Èṣù is an Òrìṣà/Irúnmọlẹ̀ in the ìṣẹ̀ṣe religion of the Yoruba people. Èṣù is a prominent primordial Divinity (a delegated Irúnmọlẹ̀ sent by the Olódùmarè) who descended from Ìkọ̀lé Ọ̀run, and the Chief Enforcer of natural and divine laws - he is the Deity in charge of law enforcement and orderliness. As the religion has spread around the world, the name of this Orisha has varied in different locations, but the beliefs remain similar.
