After the death of Eärendur, his three sons quarreled over the succession causing a civil war between them and their respective realms. Amlaith, the eldest son claimed the throne of Arnor but his rule was limited only to the region of Arthedain with its capital in Annúminas near Lake Evendim and then Fornost, while the others founded Cardolan and Rhudaur.
Its kings made several attempts to reunite the kingdom; Argeleb I was even able to exert its authority over Cardolan, but corruption in the kingdoms and war with Angmar prevented any reunification of Arnor. The kingdom and the title ended with the death of Arvedui but his line survived in the Rangers of the North, and being the senior kingdom of the Dunedain their chieftains formed the heirs of Isildur leading up to Aragorn Elessar.
