10 Greatest Kings in Game of Thrones History

Westeros has been ruled by conquerors, reformers, and rulers whose decisions rippled for generations. Here are 10 of the greatest kings in Game of Thrones history—ranked by what they achieved, and by how their choices helped (or hurt) the realm.

The Iron Throne has always been less about ceremony and more about consequences. In Westeros, a king’s legacy isn’t just measured by the wars he survives—it’s measured by the peace he keeps, the reforms he pushes through, and the fractures he leaves behind.

Across the Age of Heroes. the rise of the Seven Kingdoms. and the aftermath of unification. some rulers managed to hold the realm together. Others brought order for a while—then watched it unravel under the weight of their own decisions. Here are 10 of the best kings in Game of Thrones history, ranked.

10 Robert I Baratheon

Robert I Baratheon (Mark Addy) didn’t just rise to power—he tore it out of the Targaryens. After defeating Rhaegar Targaryen (Wilf Scolding) in single combat and earning the nickname “The Demon of the Trident,” he took the Iron Throne and ruled for 15 years.

He had the kind of presence that reads as effortless on the battlefield and in the court—charismatic. larger than life. and well-liked by both soldiers and nobles. But Robert wasn’t consistent about what the crown demanded. He enjoyed the luxuries of being king while letting much of the governing fall to his council. spending his time hunting and drinking instead.

That hedonism didn’t stay contained to his personal life. The realm fell deeply into debt, and the debt helped push his reign toward its downfall.

9 Baelor I Targaryen

Baelor I Targaryen wasn’t the kind of king who leaned on conquest. With enemies striking from all sides, peace is rarely a monarch’s first instinct—but Baelor made it his defining agenda.

Inspired by his devotion to the Faith of the Seven, Baelor was responsible for ending the conflict started by Daeron I and eventually securing a peace agreement with the Dornish.

Yet his sacred beliefs and charitable nature spiraled into blind spiritual fanaticism. His governance, once rooted in ending war, became less about strategy and more about religious zealotry. Many of his “great ideas” came from visions he claimed to receive—leading to questionable decisions that included expelling thousands from King’s Landing and attempting to replace ravens with doves.

8 Daeron I Targaryen

Daeron I Targaryen ascended the Iron Throne at just fourteen years old, making him one of the youngest rulers in Westerosi history. Youth brought him remarkable courage, and he responded by launching a military campaign to conquer Dorne despite lacking dragons.

Unlike the Targaryens who came before him, Daeron initially achieved his goal. He could win the kind of battles that looked impossible when measured against dragons and experience.

But holding Dorne required years of experience and maturity—something he simply didn’t have yet. Daeron may have won battles, but he had not won the war. He died young before he could grow into a more seasoned leader.

7 Viserys I Targaryen

Viserys I Targaryen (Paddy Considine) inherited a kingdom that was already prosperous. That meant he began his reign during one of the wealthiest and most peaceful periods in Westerosi history.

Over 26 years, Viserys maintained a diplomatically stable realm with minimal disruptions. He stayed popular with both nobles and commoners.

The problem arrived at the center of every throne’s long-term stability: succession. Throughout his life, Viserys was well-liked, and his reluctance to make difficult or unpopular decisions kept him from confronting growing tensions.

When he failed to ease the tensions between Rhaenyra (Milly Alcock) and Aegon II Targaryen (Tom Glynn-Carney), his indecision helped set the stage for the Dance of the Dragons.

6 Maekar I Targaryen

Maekar I Targaryen (Sam Spruell) was known as “The Anvil” for good reason. He was renowned for defeating the Blackfyre rebels, and he never expected to become king.

But desperate times arrived—marked by the deaths of multiple heirs—and his record in the field became a necessity rather than a resume. Maekar was entrusted with protecting the realm.

Still, battle skill doesn’t automatically translate to political finesse. Because of his background, Maekar lacked charisma and the ease of winning over his council and subjects. He wasn’t cruel, though—he was known to fight alongside his men. That trait helped define him, and it also contributed to his death.

