Full spoilers for all five seasons of The Last Kingdom and Seven Kings Must Die follow.

Short answer: The Last Kingdom begins around 866 and ends at the Battle of Brunanburh in 937, meaning Uhtred’s story covers roughly 70 years of English history. Season 1 takes us through Alfred’s victory at Edington in 878, Season 3 reaches Alfred’s death in 899, Season 5 moves into the final years of Edward’s reign, and Seven Kings Must Die carries the story into Æthelstan’s rule and the battle that helps secure a united England.

If that immediately makes you wonder why Uhtred appears to have aged approximately eleven years during seven decades of warfare, congratulations. You have discovered the single most important rule of The Last Kingdom timeline:

The history ages. Uhtred does not.

That makes the chronology confusing if you try to calculate the story from the characters’ faces, but the changing kings give us a much cleaner way to understand what is happening. The series begins in a Britain divided among competing kingdoms and ends with Æthelstan ruling something we can finally recognize as England.

That is the real timeline of The Last Kingdom: not simply Uhtred getting older, but a collection of kingdoms slowly becoming one country.

What Years Does The Last Kingdom Take Place?

The Last Kingdom begins in approximately 866, when the Great Heathen Army is attacking the Anglo-Saxon kingdoms and young Osbert loses the family and identity he was born into. He becomes Uhtred, is taken by the Danes and eventually grows up as part of Ragnar’s family.

The final chapter, Seven Kings Must Die, culminates in the Battle of Brunanburh in 937. That gives the entire screen story a historical span of roughly 71 years.

The important qualification is that The Last Kingdom does not maintain a perfectly literal calendar. Historical events are compressed, children sometimes appear younger than the dates require, older characters remain suspiciously youthful and some events are rearranged so the drama can keep its core ensemble together.

So the dates below are best understood as the historical framework around the story rather than proof that Uhtred is secretly using an excellent 10th-century moisturizer.

The Last Kingdom Timeline At A Glance

Season 1 Timeline: 866–878

Season 1 begins in 866, with Britain still divided into separate Anglo-Saxon kingdoms and Danish armies rapidly changing the political map. Young Osbert lives at Bebbanburg in Northumbria until the death of his older brother causes him to inherit the name Uhtred. His father is then killed fighting the Danes, and Uhtred is taken into Ragnar’s household.

The series jumps forward as Uhtred grows up among the Danes, but the larger historical movement continues around him. Northumbria and East Anglia fall under Scandinavian control while Wessex becomes increasingly important as the major surviving Anglo-Saxon kingdom capable of resisting further conquest.

By the time adult Uhtred reaches Alfred’s court, the story has placed its fictional protagonist directly inside one of the most important periods of Alfred’s reign.

878: Alfred, Athelney And The Battle Of Edington

The first season culminates around 878, one of the defining years of Alfred’s life. Guthrum’s forces attack Wessex, Alfred is driven into the marshes around Athelney and his kingdom appears dangerously close to collapse.

Alfred eventually rebuilds his army and defeats Guthrum at the Battle of Edington. Guthrum subsequently accepts baptism and a political settlement with Alfred, changing the balance between Wessex and Danish-controlled territory.

The major historical events are real. Uhtred’s decisive role in them is not, which becomes the basic storytelling method The Last Kingdom will use for the rest of its run: history provides the destination, and Uhtred gets inserted into the road that leads there.

If you want the larger breakdown of where that method is accurate and where the series starts moving pieces around, read How Historically Accurate Is The Last Kingdom? Where History Ends And Uhtred Begins.

Season 2 Timeline: Approximately 878–886

Season 2 begins almost immediately after the first season’s historical endpoint and sends Uhtred north. His story with Guthred, Kjartan, Ragnar, Thyra and Gisela is much more personal than Alfred’s political storyline, but the larger map continues changing underneath it.

Uhtred’s enslavement and rescue lead to one of the most important relationships in the entire series when he meets Finan. He eventually reunites with Ragnar, attacks Dunholm and settles into a life with Gisela before Alfred once again needs him.

The later portion of the season moves toward approximately 886, when Alfred historically secured control of London. The show connects that larger political movement to Æthelflæd’s marriage, the threat from Sigefrid and Erik and Uhtred’s continuing inability to stay out of Alfred’s business no matter how strongly he insists that he would very much like to.

Why 886 Matters To Alfred’s Dream Of England

London matters because Alfred’s story is becoming larger than merely preventing Wessex from being conquered. His political imagination increasingly points toward cooperation and authority across the remaining Anglo-Saxon territories.

