By the time Argeleb came to power, the line of kings had failed in the kingdoms of Cardolan and Rhudaur, so Argeleb claimed sovereignty over all of Arnor (taking the royal prefix ar(a)- as a token of this). He was thus not only the seventh King of Arthedain, but also the seventeenth King of Arnor.
Cardolan accepted this rule, but by then Rhudaur had fallen under the control of Angmar, and resisted his rule. It was about this time that the remaining Stoors in the Angle left the area due to hostile nature of Rhudaur to either return to Wilderland or to go westwards like other hobbits. Argeleb fortified the hills at Weathertop, and was killed in 1356 T.A. by evil men from Rhudaur.
Argeleb ruled for only seven years, and was succeeded by his son, Arveleg I, upon his death in 1356.
