of Arthedain > Argeleb I
Argeleb was a dunadan and the seventh King of
Arthedain. Since no
heirs of Isildur remained in either Rhudaur or Cardolan, Argeleb sought
to reunify the Kingdom of Arnor.
Soon he started to fortify the Weather Hills, but
the war with Angmar
began, and Argeleb was slain in battle.