5 Aegon V Targaryen

Aegon V Targaryen (Dexter Sol Ansell), affectionately known as “Egg” in his youth, is the kind of king the realm least expects to find. As a child, he spent much of his time traveling, and those experiences gave him a firsthand view of the hardships faced by common people.

When he ascended the throne, he set out to improve their lives. He enacted laws aimed at protecting the smallfolk.

But not every reform lands cleanly. Aegon’s idealism—well-intentioned as it was—wasn’t always welcomed by the nobility. many of whom preferred preserving the traditional social order. Without dragons to enforce his agenda. Aegon later became obsessed with restoring them. convinced that dragons would give him the authority to compel nobles to accept his reforms.

4 Viserys II Targaryen

Viserys II Targaryen’s reign lasted barely a year, but he’s still considered one of the most capable administrators in Targaryen history. After the Dance of the Dragons, Viserys’ pragmatic approach helped rebuild royal authority.

He served as the pillar that kept the kingdom running during the troubled reigns of Aegon III, Daeron I, and Baelor I.

What Viserys lacked was warmth. He preferred objective and practical approaches and was willing to make difficult and even controversial decisions if they promised stability. The problem was simple: his short time as king didn’t give him the chance to fully flesh out his potential.

3 Aegon I Targaryen

Aegon I Targaryen is the hinge point in Westerosi history. Without him, there would be no Iron Throne, no unified Seven Kingdoms, and no Targaryen dynasty.

He ended centuries of division among the kingdoms—even if it required considerable force. For all his ruthlessness, he made unification easier to maintain by allowing defeated lords to keep their lands and customs if they chose to surrender.

Aegon’s success, though, leaned heavily on overwhelming military superiority, especially through dragons such as Balerion, Vhagar, and Meraxes. With dragonpower at the center, few could realistically challenge him.

His reign also left behind succession issues, and the reigns of his sons only contributed to further instability within the monarchy.

2 Daeron II Targaryen

Daeron II Targaryen had to prove something beyond lineage. It takes integrity and goodwill to distance yourself from a corrupt father—especially when that father is Aegon IV—and Daeron II did forge his own path.

Scholarly and diplomatic, Daeron II brought Dorne into the Seven Kingdoms through marriage and negotiation rather than threats and intimidation.

But he couldn’t escape the long shadow of his father’s decisions. The First Blackfyre Rebellion, stemming largely from Aegon IV’s actions, became one of Daeron II’s hardest legacies to manage. Even after defeating Daemon Blackfyre, Daeron II struggled to win over the surviving Blackfyre supporters.

1 Jaehaerys I Targaryen

Jaehaerys I Targaryen (Michael Carter) is widely regarded as the greatest king to sit on the Iron Throne. He ruled for 55 years and ushered in an era of prosperity.

His reign strengthened the realm on multiple fronts, including ending hostilities between House Targaryen and the Faith of the Seven, and helping unify the kingdom’s legal system. His most renowned strength was his ability to resolve disputes without immediately relying on dragons or military force.

Still, even greatness didn’t protect him from the beliefs of his era. As the Old King, Jaehaerys was raised within a deeply patriarchal society, and he has been criticized for his approach to succession. He appeared to favor male heirs over female claimants.

His old-fashioned thinking also affected his own family matters, especially his relationship with his daughters.

The decisions that define a king in Westeros rarely stay contained. Robert I Baratheon’s courtly charm and personal indulgence helped drag the realm into deep debt. Baelor I Targaryen’s peacekeeping vision became zealotry driven by claimed visions. from expelling thousands from King’s Landing to trying to replace ravens with doves. Viserys I Targaryen maintained a stable realm for 26 years—until succession tensions he wouldn’t confront helped ignite the Dance of the Dragons.

Those aren’t just character traits. They’re the human gravity of a throne: the same kingdom that can flourish under steady administration can also crack when a ruler hesitates, fixates, or rules without the political balance power demands.

And that’s the shape of the rankings—because in Westeros, greatness isn’t only what you accomplish. It’s what you prevent from breaking the realm while you’re gone.
