Year ascended to the throne
- TA 2912
was the thirteenth of the Chieftains of the Dúnedain
Like his forefathers, he was raised by Elrond in Rivendell while his father Arathorn I dwelt in the wild. He became the Chieftain of the Dúnedain in TA 2848, when his father was killed by wolves.
During his rule, Gandalf entered Dol Guldur and discovered that it was Sauron who ruled there as he long had feared, and not the Witch-king of Angmar his servant. Thráin II the Dwarf died after giving Gandalf a map and a key.
The White Council met in TA 2850, where Gandalf urged an attack on Dol Guldur to drive Sauron out, but Saruman overruled him.
In TA 2890 Bilbo Baggins was born in the Shire, son of Bungo of the respectable Baggins family, and Beladonna, daughter of the Old Took.
At the end of Argonui's rule in TA 2911 the Fell Winter began and White Wolves invaded Eriador from the North, some of them crossing the frozen river Baranduin into the Shire.
Argonui died in TA 2912, possibly as a result of the Fell Winter, after sixty-four years and was followed by his son Arador.
