Phi Gamma Delta, commonly known as Fiji, is a North American social fraternity. The organization was founded in 1848, at Jefferson College in Canonsburg, Pennsylvania.
Initially, chapters of the fraternity were named in the order of the Greek alphabet; the first chapter was designated the Alpha chapter, the second the Beta chapter, and so on. Once the list was exhausted, the second order of chapters had the suffix "Deuteron" to denote this; for example, Alpha Deuteron, followed by Beta Deuteron, and so on. Starting in the late 1880s, the fraternity chapter designations were often references to the local chapters that the fraternity absorbed; for example, the Zeta Phi chapter at William Jewell College is named for the local group which used the name before it was absorbed by the national fraternity. All provisional chapters of the fraternity are referred to as Delta Provisional Chapter before their official chartering.
The modern naming scheme is that a chapter's Greek letters are adapted from the initials of the university's home city or institutional name. For example, the Kappa Tau chapter at the University of Tennessee derives its name from the city of Knoxville, Tennessee, the location of the university, and the Upsilon Alpha chapter at the University of Arizona derives its name directly from the university name itself.
In the fraternity's early days, chapter designations were often reused from closed chapters or chapters at closed or merged institutions. One such example is the Delta chapter at Bucknell University, founded in 1882, the second chapter to use the name; the chapter at Union University formerly used the name before the chapter's closure in 1862. If two institutions merge that both have fraternity chapters, one of the chapter designations will be retired in favor of a single name. This has only happened once in the fraternity's history, when Jefferson College and Washington University merged to form Washington & Jefferson College; the Beta chapter at Washington was retired to consolidate under the Alpha chapter name in use at Jefferson.
