Historically, the ltsekiri have a monarchy, over 500 years old, and which, as a rallying point in their society, remains its supreme government. From 1480 to now, there have reigned 19 Olu of Warri: five Olus of the pre-Christian era; 1480 - 1597: eight Roman Catholic Olus from 1597-1735, and six Olus of the post-Roman Catholic Christian era. Atuwatse I, baptized as Dom Domingo reigned between 1625 and 1643, having studied in Coimbra University in Portugal for eleven years where he obtained a degree. The first-ever church monastery built in what today is Nigeria was erected in Big Warri (Ode-ltsekiri) before 1700 and was christened Saint Anthony (today, the site is known as Satone).
