The Ìjẹ̀bú-Imuṣin community was formed by one of the earliest groups of people to move out of the acclaimed cradle of Yorùbá civilization, Ilé-Ifẹ̀, ca: 2nd century CE.
The Imuṣin group was led by Ọ̀ṣífadérìn, he first Olókò and founder of the Òkò kingdom built around a community whose main quarters exists till today as Ìdokò Ọlọ́wá, Ìdokò Àjàṣẹ́, Ìdokò Ṣùbúgbàwá, and Ìdokò Alẹdò. Legends report that the Ọbańta group that came out of Ilé-Ifẹ̀ and established the Awùjalẹ̀ line of rulers and enlarged the reach of Ìjẹ̀bú-Òde, the principal city of the Ìjẹ̀bú, were welcomed and helped with directions by Òdútẹ̀, the second Olókò.
While Olókò was hosting Ọbańta—and future Awùjalẹ̀—at Òkò’s central market, Ọbańta’s son died. He stuck on his son’s gravesite a walking cane carved out of an iṣin (ackee: blighia sapida) tree limb. From the mighty tree that sprouted on the spot, and grows still at the center of the market, the community created the permanent name Imuṣin.
Many communities, from both the original Ọ̀ṣífadérìn contingent, other migrant groups from nearby settlements, including Ìjẹ̀bú-Òde, found solace around Ìdokò and formed the multitude of communities, estimated to be as many as 480 at some point in history, that developed around Imuṣin. The historic Imuṣin cluster teemed with great leaders, among whom the most historically prominent are Máagúnṣẹ̀n at Ìtamárùnún, Obelu at Èṣuré, Nọ́pà at Òdonọ́pà, Ògirimàdàgbó at Ìlódò, and Oyèbọ́lá at Ìgbàgà.
Today, Imuṣin is a vibrant, small sized city, at the center of which the marketplace sits majestically. Within every kilometer, one would run into an elementary school. The community is adorned by architecturally remarkable private homes, churches, and mosques. Imuṣin is served by an eye hospital, banks, and a community health center. The city boasts of several secondary schools, a magnificent e-library, restaurants, and hotels.
