The Fall of Arnor & Saruman's Betrayal: LOTR Third Age Explained
The Third Age: Sauron's Return, the Istari's Arrival, and the History That Defined The Lord of the Rings
You've seen the battles, you know the Fellowship. But Frodo's quest is merely the final chapter of a 3,000-year-long story. Have you ever wondered who Aragorn *really* is, or why Gandalf, a being of immense power, often seems so restrained? The answers lie buried in the deep, complex history of the Third Age.
The cinematic epics from Peter Jackson masterfully capture the War of the Ring. However, the true weight of that conflict—the ancient prophecies, the broken bloodlines, and the millennia-old schemes—is rooted in events that transpired long before Bilbo ever found the Ring. This history, drawn from J.R.R. Tolkien's vast legendarium, provides the critical context that transforms The Lord of the Rings from a simple fantasy adventure into a profound modern myth.
In this article, we will delve into that foundational history. We'll uncover the tragic loss of the One Ring, the secretive return of Sauron, the arrival of the mysterious Wizards (Istari), and the seeds of Saruman's betrayal. This is the story of the Third Age, and understanding it is the key to understanding the entire world of Middle-earth.

The Shadow of Isildur's Folly: A King's Death, a Kingdom's End 🤔
The Disaster of the Gladden Fields
The Third Age began with a victory that felt like a defeat. After cutting the One Ring from Sauron's hand, Isildur, the new High King of Gondor and Arnor, had a choice. Elrond and Círdan implored him to destroy the Ring in the fires of Mount Doom. He refused. Claiming it as "weregild" for the deaths of his father and brother, Isildur kept the Ring, sealing his own doom and ensuring that the shadow would one day return.
Just two years into the Third Age, Isildur was marching north to his kingdom of Arnor. His party was ambushed by a massive host of Orcs in the valley of the Anduin, an event known as the Disaster of the Gladden Fields. The Ring, possessing its own will, betrayed him. It slipped from his finger as he tried to escape in the great river. Visible again, Isildur was shot down by Orc arrows, and the One Ring was lost in the murky riverbed for over 2,400 years.
The Sundered Kingdom: Arnor's Fall and the Birth of the Rangers
Isildur's death left the legacy of Númenor fractured. His southern kingdom, Gondor, endured, but his northern kingdom, Arnor, faced a darker fate. Arnor itself splintered into three smaller, rival realms: Arthedain, Cardolan, and Rhudaur.
This division proved fatal. Around T.A. 1300, Sauron's chief lieutenant, the Lord of the Nazgûl, traveled north and established the evil kingdom of Angmar. His title, the Witch-king of Angmar, would become a name of terror. For centuries, he waged a relentless war against the divided northern kingdoms, eventually destroying all three. The last remnants of Isildur's royal line in the north were driven into the wild.
They did not vanish. They became the Dúnedain, or the Rangers of the North—a grim, secretive people who guarded the lands of Eriador (like the Shire) from the shadows, never revealing their true heritage. Aragorn, son of Arathorn, was the last chieftain of this broken line, the true heir of Isildur, fighting for a people who didn't even know he existed.
A New Hope: The Arrival of the Istari (Wizards) 🧙♂️
Who Were the Wizards? Emissaries from Valinor
Around the year T.A. 1000, as the first shadow of a returning evil began to stir, the Valar (the divine "Powers" of the world, akin to archangels) decided to intervene, but not directly. They sent five emissaries from their own order, the Maiar (lesser divine spirits), to Middle-earth.
These were the Istari, whom Men called Wizards. They were forbidden from matching Sauron's power with their own or ruling the minds of Elves and Men. Instead, their mission was to advise, guide, and inspire the free peoples to find their own strength. To ensure this, they were clad in the bodies of old, frail-looking men, subject to the pains, fears, and weariness of mortals.
The Five Emissaries and Their Missions
While five Istari arrived, Tolkien's main narrative focuses on three:
- Saruman the White: The leader of the order. He was proud, powerful, and a master of craft and voice. He was chosen to lead the White Council.
- Gandalf the Grey: Known in Valinor as Olórin, he was the wisest of the Maiar but was humble and initially afraid of the mission. He was convinced to go, and upon his arrival, Círdan the Shipwright secretly gave him Narya, the Elven Ring of Fire, to aid him in "rekindling hearts" in a world growing cold.
- Radagast the Brown: A gentle spirit chosen by the Vala Yavanna, he became enamored with the beasts and birds of Middle-earth, largely forgetting his greater mission to focus on the natural world.
The other two, the Blue Wizards (Alatar and Pallando), traveled far into the east of Middle-earth on a mission to stir up rebellion against Sauron's influence there. They never returned, and their fate remains one of Tolkien's great mysteries.

The Necromancer of Dol Guldur
Around the same time the Istari arrived (T.A. 1050), a new, dark shadow fell upon the Greenwood, which was soon renamed Mirkwood. A fortress was built at its southern end, called Dol Guldur. The Wise, including Elrond and Gandalf, believed this shadow was one of the Nazgûl.
They were wrong. The power grew, and evil things multiplied. This mysterious entity was known only as the Necromancer. For centuries, this power consolidated, spreading plague and war.
It was Gandalf who first suspected the truth. In T.A. 2850 (less than 100 years before *The Hobbit*), he dared to infiltrate Dol Guldur. There, in the deepest pit, he found the dying Thráin, Dáin's father, and confirmed his worst fear: the Necromancer was not a Ringwraith. It was Sauron himself, regaining form and actively searching for the One Ring.

The White Council's Fateful Delay
Armed with this terrible knowledge, Gandalf rushed to the White Council—a group of the Wise led by Saruman and including Elrond, Galadriel, and Círdan. Gandalf urged an immediate, all-out assault on Dol Guldur.
Saruman overruled him.
Saruman, the council's leader, counseled patience. He argued that Sauron could not regain his full strength without the Ring, and that the Ring was, as he claimed, "lost forever in the Sea." This was a lie. Saruman, through his own deep study, had become obsessed with the Rings of Power. He had secretly begun using the Palantír of Orthanc, a seeing-stone, and had been corrupted by Sauron through it.
Saruman's true motive was chilling: he wanted the One Ring for himself. He allowed Sauron to remain in Dol Guldur, hoping the Dark Lord's growing power would "draw out" the Ring, revealing its location so Saruman could seize it first. His betrayal cost the Free Peoples decades, allowing Sauron to complete his plans and return to Mordor in secret.
Why This 3,000-Year-Old History Matters 📚
This ancient history isn't just trivia; it's the engine of the entire plot of The Lord of the Rings. Understanding it deepens the story immeasurably.
- Aragorn's True Weight: He isn't just a tough Ranger. He is the last heir of a 3,000-year-old broken royal line, carrying the shame of Isildur's failure and the duty to restore a kingdom lost to history.
- Gandalf's True Purpose: His power isn't throwing fireballs (though he can). His limitations are *by design*. His true mission, aided by the Ring of Fire, is to inspire hope and courage in others, not to win their battles for them.
- Saruman's Tragic Fall: His betrayal is the ultimate cautionary tale. He believed he could study and understand evil without being corrupted by it. His arrogance—his belief that he was wise enough to control the Ring—was his downfall, proving that wisdom and power are not the same.
The War of the Ring was not an isolated event. It was the climax of a long, desperate struggle defined by a king's failure, a wizard's humility, and a wise man's betrayal. The Third Age set the stage, and all it needed was the smallest of people—a Hobbit from the Shire—to finally bring the curtain down.
