Adat Yang Diadatkan emerged as a result of a consensus between adat elders and Orang-Orang Besar of Serdang Sultanate in East Sumatra (now North Sumatra) during the administration of Sultan Ainan Johan Alamsyah (1767 – 1817), the second Sultan of Serdang. This custom becomes one of Sultan Ainan Johan Alamsyah policies to stricter the laws on custom and tradition applicable in Serdang Sultanate territory.
