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.)
