From Miami University's
Cliff Alexander Office of Fraternity and Sorority Life and Leadership Community.
"In 1809, Miami University received its charter from the State of Ohio. Instruction began in 1824.
It was in 1833 when the university saw it's first fraternity, Alpha Delta Phi. Since then, Miami University has experienced a long history of fraternal life on campus for nearly 170 years. Five social Greek-lettered organizations have their origins here at Miami University: Beta Theta Pi (1839), Phi Delta Theta (1848), Sigma Chi (1855), Delta Zeta (1902), and Phi Kappa Tau (1906)."
