Long before the events of Game of Thrones or House of the Dragon, one man changed the history of Westeros forever.
Aegon Targaryen wasn’t born a king. He was a Dragonlord from Dragonstone who transformed seven independent kingdoms into one united realm through military strategy, diplomacy, and the overwhelming power of dragons. His conquest didn’t simply redraw a map—it created the Iron Throne and shaped the political landscape that would define Westeros for centuries.
From Valyria To Dragonstone
The Targaryens survived because they listened to prophecy.
Years before the Doom of Valyria destroyed the greatest civilization in the known world, Daenys Targaryen dreamed of the catastrophe and convinced her family to leave for Dragonstone. While rival Dragonlord families remained in Valyria, the Targaryens survived the Doom and became the last major Valyrian dragonriding family.
For almost two centuries they ruled Dragonstone, quietly growing stronger while Westeros remained divided.
The Dream That Started The Conquest

Aegon’s invasion wasn’t motivated only by ambition.
According to the history revealed in House of the Dragon, Aegon had prophetic dreams warning of a terrible threat from the North that could only be defeated if Westeros stood united under a single ruler. That belief later became part of the explanation for why Aegon sought to unite the Seven Kingdoms.
Rather than conquering purely for glory, Aegon believed a united Westeros would eventually be necessary for humanity’s survival.
Dragons Won Battles Before Armies Did
Aegon’s greatest advantage wasn’t simply having soldiers.
He possessed three dragons—Balerion, Vhagar, and Meraxes.
Among them, Balerion the Black Dread inspired unmatched fear. His enormous size and destructive power made him the ultimate symbol of Targaryen military strength.
Many rulers quickly realized they weren’t fighting an ordinary army. They were facing weapons unlike anything Westeros had ever seen.
Harrenhal And The Field Of Fire Changed Everything
Two battles convinced much of Westeros that resistance was becoming impossible.
King Harren believed the massive walls of Harrenhal could withstand any attack. Instead, Aegon flew Balerion directly above the fortress and unleashed dragonfire that destroyed the towers and killed Harren inside his own castle.
Soon afterward came the Field of Fire, where the combined armies of the Reach and the Westerlands attempted to overwhelm the Targaryens. The result became one of the bloodiest battles of the conquest as dragonfire devastated the opposing forces and permanently shifted the balance of power.
Those victories demonstrated that traditional armies alone could no longer guarantee victory against the Targaryens.
Why Torrhen Stark Chose To Kneel
One of the most famous moments of the conquest never became a battle.
Torrhen Stark marched south with the Northern army prepared for war. But after witnessing the destruction caused by the Targaryens and understanding the scale of Aegon’s forces, he chose another path.
Rather than sacrifice his people in a battle he believed he could not win, Torrhen bent the knee and became known as The King Who Knelt.
His decision preserved the North while recognizing Aegon’s authority.
A New Capital And A Lasting Legacy
After securing most of Westeros, Aegon established his seat of power near the location where he had first landed during the invasion. That settlement eventually developed into King’s Landing, which became the political heart of the Seven Kingdoms.
His greatest legacy wasn’t simply winning battles.
He created a united kingdom, forged the Iron Throne from the swords of defeated enemies, and founded a dynasty that would rule for nearly three centuries.
The political system created by Aegon became the foundation for the conflicts that followed. The civil war depicted in House of the Dragon and the struggle for the Iron Throne in Game of Thrones both take place in the world his conquest created.
Centuries later, his conquest remains one of the defining events in George R.R. Martin’s universe—not simply because one Dragonlord won a war, but because he permanently changed the political and historical fate of Westeros.
Although Aegon’s conquest united the Seven Kingdoms, the Targaryen dynasty would eventually tear itself apart during the Dance of the Dragons.
