Phi Lambda Alpha (ΦΛΑ) was established in 1919 at the University of California, Berkeley.^[1] It was the first Latin American–based Greek lettered collegiate fraternity in the Western United States.

Phi Lambda Alpha fraternity established communications with Pi Delta Phi, which had been recently founded in 1916 in the Northeastern United States at Massachusetts Institute of Technology. After some communication, these two organizations realized the existence of a non-Greek letter secret society, the Union Hispano Americana (UHA). As a result of intensive correspondence and various interviews, the three organizations merged. In their merger agreement, the three organizations adopted the name of Phi Lambda Alpha Fraternity, with the distinctive emblem and constitution of Pi Delta Phi, and the goals & motto of the UHA. This new union was formalized on June 11, 1921, in the City of New York.

After Phi Lambda Alpha was organized, other societies joined it: the Club Latino-Americano founded in 1919 at Colorado School of Mines; the Federación Latino-Americana founded in 1926 at Columbia University joined in 1928; the Club Hispania founded in 1929 by Cornell University which joined in 1931; the Club Hispano-Americano founded in 1921 of Tri-State College in Angola which joined in 1929 and the Alfa Tenoxtitlan Militant chapter founded in 1929 by members of the old ΦΛΑ in Mexico.^[2]

On December 26, 1931, Phi Lambda Alpha merged with Sigma Iota fraternity to form Phi Iota Alpha. Phi Sigma Alpha fraternity can also trace its roots back to Phi Lambda Alpha.
