The atmosphere of Ondo was still saturated with trouble and chaos when Oba Osungbedelola ascended the throne (A.D. 1870). Unfortunately, the trouble which had loomed for so long broke into the open, and as a result the grave disorder and strife that followed, the Ondo fled the town and sought shelter and peace in places like Igbado, Erinla, Ajue, Oke-Opa, etc.

(January 13) The Ondo Boys High School was, easily the first Community Grammar School “from Sierra Leone down to Nigeria here”. It started as C. M. S. Grammar School in St. Stephens’ Vicarage, Ondo, on January 13,
1919. Twenty-six students were enrolled that day. The Late Mr.(later Bishop) D. O. Awosika and the Late Mr. S. R. Fadase – both of them sons of the soil, were the first tutors. Mrs. V. O. Akinrele (nee Akinkugbe) and Mrs. T. Osho (nee Ojojo) joined the staff in 1921 and taught in the kindergarten classes attached to the school. Work progressed satisfactorily and later, the school was renamed Ondo Boys Public High School, and the Osemawe of Ondo appointed as its Proprietor. The Late Chief Sara Oladapo, a famous moslem leader, gave up his house at Alo Street to be used as classrooms. The late High Chief Sasere Ayodeji handed over his house to accommodate the Founder and (first) Principal, Rev. M. C. Adeyemi. The School first moved out of the Vicarage to an old Bookshop building at Oke-Otunba, where it spent only a term; and later settled at Alo Street until 1923, when it arrived at its present site, a 90-acre piece of land given by Oba Jisomosun II, the Osemawe, and Proprietor. The Osemawe also awarded the first scholarship of £20 (then N40) a year for three years, 1919-1922. Rev. Adeyemi gave his strength to the work of the School. The curriculum included Greek, Latin, Shorthand, Logic, etc. He introduced Scouting in 1920; established the OBHS Press in 1928 and suggested the formation of the Aionian Brotherhood of Secondary Schools in 1929. The school has passed through a long and unbroken period of successes. In September 1968, it became coeducational and comprehensive. Top civil servants, professionals and business men, University Dons, Diplomats, first class educationists, among them, Canon J. A. Iluyomade – Head of the International School, University of Ibadan – and Church Leaders are a few eminent Nigerians the School has produced.
