Arahad I was the seventh of the Chieftains of the Dúnedain.
He became the Chieftain of the Dúnedain in 2455 at the death of his father. During his rule it was confirmed that Sauron had returned to Dol Guldur, and the Watchful Peace came to an end. In Rivendell the White Council was formed, of which he became a member, together with the Wizards and many Elf-lords.
Arahad died in 2523, and was followed by his son Aragost.
