Arathorn I was the twelfth Chieftain of the Dúnedain.
Like his forefathers, he was raised by Elrond in Rivendell while his father Arassuil dwelt in the wild. Arathorn became the Chieftain of the Dúnedain in TA 2784 at the death of his father. His rule was largely an uneventful one, as the Dúnedain and other peoples of Eriador were recovering from the Long Winter.
At the southern fringes of his realm, great events occurred: the Dwarven King Thrór was slain by Azog, an Orc of Moria. From TA 2793 – TA 2799 the War of the Dwarves and Orcs was fought all through the Misty Mountains, as Dwarves from all Seven Houses gathered to avenge Thrór, the Heir of Durin.
After the War ended in 2799 at the Battle of Azanulbizar, Eriador was safe from Orcs for many years, which meant that the Rangers of the North had a relatively safe period, aside from fighting the occasional Orc refugee. Most Orcs fled south to Rohan, trying to settle the White Mountains. Arathorn died in TA 2848 when he was attacked by Wolves, and he was followed by his son Argonui. He served as chieftain for sixty-five years.