This is also where The Last Kingdom begins quietly shifting its central historical question. Season 1 asks whether Wessex can survive. As the story progresses, survival becomes less interesting than what Alfred intends to do with that survival.

He wants England.

It does not exist yet, and Alfred will never personally rule the completed kingdom he imagines. But from this point onward, the series increasingly measures history against that dream.

Season 3 Timeline: Roughly 893–902

Season 3 has one of the messiest timelines because the show combines events that historically belong to several different years. Broadly, though, it takes place during the final years of Alfred’s reign and carries us through his death in 899 and the succession of Edward.

This is the season where the passage of time becomes harder to ignore because the political generation is visibly changing even if Uhtred still looks ready to headline a medieval cologne campaign. Alfred is dying, Edward is becoming an adult political figure and Æthelflæd has grown into someone capable of influencing Mercia’s future.

The story is moving away from the generation that began the project and toward the children who will have to complete it.

899: Alfred The Great Dies

Alfred’s death in 899 is arguably the most important transition in the entire series. David Dawson’s Alfred has been Uhtred’s principal political counterweight from the beginning, and their relationship gives the early seasons their central dramatic tension.

But Alfred’s death does not end his story because his real achievement is creating a project that can survive him. Edward inherits Wessex, Æthelflæd increasingly shapes Mercia and the idea of England becomes something the next generation is expected to continue.

That is why Uhtred’s final meeting with Alfred matters so much. Their relationship can end, but the work they have done together cannot. Uhtred will spend the rest of the series dealing with Alfred’s children, Alfred’s grandchildren and the consequences of the dream they both helped preserve.

How Old Is Uhtred Supposed To Be By Season 3?

This is where the calendar and Alexander Dreymon’s face begin openly disagreeing with each other.

If Uhtred is roughly twelve when the story begins around 866, he would be somewhere in his mid-forties by the time Alfred dies in 899. Depending on exactly how we interpret the show’s compressed chronology, the number moves around slightly, but the basic point remains the same: Uhtred is no longer supposed to be a young man.

The series simply chooses not to make aging a major visual concern. Dreymon changes subtly across the seasons, but nowhere near enough to match the historical years passing around him.

At some point, the healthiest way to watch The Last Kingdom is to accept that Uhtred exists in what I can only describe as extremely favorable warrior lighting.

Season 4 Timeline: Approximately 909–911

Season 4 is where attempts to build a perfectly consistent television timeline become especially difficult. The Battle of Tettenhall, one of the major historical anchors of the season, occurred in 910. Æthelred of Mercia died in 911, after which Æthelflæd became the Lady of the Mercians.

Those dates fit the political history the show is adapting, but they create problems with the apparent ages of several younger characters. Æthelstan, Stiorra and Ælfwynn do not always look as old as a literal reading of the calendar would require.

The best solution is not to force every character into an exact birth date. Treat Season 4 as roughly the period around 909–911 and understand that the adaptation is compressing family chronology to keep its cast and dramatic relationships manageable.

910: The Battle Of Tettenhall

The Battle of Tettenhall was a genuine major defeat for Scandinavian forces in England. In the show, it becomes another point where the interests of Wessex, Mercia, Wales and Uhtred’s own circle collide.

Historically, the battle helped weaken a major Danish army operating in the Midlands. Dramatically, it gives The Last Kingdom another opportunity to show the political landscape evolving beyond Alfred’s simple Wessex-versus-Danes framework.

The coalitions are becoming more complicated because the future England will not be created by one kingdom simply swallowing everything around it in a weekend.

911: Æthelflæd Becomes Lady Of The Mercians

After Æthelred’s death in 911, the real Æthelflæd ruled Mercia as the Lady of the Mercians. She would remain in power until her death in 918, working alongside her brother Edward while maintaining a remarkable degree of independent authority.

This is one of those places where the history itself gives The Last Kingdom an excellent character arc. Æthelflæd does not need the show to invent political significance for her. Her rise reflects the actual movement of power in Mercia.

The adaptation fictionalizes Uhtred’s involvement in that transition and their romantic relationship, but Æthelflæd’s emergence as one of the most important leaders of her generation is grounded firmly in history.

Season 5 Timeline: Approximately 917–920

Season 5 opens after another significant time jump. Uhtred has spent years at Rumcofa, Æthelstan has grown from a child into a young man and the next generation is now becoming capable of affecting the political story directly.

