During formation, the Knights of Classic Lore were trying to get the Illinois Epsilon chapter of Phi Delta Theta restored. Prominent Phi Delt alumnus Richard Henry Little became a persistent sponsor for the Knights to petition Phi Delta Theta for a charter. The Knights first petitioned Phi Delta Theta at its 1902 convention in New York, but efforts were unsuccessful. After renting rooms at several locations beginning in the spring of 1899, the Knights of Classic Lore finally acquired its first fraternity house, known as The Wilder Mansion, in September 1902. Simultaneously with the acquisition of the new house, the Knights also adopted the name Tau Kappa Epsilon. The change in name was expected to create a better impression in future petitions to Phi Delta Theta. The second petition was presented at the Indianapolis convention of 1904, but it was withdrawn in an effort to gain unanimous support of all chapters in Phi Delta Theta's Zeta Province, which included Colorado, Illinois, Iowa, Kansas, Nebraska, Minnesota, and Wisconsin. If this support was achieved, then the charter would be granted to the group without any action from the convention. The Knights of Classic Lore gained the support of all Phi Delta Theta groups in the province, except for Wisconsin Alpha, Illinois Beta, and Missouri Alpha. The Knights in turn unsuccessfully presented the petition at the 1906 convention in Washington, D.C. During the continuing struggle for acceptance from Phi Delta Theta, TKE continued to grow stronger in its own existence.
