Harald Bluetooth King of Denmark and the Power of Connection

Before Bluetooth connected your earbuds to your phone… it connected kingdoms.
Well—sort of.

In this episode of Viking Legacy and Lore, we dive deep into the saga of King Harald “Bluetooth” Gormsson—the Viking monarch who didn’t just rule Denmark… he united it, converted it, and—centuries later—inspired the name of the wireless tech you use every day.

Yeah. That guy. The one with the dead tooth.

We’ll explore how this larger-than-life Viking king forged something far more valuable than alliances or war victories. He forged connection—between tribes, between faiths, and (eventually) between devices.

🔹 Who was Harald Bluetooth, really?
 🔹 Why did he convert to Christianity—and was it spiritual, strategic, or both?
 🔹 What was the dramatic fallout with his rebel son, Sweyn Forkbeard?
🔹 And how did a 1990s tech engineer reading Viking history books decide to name a global wireless protocol after a man with questionable dental hygiene?

You’ll also discover:

• The legendary “hot iron miracle” of Poppo the priest
• How Harald’s decisions reshaped Scandinavia forever
• Why the Bluetooth logo is actually made of ancient Viking runes (yes, seriously)
• And what all of this has to do with your own ability to connect—in a fractured, noisy world

🧠 This isn’t just history. It’s a mirror.

Harald’s story reminds us that real connection is never accidental. Whether you're trying to unite a kingdom, lead a family, or just get your AirPods to sync, the principles are the same:
Connection takes courage. Effort. And yes, sacrifice.

So we’ll end this episode with a surprising, soul-hitting takeaway on what it means to connect in the digital age—not with noise, not with likes, but with real presence.

📱 From fjords to firmware. From Jelling stones to JavaScript.
This is the story of how a Viking king still lives on—in your pocket, your dashboard, and maybe… your values.

 📍  📍 Bluetooth during the Viking age was more powerful than its modern predecessor. That's because Bluetooth, the Viking King, he's the one who connects us all. Before wireless earbuds, before smartphones, before your smart fridge could talk to your smart toilet, there was a Viking King. He didn't have the same technology that you have.

He didn't stream Spotify. He didn't play Pokemon Go, But he did unite warring tribes.

\ Had a Bluetooth and left behind a legacy. So powerful. It's literally in your pocket right now. His name Harold Bluetooth. And after you hear the real story, you won't just connect the dots between Viking warlords and wireless technology. You'll never look at your Bluetooth icon the same way again.



Spoiler alert, its Ancient ruins. Seriously. In this episode of Viking Legacy and Lore, we're bringing together the influence of Vikings on modern life and powerful lessons that we can learn from leaders that have clearly left their mark centuries later. This is the saga of King Herald Bluetooth. A man whose life was filled with war diplomacy, religious upheaval, and some serious dental drama.





In this episode, you'll learn exactly who Harold really was and why this bearded ax wielding monarch. He matters more than your earbud pairing issues.

You also find out why his conversion to Christianity wasn't just a spiritual shift, it was political TNT for the Viking age.



We'll also touch on how Bluetooth technology got its name from a guy who had zero interest in apples or droids. But he did manage to sink an entire kingdom. And when I say sink, I mean unite. And we're just warming up. We're gonna walk through the legendary trial by Fire Miracle that helped 

 📍 seal

Harold's fate and faith, 📍 

by the end, you might just realize that building real human connections across divides through traditional barriers and even through awkward zoom calls isn't just a modern challenge.



It's existed for centuries. But uniting, connecting, well, that is a true Viking virtue. So grab your horn of mead and your overpriced coffee and your $50 Yeti mug 

Because it's time to discover how a dead tooth and a legendary Viking king lives on in ways you didn't even know  

Harold Bluetooth was born around nine thirty five ad the son of King Gorm, the old.

His father, Gorm is remembered as the first real king of Denmark, a serious, stubborn man who stayed loyal to the old Gods. 

His mother Thyra was just as famous old writers called her Denmark's adornment, and they remember her as wise and forward thinking. Harold was born into a Denmark that wasn't yet a real country. The borders changed. Often tribes fought constantly in nearby kingdoms like the Holy Roman Empire to the South, and the Norwegians to the north wanted more control over the region.



Harold inherited a crown. It was more of a dream than a stable throne. His kingdom was held together by fear, loyalty, and the strength of the acts.

Harold's early life was sharpened by challenges. when Gorm died around 9 58, Harold became king, but it didn't mean everyone followed him. 

Local rulers were proud and didn't like being told what to do. On top of that, foreign powers like King Otto of the Holy Roman Empire, they were looking to move in and take advantage. The Germans, the Saxons, the South, they wanted more land and more Christians. Harold couldn't hold Denmark by force alone.

