-What sets this burial apart is that it doesn't just have weapons, it has all the weapons.
-These weapons could only have belonged to a mighty warrior.
The modern-day image of a Viking is a big, strong, bearded man, fearless and capable of the worst atrocities.
He sailed the rivers and oceans in search of treasure and glory -- the scourge of the North.
-All the clichés of rape and pillage are not just clichés.
-This grave and its contents have only fueled these clichés.
But in the 1970s, a young osteo-archeologist put forward a startling hypothesis -- the skeleton wasn't that of a man, but a woman.
Now a team of experts is determined to find out who was buried in the grave.
-Horses, weapons, shields -- everything you need to be a professional warrior -- and we now know that this warrior was actually a woman.

He knows the presence of horses in a Viking grave suggests it belongs to an important person.
For several days, the team attempts to reach what is hidden under the stone.
Finally, they are forced to dynamite the boulder.
This grave is numbered Bj 581 -- Bj for Bjorko, and 581 because it is the 581st grave unearthed by the archeologist.

Bj 581 contains a stockpile of medieval weapons -- shield, knife, bow and arrow, spear, axe, and sword -- a strong suggestion the grave belonged to a great warrior.
-We would think that, "Well, the Viking Age, there must be weapons in lots of graves," but there are not, actually.

They created trade routes to the East, reaching Baghdad via the Caspian Sea and Constantinople via the Black Sea.
In these territories, where many settled, they were often called the Rus', or "redheads."
Further south, they colonized England, led raids in France, and even sailed up the Seine to Paris several times.
They bypassed the Iberian Peninsula, attacking and looting in the Mediterranean from North Africa to Italy.
Vikings were also known for their quests of exploration.
After Scotland and Ireland, they colonized Iceland, then Greenland, and finally landed in America five centuries before Christopher Columbus.
Whether calling themselves Danes, Normans, or Rus', Vikings settled all over Europe and mixed with the local people.
Though they played a key role in world history, not a great deal is known about their culture.

She is responsible for cataloging the contents of many graves, including those of Bj 581.
-The task of doing an inventory of all the skeletons from Birka, grave by grave.
It's just checking what's in the archive.
-Using Stolpe's sketches, Vilkans rebuilds each skeleton as she logs the bones.
In all, Vilkans analyzes 101 graves that contained 117 people.
She has performed the job of a forensic pathologist and creates a 75-page report listing bones, recording their condition and size, age at death, and numerous other details.

Stolpe's team only found 40 of this human's 206 bones.
But analysis of the remaining bones can give a clearer picture of the individual's height.
-The skeleton is very tall.
It's a long person.
It's somebody who's over 1 meter, 70 centimeters.
-Several human bones can be used to determine a person's size.
Generally, the longest leg bone, the femur, is key to estimating how tall a person is.
♪♪ But in the case of Bj 581, both femurs are incomplete.
Instead, Vilkans relies on the tibias, which are in better condition.
The results suggest a person of average height for the time.
-Bj 581 was about 170 centimeters, based on estimations from the tibia, the only completely preserved long bone.
-The average height for a Scandinavian man then was 5'6", or 167 centimeters.
Contrary to Medieval beliefs, Vikings were not giants.
A woman's height rarely exceeded 5'2".
Based on height, the skeleton of grave Bj 581 seems male.
But another detail attracts Vilkans' attention.
The bones of the forearms are thin and slender, typical of a woman.
-Based on the size, this is from a man, and this is from a woman.
But there are large and tall women, and there are also small and tiny men.
-Using her skills as an osteo-archaeologist, Vilkans then looks at the remaining pelvic bone, the left hip.
Although broken into several pieces, it still proves helpful.
♪♪ Childbirth requires women to have different pelvic bones than men, and they are often used to determine gender.
The pubic arch, for example, is much larger in women.
Above that, the ilium is narrower in men.
And finally, the pelvic inlet is wider in women.
-The inlet of the pelvis is larger and more circular in females than in males.
And this is, of course, because there is a baby coming out here.
-For the young researcher, no doubt remains -- the skeleton of one of the most famous Viking warriors, discovered a century ago, is not that of a man, but a woman.
-She made a note when she went through the material that this was probably a female.
-However, the bone is damaged, and the pubis is missing.
The upper part of the skull of the skeleton in Bj 581 could confirm the gender.
Skull bones have certain characteristics that are gender-specific.
-The margins of the orbital is more rounded in males.
And then we have muscle attachments behind the ears and on the occipital bone, which are more pronounced in males, as well.
-Though Stolpe's drawings include the skull, it has since gone missing.
The skull from the most famous Viking grave can't be found.
-So, this material was excavated more than 100 years ago.
During the late 19th century, they also had a tendency to separate the cranium from the post-cranial bones and put in a separate box.
And they have been repacked and put in different boxes, and so on.

