Growth of the Social Fraternity (whose members were informally called the "Oudens") was exponential. By 1838 two-thirds of all students at Williams belonged to the society which engaged in militant agitation against the other two fraternities. One particularly violent incident occurred in 1839 when Oudens assaulted the Kappa Alpha house, driving its occupants to the top of Consumption Hill. More refined conflict took the form of pamphlets and debate. An 1855 debate proposed by Kappa Alpha against the Oudens was called-off after the Social Fraternity appointed

At the 1862 convention, the fraternity's mother chapter, Williams, declared the purposes of the fraternity had been corrupted and, over the objections of the other chapters, withdrew. Two years later it dissolved itself. A chapter would eventually be restored. However, Williams being the first chapter and, therefore, self-chartering, this would come in the form of a new chapter and not the revival of the original. It was permanently erased when Williams College banned all fraternities in 1962.
The March 1864 convention of the A.S.C. saw the organization formally change its name to Delta Upsilon, standardize insignia and ritual throughout all its member chapters, and establish a centralized administrative structure.
Abandoning "anti-secrecy"
In 1879, Delta Upsilon formally disavowed its policy of anti-secrecy, instead adopting a program of what it described as "non-secrecy".
According to Delta Upsilon, the reason for this change was because it had been absolutely victorious in its battle against secrecy, "the character of the secret societies so altered, that hostility toward them decreased".
This explanation has been more skeptically received by some, with one period observer caustically noting that Delta Upsilon "reveals very little more of what it does than the latter
ecret fraternities. Others commented that chapter meetings were closed to all but initiated members and the fraternity was now practicing selective pledging and initiation, in contrast to its earliest days at Williams. Therefore, it was proffered, the description of the fraternity as a "private" society rather than a "non-secret" one might be more accurate. ''

20th century
At the turn of the century the fraternity's growth plateaued due, in part, to opposition from a group of chapters to what was seen as the lessening of the fraternity's standards through colonization.
In 1898, Delta Upsilon joined the recent trend of fraternity expansion into Canada by chartering a chapter at

The turbulence the Greek system experienced in the middle 20th century began for Delta Upsilon in 1956. That year's sitting of the Undergraduate Convention was dissolved by emergency action of DU leadership to "prevent open dissension" in the wake of the election of an African-American as president of the Brown University chapter. The election had been denounced by a number of the fraternity's new southern chapters.
By 1986 Delta Upsilon had 88 active chapters, increasing to a high of 92 in 1991.

21st century
Beginning in 2009 the Fraternity implemented a series of changes that radically reshaped the organization. The fraternity closed a quarter of its chapters for poor performance, including risky behaviors, poor grades, and weak service records. Then it opened a similar number of new chapters under the close guidance of the national organization. The fraternity doubled its staff, from 11 to 22 and added new employees with advanced degrees in higher education or nonprofit management. The fraternity placed an emphasis on the number of members attending educational programming, including international service work and today more than half of undergraduate members participate in at least one educational program per year. Among the chapters targeted for closure was one of the fraternity's longest enduring chapters, the 120-year-old Technology chapter at the

.
Though the shuttering of the Technology chapter was for what fraternity officials would only describe as inappropriate behavior, ''
The Tech'' reported an investigation by Delta Upsilon had allegedly uncovered a prohibited "secret ritual" that had been performed by the chapter for the preceding 70 years. Officers of the Technology chapter, which one account described had a "growing distance from
heinternational fraternity", rejected the charges, though acknowledged they had effectively stopped participating in the fraternity's programs.
In denying an appeal for restoration of the chapter, Delta Upsilon headquarters explained that they had "been working in coordination with university staff" but had been unable to reach a solution by which the chapter could continue at MIT.
On March 28, 2009, Delta Upsilon established its 152nd chapter, and the second of the 21st century, at

existed.
Secessionist chapters
University of Vermont
In 1854 the University of Vermont chapter, which was named
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.
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".)
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.
Harvard University
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.
Delta Upsilon sued its rebellious chapter whose leaders included toy heir
F.A.O. Schwarz Jr. Following the courtroom triumph of the DU headquarters, it expelled the rebellious members and initiated a hand-picked pledge class to continue the chapter.
Its victory was short-lived, though, as the recreated chapter itself voted to disaffiliate from Delta Upsilon. 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. The D.U. Club's alumni board voted to merge its alumni with the
Fly Club

.
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".

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

as chapter president causing the fraternity's new southern chapters to threaten a boycott of the convention.)
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.
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.
"Four Founding Principles"
The Fraternity's Four Founding Principles originated in the Preamble to the early Constitution of the Anti-Secret Confederation. They remained unchanged until the 1891 Convention undertook a complete revision of the Constitution, article-by-article. In the new revision, the old Preamble was completely stricken and the following text was added to Article 1, Section 2: "The objects of this Fraternity shall include the promotion of friendship, the exertion of moral influence, the diffusion of liberal culture, and the advancement of equity in college affairs. It shall be non-secret." This version remained with minor changes until around 1923, when the first printed example of the current version was published in that year's edition of the ''Manual of Delta Upsilon''.
The "Four Founding Principles" are currently: the Advancement of Justice, the Promotion of Friendship, the Development of Character, and the Diffusion of Liberal Culture.

Member misconduct
In 2018, the chapter of Delta Upsilon at the University of Washington in Seattle had its charter revoked for beating pledges and forcing them into servitude of senior undergraduate members. The charter revocation followed its earlier suspension from the university's interfraternity council.
In April 2019, a document was anonymously leaked containing unofficial "minutes" written by members of the Swarthmore College local Phi Psi fraternity between 2013 and 2016. These documents revealed discussion of fraternity activities using racist, sexist, and homophobic language, as well as language condoning sexual assault. These documents also contained the labeling, by the local Phi Psi chapter, of parts of Swarthmore College's Delta Upsilon fraternity house as a "rape attic" and a "rape tunnel". This sparked student activism that led to the voluntary disbandment by unanimous vote of both fraternities shortly thereafter.
