The House of Cresius (Cresian pronunciation: [kɾesʲus]) was a political dynasty and later royal house that gathered prominence under Cresius I in the region of Cresia during the early 32000s DT. The family originated in the Cresian countryside, gradually rising until they controlled a Cresian tribe. From this power base, Cresius I gradually absorbed or conquered neighboring tribes, thereafter founding the Kingdom of Cresia.
