is an ethnic fraternal benefit and social organization for Slovene immigrants and their descendants in the United States.
The incorporation was delayed over a year because of an Illinois law which required fraternal benefit groups to have at least 500 members.
In 1917 the SNPJ, with 16,700 members in 360 lodges, had become the largest Slovene fraternal benefit society in the United States.
[citation needed] Just over twenty years later, in 1969, the Slovene Independent Benefit Society merged with SNPJ.
[citation needed] Thirty-two years after that merger, in 2001, the Workingmen's Beneficial Society of Pittsburgh merged with SNPJ.
[9] The local chapters of the Society are called "Lodges" and the supreme authority is the "National Legislative Body", which meets quadrennially.
A prospective member must promise to be faithful to the Society's constitution, defend the reputation of the lodges, and bring no harm to the organization.
