, the Washington Movement, the Sons recruited members from among those already well affected to their cause. Though they refrained from taking public stances on religious and political matters, they did advocate ending the temptation by stopping the production and sale of alcohol. As a mutual aid society, the Sons of Temperance doled out sickness and disability benefits and allotted money to assist with the burial of fellow brothers and their wives. The attractiveness of its benefits led the organization to operate as a secret society, with stringent rules and a highly restricted membership. Allegations of intemperance and other transgressions were routinely investigated and often led to expulsion from the organization.