We think it's out there somewhere.
-It's possible that it is still in the collection.
But, still, of course, it is a problem.

When I looked at the innominate bone, it had all the female features, so this is why I think it was a female.
-She announced this at a seminar, and there were two reactions in the room.
One of them was me, 'cause I sat there and said, "Wow!"
really loudly, and the other was a colleague at the back of the room who said, "But that can't be!"

[ Men shouting ] The analysis of the bones buried for centuries isn't enough to change minds.
And new questions about the analysis quickly emerge.
-There was a rumor that all the graves were mixed up and it was impossible to use the skeletal material.
-The skeptics had not considered the high standards that Stolpe set for his dig.
Stolpe begins his career as an entomologist, arriving on the island of Bjorko in 1871.
Farmers and cattle occupied the island then.
-He's hoping to find remains of prehistoric insects fossilized in amber, and it's when he goes to the island and sees these thousands of burial mounds, sees the remains of this Viking town, that he begins to change his ideas.

-Stolpe returns to Birka every summer and fall for the next 10 years for the extensive excavations.
His team uncovers close to 1,100 graves, and each is excavated with a rigor and precision that is unprecedented for its time.
Stolpe meticulously documents each bone and item found in every grave.
Today, researchers still rely on his notes.
-Hjalmar Stolpe is one of the founding fathers of Swedish field archeology.
-What sets Stolpe apart from his contemporaries is the kind of scientific rigor, his carefulness that he brings to this.
-So, he used millimeter paper.
He used rulers and technical equipment.
-He was so very, very careful in the way he recorded what he found.
-To me, he's this great scientist because he left everything in order, making it possible for us, more than 100 years later, to go back to his excavations, trust what he did, and do something new.
We can have a new interpretation based on his excellent ground work.
He was a pioneer in that sense.
-Stolpe's detailed catalog will be key to determining who was buried in grave Bj 581.
He ensured there would be no confusion about which grave each bone came from.
All of the skeletal remains have been marked with India ink.

-The soil in Birka is not very good for preservation of skeletons, so many of these inhumation burials actually lack skeletons.
There can be a tooth or just one bone preserved, and the rest has deteriorated.
-150 years ago, Stolpe noted many graves did not contain any bones.
-They're not very well-preserved.
Lots of the information is actually missing.
-Fortunately, this is not the case for Bj 581.
-This is a very well-preserved skeleton for Birka, and it has a complete spine, it has all the features making it possible to estimate height and sex and age and so on.
-The grave's location explains why the skeleton was so well-preserved.
Because the grave was built on a slight slope, rainwater moved away from of it instead of seeping inside and damaging the bones.
While the bones themselves are in relatively good condition, the same is not true for their genetic material, much of which has been destroyed over time.
After all, the bones did spend 1,000 years buried in dirt, where millions of microorganisms flourished.
The first task is to separate the human skeletal DNA from everything else in the soil.

During this era in Scandinavia, people lived in rural villages and survived by farming, hunting, and fishing.
-It's a society that is divided up into small communities -- family-based, rural societies.
-The society is patriarchal, but women here enjoy more freedom than women in Christian Europe.
They can inherit property, divorce, and sometimes even choose their own husbands.
Clans exercise local authority.

They're never common, but they do exist.
If you look at 581, it's very clear.
Stolpe writes explicitly that this is the only body in the grave.
There is nothing in his documentation to suggest otherwise.
If we look at the objects in the burial, they're all grouped around the skeleton that we have.
There are no other bones labeled as being from the grave.
We've even DNA tested the different parts of the skeleton, and it's from the same individual.
There's no doubt at all that she was alone in the burial.
-A woman was buried in Bj 581, and she was buried alone.
But the grave is remarkable for other reasons.
-The biological sex of the skeleton was not our only question.
Be it man or woman, it's a super interesting grave.
-The grave caused a sensation when it was discovered in 1878 because it contained so many weapons.
-Finding weapons is not that unusual in Viking archaeology.
We find them sometimes in graves, we find them on settlements.
We know that they were a very common part of the material world.
What sets this burial apart is that it doesn't just have weapons, it has all the weapons.

-The spear is the weapon of choice of the god Odin, who is the god of war.
These are not for throwing.
These are for close-quarter fighting.
It's a weapon for the battlefield.
-Spears were also less expensive to produce, which meant warriors could afford to equip themselves fully.
♪♪ It's possible the weapons were simply decorative, never taken to battle.
But analysis shows a trained warrior used them.
They were not ceremonial.
A swordsman, or woman, was much respected in Viking communities.
-The sword has its position because it being expensive and connected to people with wealth and influence, but also because it's a uniquely efficient personal weapon.
So, owning a sword was also making a point that you belonged to an elite in society.
In the grave of Bj 581, we have a sword.

