# List of Zeta Psi chapters

This article had claimed the chapter to be the "First modern Greek letter fraternity in the UK." &#x2D;&#x2D;I do not believe this to be true, there were several others during the American Civil War.Each chapter in Zeta Psi has a unique name composed of one or two Greek letters. A colony petitioning Zeta Psi to become a chapter chooses a name for its chapter upon receiving its charter. From this point on, the name is fixed. Even if the chapter goes inactive—in that it has no undergraduate members—the name will be taken up by any group that re-establishes a chapter at the university campus.
The name can be based on many different factors. For instance, it is common for new chapters to take on an element from an existent chapter that has helped them form. Theta Xi chapter in Toronto adopted the Xi from their neighbor chapter in Michigan. In turn, every chapter in Ontario has a "Theta" as part of their name from their relationship to the Toronto chapter. Other times, a name is related to other factors like the Roman Catholic Villanova University chapter being named Alpha Omega chapter due to the Christian significance.
A one or two-letter name can only be re-used if the chapter possessing the name is pronounced "deceased." This has not happened since 1892.

### Explanatory notes

* ↑ The original Zeta chapter withdrew from ΖΨ in 1852 to join Delta Psi in 1853 where it became the Lambda chapter of that fraternity. ΖΨ re-established its chapter at Williams in 1881, by absorbing Phi Gamma Delta's original Iota chapter on that campus, which had formed in 1880, but which had withdrawn from that national one year later. This all occurred before the development of the NIC, which prohibited much of the poaching that had occurred in earlier years.
* ↑ Greek letter organizations are banned at Williams, though there have been reports of sub rosa chapters of another fraternity.
* ↑ Renamed Omicron Epsilon chapter on the same campus after the long dormancy.
* ↑ This chapter originated as Alpha Omega (local) in 1849.
* ↑ Greek letter organizations are banned at Colby.
* ↑ The former Epsilon chapter of Zeta Psi went co-ed, renaming itself Zeta Delta Xi on January 24, 1987.
* ↑ In its 1919 reorganization, this chapter absorbed Delta Gamma Psi (local), formed earlier that same year.
* ↑ Chapter closed due to the loss of its members in the Civil War.
* ↑ At the beginning of the Civil War, all but two of Michigan's Beta chapter active members left campus to enlist in the Union or Confederate armies. The brotherhood in Ann Arbor was subsequently reorganized under a new name with the chartering of the Xi chapter in 1861 and morally supported by the efforts of Elders Lewis Pilcher and James F. Spalding. However, this new Xi chapter's founding is officially recorded in Fraternity history as occurring in 1858. It was founded through the efforts of Liberty Emery Holden, a transfer from Chi chapter at Colby College. The later use of the name Beta chapter at Virginia was unrelated to the Michigan group, whose use of that name only lasted a few years.
* ↑ Greek letter organizations are banned at Amherst.
* ↑ Charter "moved" to Rensselaer after Civil War.
* ↑ In its 1885 revival, this chapter absorbed Rho Sigma Tau (local) formed earlier that year.
* ↑ Xi chapter operations suspended through end of 2021.
* ↑ This school was closed after the school was destroyed during the Civil War, on November 15, 1864.
* ↑ This chapter died with the Institute's demise following the Civil War.

* ↑ This chapter originated as the Cuardrumas Club (local), before 1864.

* ↑ The charter for this chapter was moved from Amherst College after the Civil War.
* ↑ The use of the name Beta chapter at Virginia is wholly separate from that name's earlier short-term usage at Michigan.
* ↑ Fraternities were banned at the US Naval Academy in the late 1800's. The school only briefly had three: ΒΘΠ, ΖΨ and ΚΣ. All three were closed within a year or two of chartering, none surviving past 1887.
* ↑ Closed due to "government restrictions against fraternities".
* ↑ This chapter originated on the Syracuse campus as Theta Chi (local) in 1874. No relation to the national fraternity of that same name, which only had one chapter at the time.
* ↑ The chapter letter name Mu was originally given to the chapter but changed to Alpha a few years later with permission of the Grand Chapter in January 1882

* ↑ This chapter originated as Alpha Theta Epsilon (local) in 1913.
* ↑ This chapter originated as the Hexagon Club (local) in 1919.
