Slovene National Benefit Society (Slovenska Narodna Podpordna Jednota) was founded in 1904, based on progressive and benevolent principles, to promote Slovenian heritage, fraternalism, and patriotism.

In early times, the society provided life insurance benefits to its members and was a support group for early Slovenian immigrants.  Membership was limited to those of Slovenian ancestry.  Today, as the lodge changes to respond to current times, it continues to uphold the customs and traditions of the past, and membership is open to anyone.

Lodge #11 was founded on September 23, 1904 in Roslyn, WA.  A group of thirteen people met to join SNPJ of Chicago, ILL.  Among them were:  Michael Jakse, Ivan Krebs, Anton Lozekar, Ivan Zobec, Martin Bogataj, Andrej Kocijan, Matija Kocijan, Ivan Malensek, Blax Ceferin, Frank Kunstel, Ignac Mrvar, Frederik Notar, and Anton Janacek.  The Lodge was named SOKOL which means Falcon or Hawk.

On March 4, 1979, a group of twenty-one SNPJ members in Auburn, WA took over the Lodge 11 charter naming it GREATER NORTHWEST SNPJ.  In March, 1980, Lodge 560 of Aberdeen and Hoquiam, WA joined Lodge 11, adding 69 new members.  In January, 1987, Renton Lodge 377 merged with Lodge 11, and later Enumclaw Lodge 783 also merged.  Currently, Lodge 11 has 113 members.
