The Oath Wars were a large conflict between the clergies of Nethys, Norgorber, and Sarenrae in order to decide which among them would become the dominant religion in northwestern Garund. The battles began in 2498 AR, when the newly embraced religion of Sarenrae spreading into the region, coming into conflict with the already established religions of Nethys and Norgorber. Once it began, it became an all-out war between the zealots of the three religions.
This large conflict devastated the entire region and likely would have continued, had not the city of Azir exiled all clergy from its territory. Led by the philosopher Kalim Onaku, the city created the Laws of Man, the first of which barred the worship of any deity. The Laws spread throughout the region, causing the total eviction of all religiously-minded people on pain of death. Thus emptied of its original instigators, the Oath Wars ended in 2560 AR and the country of Rahadoum was founded.