The clearest historical marker comes with Æthelflæd’s death, which occurred in 918. From there, the season uses a heavily fictionalized version of Edward’s northern politics, Sigtryggr’s rule and Uhtred’s eventual return to Bebbanburg.

By now, Alfred has been dead for almost two decades. That fact is easy to lose because Uhtred remains our visual constant, but it tells us how far the story has traveled. The man who once argued with Alfred as an irritating young warrior is now influencing Alfred’s grandson.

918: Æthelflæd Dies

Æthelflæd’s death in 918 provides another unmistakable chronological anchor. Historically, her daughter Ælfwynn briefly succeeded her before Edward brought Mercia under his direct authority.

The television version changes the circumstances and places Uhtred much closer to the political transition, but the overall historical movement is recognizable. The generation of Alfred’s children is beginning to disappear, while their territories move closer to political consolidation.

For Uhtred, Æthelflæd’s death is also another reminder of something the calendar has been telling us even when his face has not: he has lived a very long life and lost an extraordinary number of people along the way.

When Does Uhtred Finally Retake Bebbanburg?

Uhtred finally reclaims Bebbanburg at the end of Season 5, placing the television event somewhere around the early 920s within the show’s loose chronology.

This is important because Bebbanburg has been Uhtred’s external goal since the beginning. The political world has transformed enormously between the boy losing his home in 866 and the older Uhtred returning north to reclaim it.

When Uhtred finally reaches Bebbanburg, Alfred is long dead, Ragnar and Gisela are gone, Æthelflæd has died and the children who were once background pieces in the story are now becoming rulers themselves.

Uhtred gets the same home back, but he is no longer remotely the same person who lost it.

Seven Kings Must Die Timeline: Edward To Æthelstan

Seven Kings Must Die begins after Edward’s death in 924, creating a succession crisis that eventually places Æthelstan on the throne. Historically, Æthelstan first succeeded to Wessex and Mercia and by 927 had conquered York, allowing him to claim authority over a unified English kingdom.

The film then moves toward the Battle of Brunanburh in 937. That means a substantial amount of historical time is being compressed into a story that feels much more immediate on screen.

This is probably the most extreme example of the adaptation prioritizing dramatic continuity over literal chronology. If the movie visually communicated every year passing between Edward’s death and Brunanburh, Uhtred’s age would become impossible for the audience to ignore.

927: Æthelstan Becomes King Of England

Æthelstan’s importance is difficult to overstate. In 927, he took York and extended his authority across the major English territories, becoming the first ruler commonly recognized as king of a unified England.

That makes him the payoff to a political story The Last Kingdom has been telling since Alfred.

Alfred imagines England. Edward and Æthelflæd expand the territory and institutions capable of supporting it. Æthelstan finally inherits enough of that work to turn the idea into political reality.

Uhtred does not historically make this happen, of course, but dramatically he becomes the thread allowing us to watch three generations participate in the same unfinished project.

937: The Battle Of Brunanburh

The screen story ends around the Battle of Brunanburh in 937, where Æthelstan and his brother Edmund defeated a coalition that included Olaf Guthfrithson of Dublin, Constantine II of Scotland and forces associated with Strathclyde.

Brunanburh becomes the logical endpoint because it tests the kingdom Æthelstan has created. England is no longer merely Alfred’s theoretical dream. It is a political reality capable of facing a major coalition determined to break Æthelstan’s power.

The battle does not permanently solve every problem on the island, and historians continue debating aspects of its location and significance. But it becomes a powerful narrative endpoint for a series concerned with how England came into existence.

The story begins with kingdoms falling apart.

It ends with one kingdom managing to hold together.

How Old Is Uhtred At The End Of The Last Kingdom?

If we take the chronology literally, Uhtred would be somewhere in his early eighties by the Battle of Brunanburh in 937.

Yes.

Eighties.

That becomes even funnier when you remember exactly what Uhtred is doing during the final battle.

The series obviously does not portray him as an 80-year-old man. This is one of the clearest examples of the adaptation choosing emotional continuity over literal historical aging. Uhtred needs to remain a credible warrior because the story still requires him to function as one.

Trying to reconcile his appearance perfectly with the calendar will only make you angry at the concept of time itself.

Why The Last Kingdom’s Timeline Is So Confusing

The problem is not simply that the show makes mistakes. It is adapting a story that spans several generations while trying to preserve one central protagonist and a recognizable ensemble.

Real history does not care about television casting. Alfred can die. Edward can age. Children can become adults. Ten years can pass between major political events without worrying about whether the audience remembers a supporting character.

