The struggle for the creation of Osun started as early as 1950. At that time, the present senatorial districts namely Osun West, Central and part of Osun East were subordinate towns under the administration of Ibadan District Native Authority but in there determination to get independence, traditional rulers and citizens of Osun Area submitted a petition to the British Colonial Administration in Nigeria demanding autonomy for Osun Division, with Osogbo proposed as the headquarters
To realise their aim, they pursued this agenda further in 1951, when a Commission Of Inquiry was set up the Colonialists, headed by H.L Butcher primarily saddled with investigating the crisis in Ibadan District Native Authority between Chief Salami Agbaje and Olubadan-in-Council. At this commission, named H.L Butcher Commission of Inquiry, a representation was made by people of Osun Area reiterating their resolve for autonomy. This demand was granted on March 17th 1951, thus recommending autonomy for Osun District Towns on April 1st 1951.
