Pi Delta Theta

Pi Delta Theta (ΠΔΘ) was a national collegiate sorority operating in the United States from February 14, 1926 until it was absorbed by Delta Sigma Epsilon in September 1941.

History
Prior to formation, the sorority had help in 1925 from the Sorority Service Bureau, whose Mrs. Ida Shaw Martin had been fielding requests for information from recently-formed local sororities seeking some manner of affiliation. She invited representatives of three of these local organizations to send their faculty advisors to a meeting in Boston, Massachusetts in the summer of 1925. Two responded affirmatively, which constitute both the founders and founding chapters of Pi Delta Theta:
 * Mrs. Robert E. Brown, Kappa Theta Alpha (local) of Miami University of Ohio
 * Miss Beulah Houlton, Zeta Sigma Alpha (local) of Kansas State Teachers College, Emporia

The organization was thus formed, with the Miami chapter being named its Alpha chapter, and Mrs. Brown named as the first National President. Expansion began in earnest, but early chapters were lost as the Great Depression dragged on. In 1941, with WWII looming, the four remaining chapters opted for merger.

Pi Delta Theta was a member of the Association of Education Sororities, an NPC predecessor. The merger of Pi Delta Theta and Delta Sigma Epsilon was the only merger to occur within AES organizations.

Fifteen years later, in 1956 Delta Sigma Epsilon would itself merge with Delta Zeta.

Government
Government was vested in three entities: The national convention, the National Council and the Board of Advisers.