Serialized television has different needs. If The Last Kingdom aged everyone literally, Uhtred would change actors or spend the final seasons fighting from a comfortable chair while a succession of entirely new characters inherited the plot.

Instead, the show essentially runs two clocks. There is a historical clock, where kings die, children become rulers and documented battles happen decades apart, and there is a character clock, where Uhtred and several people around him age only as much as the story can comfortably absorb.

The clocks do not always agree.

Why The Timeline Still Works Dramatically

I am usually the first person to complain when a story asks us to ignore its own logic, but I think the timeline compression mostly works here because Uhtred is not actually the best measure of time in The Last Kingdom.

The kings are.

Watch the series through Alfred, Edward and Æthelstan and the chronology suddenly becomes much clearer. Alfred’s generation is trying to keep Wessex alive. Edward’s generation inherits that survival and pushes outward. Æthelstan’s generation finally inherits something large enough to call England.

That gives the series a beautiful three-generation structure even when the makeup department refuses to acknowledge the violence being done to Uhtred’s birth certificate.

Uhtred remains emotionally recognizable so the world around him can change.

The Real Timeline Is Uhtred’s Relationship With England

This is where the dates become more interesting than trivia.

At the beginning of The Last Kingdom, England does not exist and Uhtred has very little reason to want it to exist. Alfred’s dream is somebody else’s obsession, and Uhtred is much more concerned with reclaiming Bebbanburg than participating in a grand national project.

Then decades pass.

He fights for Alfred. He loves Alfred’s daughter. He protects Alfred’s son. He helps raise and protect Alfred’s grandson. He watches Saxons and Danes become increasingly difficult to separate into the neat categories that defined his childhood.

By the time Æthelstan can plausibly call himself King of England, Uhtred has spent most of his life helping create the thing he once insisted had nothing to do with him.

That is why the long timeline matters.

England doesn’t simply appear because Alfred gives a good speech about it. The dream outlives Alfred, passes through his children and finally becomes real under his grandson.

Uhtred’s Life And England’s Life Are Opposite Stories

There is another piece of the structure I really love. Uhtred begins the series with a clear identity and loses it. England begins the series with no unified identity and slowly gains one.

Young Uhtred knows exactly who he is supposed to be: the son and heir of Bebbanburg. Then the Danes take him, Ragnar raises him and every simple category becomes complicated. Saxon and Dane, pagan and Christian, Northumbrian and servant of Wessex all begin competing inside one person.

England travels in the opposite direction. Wessex, Mercia, Northumbria and Danish-controlled territories begin as competing political identities and are slowly forced into a larger structure.

So across roughly seven decades, Uhtred becomes more complicated while England becomes more unified.

That is not an accident. It is the dramatic architecture underneath the historical timeline.

The Last Kingdom Timeline Isn’t Really About Dates

The dates are useful because they help us understand just how enormous the journey actually is. Roughly 71 years separate the beginning of Uhtred’s story from Brunanburh, even if the television production cannot possibly make every one of those years visible.

But the dates are not what makes the timeline meaningful.

What matters is succession.

Alfred cannot finish the work. Edward cannot finish it either. Æthelflæd contributes another crucial piece before dying. Æthelstan inherits a project that began before he was born and finally pushes it across a threshold his grandfather never got to see.

Meanwhile Uhtred, the fictional man who supposedly wants nothing to do with anybody’s kingdom, somehow remains standing beside all of them.

He is the continuity device that makes generations of history feel like one story.

So, What Is The Last Kingdom Timeline?

The Last Kingdom begins around 866 and concludes around 937, covering roughly seven decades of Anglo-Saxon and Viking history. Season 1 takes us through Alfred’s victory at Edington in 878. Season 2 moves toward 886. Season 3 carries the story through Alfred’s death in 899. Season 4 draws heavily on events around 909–911, while Season 5 reaches the period around Æthelflæd’s death in 918 and Uhtred’s eventual recovery of Bebbanburg.

Seven Kings Must Die begins after Edward’s death in 924 and compresses the following years before culminating at Brunanburh in 937.

The chronology is not perfectly consistent, particularly when it comes to the characters’ ages. But if you stop using Uhtred’s face as a calendar and watch the changing generations of rulers instead, the entire structure becomes much easier to see.

Alfred dreams of England.

Edward and Æthelflæd build more of it.

Æthelstan finally rules it.

And Uhtred spends roughly 70 years insisting that none of this is his problem while somehow being involved in almost every part of it.

Destiny is all. Apparently aging is optional.