Some are marked with a large rock, like a gravestone.
-Sometimes they put up stones on top of the graves, and when they're bowder stones like this, that indicates that it was a male grave.
And the female graves had an egg-shaped, rounder stone on top of them.
So, not always, but if you're lucky, we will find the raised stones or the stone eggs.

And if we imagine this huge stone boulder on top of the grave, it would have been highly visible from the sea.
There were no trees here in the Viking Age, so it would have been almost like a landmark when you entered into the harbor of the town.
So, it was a chamber, a subterranean chamber made of wood, like a room underneath the earth, slightly less than 4 meters long and approximately 2 meters wide.
So, in this part, there would have been a ledge with two horses.
Cramped together, two horses very tightly packed.
And then we have the chamber with the dead woman.
When she was found, she was lying slightly on her side, so the sword would have been behind her back, at least in the position that she had when was found.
There would have been one shield at the top of the grave, in the head end, and one shield at the bottom, in the foot end.
She would have had a quiver and a bow, so her archery equipment would have been to her right side, let's say.
One spear in the cauldron, one spear to the left side of her.
And the battle knife would have been fastened to her belt, so that would also be very close in contact with the body.
We have perhaps the most interesting burial of them all, and Hjalmar Stolpe already, when he excavated, noted that this might be the most interesting and amazing burial in the whole cemetery.
Horses, weapons, shields -- everything you need to be a professional warrior -- and we now know that this warrior was actually a woman.

We don't know, but there's some reason why they're positioned as they are.
-Viking funeral rites are closely linked to their religion.
They venerated many gods, which earned them the label "pagan" from the rest of Christian Europe.
-If you ask people today, "What do you know about the Vikings?"
the one thing that everybody knows is that they go to Valhalla when they die.
-Valhalla is the mythic place where warriors who die in battle go in the afterlife.
The Valkyries select who goes to Valhalla to serve Odin, the god of gods.
-[ Speaking French ] -They either bury the dead or cremate them.
And cremation is by far the most common treatment of the dead, and that's actually what we find in most of the Birka burials.
Inhumation, burying a body, is much more rare.
-While the focus of Viking burials was typically the afterlife, that wasn't always the case.
-We normally think of Viking burials as kind of like a machine to send the dead person into the next world.
Probably most of them are.
But occasionally, you'll also find the idea that they're actually not going anywhere.
They're supposed to stay in the grave.
And it may well be that the dead actually live there.
Maybe the person in 581 lived in that grave.
-Whoever buried the woman in Bj 581 may have wanted her to remain part of the community, with her complete military arsenal.
-Inside each individual grave, it's always different in terms of precisely what objects are there, where are those objects, and probably the sequence in which it's placed.

After all, it was women, the Valkyries, who sought out the bravest fighters and led them to Odin in Valhalla.
And for Vikings, it was generally women who were in touch with magic and spirts.
-If you want to communicate with everything out there, whether it's gods or the elves that live behind your house, or the spirits of the dead, that communication is very largely through women, and that is a huge domain of power.

