[1][2] Phi Lambda Chi originated as the Lamb Society, a social fraternal organization formed in 1920 for high school boys.

[3] Aztec's founding members were Thomas Lester Adair, Robert B. Clark, Grant H. Collar, Wendell H. Collums, Marvin Crittenden, Evan M. Douglas, William E. Huddleston, J. Louis Moles, Doyle L. Patton, B. Howard Perrin, Jeff D. Shemwell, and Robert L.

[4] Aztec changed its name to Phi Lambda Chi in 1930 after the college began allowing local Greek letter organizations.

[6] Phi Lambda Chi held its first conclave from March 15 to 16, 1940, at the Arkansas State Teachers College.

[3] Later, the fraternity expanded from its original teacher mission, opening its membership to students from any college or university in the United.

[7][4] In addition, chapters are required to partner with local charities to complete fifteen service hours per member.
