Ogiso is the name used by the people of Igodomigodo or (Ugodomigodo) to refer to the institution and first dynasty of rulers beginning approximately around 900–950 AD or the mid tenth century. The name variously translates to mean 'King from the sky', 'King of the sky', or 'King of heaven'. Broken down, the word is coined from the article pieces -Ogie; the Edo word for king, and -Iso; the Edo word for sky. Early traditions narrate that these early kings (Ogie) descended from heaven. The first of them, Igodo, is believed to have been a stranger from the sky because of his immense wisdom. Not much is known about the reign of the Ogisos compared to the era of the Obas, and the period is often said to be of a semi-mythical or legendary nature.
