Editing Delta Upsilon (section)

===Secessionist chapters===

====University of Vermont====
In 1854 the University of Vermont chapter, which was named [[Delta Psi (University of Vermont)|Delta Psi]], severed its connections with the Anti-Secret Confederation. The cause of separation is lost to history with Delta Upsilon's own records recording that the exit of Delta Psi is "from causes unknown to us". A Delta Psi historian later claimed the withdrawal was due to the expenses the fraternity was incurring sending delegates to the meetings of the Anti-Secret Confederation.<ref name="six" /><ref name="hund">{{cite book |last=Miller |first=Thomas |date=1934 |title=Delta Upsilon One Hundred Years 1834-1934 |publisher=Delta Upsilon }}</ref> It has also been speculated that Delta Psi felt local pressure in maintaining the A.S.C.'s militant stance against secret ritual; after separating from the A.S.C. it began to undertake secret work. (Delta Upsilon has maintained that it does not consider members of Delta Psi during the period it was affiliated with the A.S.C. to also be members of Delta Upsilon, the separation being so total that the "action removed all its members from membership in the Delta Upsilon fraternity".)<ref name="thomas">{{cite book |last=Thomas |first=John |date=2005 |title=University of Vermont |publisher=Arcadia |page=30 |isbn=0738537772 }}</ref><ref name="DU">{{cite book |last=Chase |first=William |date=1884 |title=The Delta Upsilon Quinquennial Catalogue |publisher=Delta Upsilon |page=320 }}</ref>

Delta Psi continued as a very successful local fraternity for 150 years after leaving Delta Upsilon. During this period, DU avoided attempts to colonize the University of Vermont. In 2014, ten years after the collapse of Delta Psi, Delta Upsilon entered the Burlington campus for the first time since its split with Delta Psi, chartering a colony.<ref>{{cite news|last=Olsen |first=Sarah |date=30 September 2014 |title=New Fraternity to Join UVM |url=http://www.vtcynic.com/2014/09/new-fraternity-to-join-uvm/ |newspaper=The Vermont Cynic |location=[[Burlington, VT]] |access-date=12 December 2014 |url-status=dead |archive-url=https://web.archive.org/web/20141213061113/http://www.vtcynic.com/2014/09/new-fraternity-to-join-uvm/ |archive-date=13 December 2014 }}</ref>

====Harvard University====
[[File:Fly Club, Harvard University, 2009.jpg|thumb|right|Delta Upsilon's first Harvard chapter revolted, disaffiliated, and ultimately merged with the Fly Club, whose clubhouse is pictured. A more recent colonization attempt proved similarly disastrous.]]
When the fraternity incorporated in 1909 it adopted a new constitution. The Harvard chapter immediately set-forth its views that the new constitution had been illegitimately enacted and had overly vested control in the professional leadership, undermining the ability of the chapters to democratically express themselves. Though a number of other chapters initially signaled support for the Harvard position, a proposed amendment to the new document failed. In 1915 the Harvard chapter stopped paying dues to the fraternity. A further shot across the bow of the international fraternity came when Harvard requested headquarters stop sending copies of the ''Delta Upsilon Quarterly'' because they "littered up the house". Open revolt came when the international fraternity tried to impose discipline on Harvard. Harvard responded by declaring it didn't recognize the authority of DU headquarters as Delta Upsilon had ceased to exist in 1909.<ref name="hund" /> Delta Upsilon sued its rebellious chapter whose leaders included toy heir [[F.A.O. Schwarz Jr.]]<ref>{{cite news |date=18 March 1924 |title=D. U.

The secessionist group legally reconstituted itself as "the D.U. Club", taking the chapter roll book with them, and existed as a successful [[finals club]] for many decades on the Harvard campus. In 1995, the D.U. Club closed after an assault of a football recruit occurred at its clubhouse.<ref>{{cite journal |author=Jonathan A.

After several decades of patient waiting for the D.U. Club to pass, Delta Upsilon chartered yet another chapter at Harvard. The new chapter was installed in 1999, four years after the D.U. Club had merged with the Fly Club. It unraveled faster than its predecessors, however. In 2005 the six-year-old Delta Upsilon chapter voted to disaffiliate from the fraternity. It has continued under the name "Oak Club" and currently claims more than 100 alumni who, it says, embody "many of the original DU principles".<ref>{{cite web |url=http://www.theoakclub.org/history |title=History |website=theoakclub.org |publisher=The Oak Club |access-date=16 December 2014}}</ref>

====Bowdoin College====

Delta Upsilon's chapter at [[Bowdoin College]] disaffiliated in the 1950s, reforming as a local known as Delta Sigma. The decision came after the chapter had admitted a black Bowdoin student as a member and was ordered by DU Headquarters to dismiss him. The chapter chose instead to disaffiliate.

====Brown University====

Delta Upsilon's chapter at [[Brown University]], which was organized in 1868, disaffiliated in 1967, reforming as a local known as Kappa Delta Upsilon (so named because it was the tenth chapter of Delta Upsilon and Kappa is the tenth letter of the Greek alphabet). The decision came after a decade of strained relations with the DU headquarters, originating in its decision to declare an emergency and dissolve the 1956 sitting of the Undergraduate Convention, a move it said was necessary to "prevent open dissension". (The preceding year, the Brown DU chapter had elected an [[African-American]] as chapter president causing the fraternity's new southern  chapters to threaten a boycott of the convention.) <ref name="bdh">{{cite news |last=Naline |first=Lai |date=7 February 1986 |title=KDU is Now Delta Upsilon |url=http://library.brown.edu/cds/dbdh/bdh_render.php?issue=1236283767342537&div=DIVL147&pid=0 |newspaper=Brown Daily Herald }}</ref><ref name="BROWN" /><ref name="DUQa">{{cite news |date=January 1986 |title=The President's Report |url=http://issuu.com/deltaupsilon/docs/quarterlywinter1986 |newspaper=Delta Upsilon Quarterly }}</ref>

Almost 20 years later, in 1986, the Brown chapter rejoined Delta Upsilon. Terry Bullock, then Delta Upsilon international president, wrote of the return of Brown that "there is no greater joy than the reconciliation of a family estranged for many years". The joy was short-lived, however, as the chapter again voted to disaffiliate in 1991, reverting to the name Kappa Delta Upsilon.<ref name="BROWN">{{cite web |url=http://www.brown.edu/Administration/News_Bureau/Databases/Encyclopedia/search.php?serial=F0270 |title=Brunoniana |website=brown.edu |publisher=[[Brown University]] |access-date=20 December 2014}}</ref><ref name="DUQa" /> In 1996 Kappa Delta Upsilon was banned from campus for 5 years due to the circumstances surrounding a fire in its basement. It has yet to reestablish itself.<ref>{{cite news |date=February 1996 |title=Since Last Time |url=https://archive.org/stream/brownalumnimonth969brow#page/n3/mode/2up |newspaper=Brown Alumni Monthly }}</ref><ref>{{cite web|url=http://www.brown.edu/Student_Services/Greek_Council/houses |title=Greek Houses |website=brown.edu |publisher=Brown University Greek Community |access-date=20 December 2014 |url-status=dead |archive-url=https://web.archive.org/web/20141221074129/http://www.brown.edu/Student_Services/Greek_Council/houses |archive-date=21 December 2014 }}</ref>