[ Indistinct conversations ] To become a master of arms, the woman from grave Bj 581 must have spent a large part of her life with warriors.
-[ Grunts ] [ Swords clanging ] ♪♪ ♪♪ -[ Speaking French ] -[ Grunts ] -[ Speaking French ] ♪♪ -The differences in physical strength between men and women do provoke questions about the woman in Bj 581's capability with a sword.
-A sword like this could be used by a young person, could be used by a woman.
It doesn't take an exceedingly strong physique to use it.
In fact, it's well-balanced.
It's nimble in the hand.
It's built for speed and precision, and it's to be used together with a shield as a unity.
♪♪ -[ Grunts ] -Of course, it takes lifelong training to learn how to use it properly.
♪♪ Look at the swordsmen like elite sportsmen.
These were people in society who had active lifestyle.
They were -- they were healthy until they died.
-A life dedicated to war inevitably has its share of injuries.
♪♪ Typically, years of training and violence leave scars on the body, even the bones.
♪♪ -You can never say it's a warrior.
I mean, we can see a victim of violence.
-If she were a warrior, the bones of Bj 581 would likely have the marks to prove it.
Certain injuries are indicative of sword fighting.
-When you raise your arm and you try to defend yourself, you may fracture your radius or ulna.
♪♪ This is something that could happen, and you can see that in assault victims.
But these kind of fractions may also occur indirectly when you fall on an outstretched hand.
So, these fractures in themselves can't be used as evidence for fighting.
You need something more.
-Researchers want to know whether there is evidence of these fractures on the remains.
♪♪ -Well, in case of Bj 581, I couldn't see any types of fractures on the forearms.
-While there's no physical evidence of fighting on the bones, that doesn't mean the woman in grave Bj 581 wasn't a warrior.
♪♪ -The prevalence of the weapon-related trauma in materials from the Viking Age is fairly low compared to Medieval churchyards.
♪♪ -The village where Bj 581 was found would have been no stranger to raids from other Viking gangs.
♪♪ Birka was an important trading village.
Vikings came and went.
And a merchant town was a good place to sell the spoils of plunder.
-Birka is exactly the sort of place that Vikings liked to raid.
And that means a Viking market town is just as vulnerable as everybody else's market towns.
[ Men shouting ] -There were ramparts.
There were defensive structures.
There were harbors -- pile the barricades out into the waterfront.
And a hill fort.
We're standing within the hill fort at the moment.
Protecting, defending, but also controlling all the activities down in the town.
-To ensure the merchants' safety, the town housed 40 to 60 warriors in the garrison at the bottom of the fort.
Many of these guards were archers whose job was to stop intruders while they were still far away.
A vast quantity of arrowheads was found in the soil around the ramparts -- proof of the warriors' activity.
One attack in particular left significant archeological traces.
-And when the attackers came, they came up this hill.
So, you can see, there were showers of arrowheads down on the hillside and up here.
Probably entered into that entrance because that's where we have the most heavy fighting.
-Dozens of arrowheads from all over Viking territory have been found.
There are a multitude of them, with different origins and functions.
There are some in the Bj 581 grave that have special three-faceted tips, made in Russia and capable of piercing armor.
♪♪ But the woman's remains weren't the only ones in Bj 581.
She was buried with two horses.
Skeletal remains of animals have only been found in the graves of high-ranking individuals.
♪♪ The fact that there are so many graves with horses in Birka shows it was a prosperous town.
♪♪ In addition to the two horses, Bj 581 also contained a range of riding equipment -- stirrups, a bit, spurs.
It's possible the horses were meant to join the woman in Valhalla.
♪♪ Another set of objects found in the grave suggests the woman may have planned the raids.
-On her lap, there was a pouch with gaming pieces and dice, and by her side, there was a gaming board.
♪♪ -It's rare to find a complete set, and it's rare to find a board.
When we do find those things, especially when they're very close to the body, they are almost always in graves of high-ranking military commanders.
There are a few other graves like that on Birka, a few other ironbound gaming boards, but not many.
They are all the graves of the super rich.
We don't know exactly, but it's probably hnefatafl, which is the main Viking board game.
It is like chess, in a way.
It's effectively a war game.
The idea is you have to take the King.
-There is a connection between the board game and military strategy.
Both practical, but probably also as a symbol of having acquired the knowledge of military tactics.
-So, if we know that complete sets of games like this are associated with military leaders, they're associated with an idea of military strategy, that certainly makes precisely those associations with this grave.
This is one of the reasons why we think this person is a high-ranking commander.
♪♪ -If the woman was a Viking warrior, she would likely have also been feared.
-All the clichés of rape and pillage are not just clichés.
So, presumably, this woman is in charge of things that we would regard as atrocities.
[ Shouting, weapons clanging ] -How the woman in grave Bj 581 died will likely remain a mystery.
A text refers to the swift disappearance of Birka in the middle of the 11th century.
The growing influence of Nordic royal families and Christianity likely played a role.
In 1066, Anglo-Saxons defeated Vikings on the battlefield in England, marking the end of the Viking Age.
♪♪ But several weeks later, another Viking descendant, William the Conqueror, seized England for the Normans.
In less than three centuries, the Vikings left their mark on Europe.
Their legacy was not well-documented, and as they converted to Christianity and assimilated with colonized countries, Viking identity disappeared, despite their rich heritage.
♪♪ The female warrior in grave Bj 581 has expanded our understanding of that heritage.
-A while ago, someone asked Charlotte and I if we'd like to get in a time machine and go back and meet this person, and our immediate reaction was, "No!"
I think she'd be terrifying, actually.
-I'm not sure I would like to meet her, but of course I would like to see her from afar.
I think that would be enough, actually.
-The discovery of the true identity of the person buried in Bj 581 is a fitting tribute to Viking culture.
-The Viking lifestyle, especially if you were a warrior, it was all about being remembered, and I actually think that she would have loved for us to be standing here today, talking about her and talking about her achievements more than 1,000 years later.
♪♪ -The story of the warrior from Bj 581, and Viking women, has only just begun.