He had to use smart diplomacy and sometimes even submission to keep peace and stay in power. 

Harold was clever. He knew when to fight and when to talk. 

around nine 70. He even pushed Danish control into parts of Norway, but it wasn't easy. Rivals from the north. They fought back and even made Harold retreat more than once. Still for a short time, a United, Denmark, Norway existed under Harold's name.

Harold played the long game. He used buildings, laws, and big symbols to hold his people together.

Unlike many Viking Kings known only for fighting. Harold left behind. Things you can still see today. Bridges that he built, some of the first large wooden bridges in Denmark. 



One of these bridges was almost 250 meters long. They weren't just for crossing rivers, they were for connecting the land and his kingdom together. Harold also built huge forts and fortresses, and you can still see them today. They were built with careful planning, not by random warriors. These were forts that showed Denmark had a strong, smart ruler behind them.



Harold knew when to use peace and when to use power to reward and to threaten if a local yal joined him willingly, they receive gifts and support. If they refused, they risked war with Harold. He knew that sometimes kindness built loyalty and sometimes fear kept order, and then came the famous Christian missionary Poppo. So how did Harold become a Christian? That's the question.

Why did he become a Christian? lemme just tell you, is still debated, but the most famous story involves a missionary name Popo, according to old books. We'll talk more about this in a moment.

Popo was told to prove that he was God's messenger. He had to hold a red hot iron in his bare hand. The test was simple. If he didn't get burned, his God must be true. in a room full of warriors, Popo held the glowing iron. He walked across the hall and when he let go, his hands weren't burnt at all. Everyone gasped. And Harold the story says, bowed his head and believed, was this a true story? Was it real? Maybe. But historians think that it was probably politics that played a major role. Harold was caught between German Christian rulers to the south and pagan warriors to the north. 

Becoming Christian helped him earn favor with powerful neighbors and still hold onto his throne even if the miracle was exaggerated. The story gave Harold a way to bring Christianity to Denmark without losing honor.



Harold is also responsible for creating the gelling stone, which is located today. You can still see it in gelling Denmark. It's considered the birth certificate of Denmark, and it was to show what he had done.

Harold carved this stone with ruins and it says, king Harold ordered this monument made in memory of Gorm his father and Thra his mother. That Harold, who won for himself all Denmark and Norway and made the Danes Christian, the stones even have a picture of Jesus with his arms outstretched on the cross.

On one side. Today that stone still stands next to the burial mounds of Harold's parents historians call it Denmark's birth certificate. The moment the country became a United Kingdom under one king, under one law and one faith.

Harold knew that Denmark needed to stand strong or be taken apart by strong powers, By carving his name in stone, he made a bold claim. This land is one. These people are one. And the faith. It is now Christian. The stone has lasted longer than Harold, longer than his dynasty. 

a thousand years later, it still reminds us the power of unity, of vision and belief. So why was he called Harold Bluetooth, the name, that would echo through a thousand years.

Why the name Bluetooth, this name that would echo through thousands of years and continues on today, whether people even realize its origins or not In old Norris's nickname was Blaton, literally meaning blue tooth. Medieval riders say that Harold had a blue tooth or a tooth that had turned dark, and most people think it was probably from an injury. It could have been a disease or decay.

Others say maybe it was a battle wound that left the root blackened, whatever the reason, it definitely stood out. And this was a time when Warriors had all kinds of nicknames. Fork, beard, fair hair, blood acts, and now Bluetooth. what started as an insult or maybe a jab became a badge of honor and a thousand years later. Tech companies decided to use this very name to represent wireless connection.

Even the Bluetooth logo is made by combining Harold's initials from ancient Viking ruins. It's like a digital gelling stone etched, not in rock, but across every device in your pocket. 

There's something important about Harold that most people don't talk about, not even in history class. His reign wasn't just about crosses and carvings. It was about pulling everyone together. Before Harold Denmark was a land of scattered tribes. Chiefs ruled their own corners and only helped each other when it suited them.

But after Harold Denmark became a true kingdom with roads, forts, a real army, and even early taxes. Yes, he brought Christianity, but he also brought order. Some historians say Harold's greatest gift wasn't religion. It was. Vision that united people, he didn't just fight battles, he built the system and symbols that gave Denmark its strength.

And because of that, later kings

were able to rule mighty empires without Harold's bridges, forts, and bold ideas, there may have never been a North Sea Empire at all.

Even with all his big ideas, Harold's story doesn't end with a win, but it ends with betrayal. His own son turned against him. Some say Harold died in battle around 9 85, wounded and forced to run, only to die soon after on the island of Warland in what is now Poland. Others think that he lived longer, hiding far from home. Old stories, they don't agree.

Go to the churchyard in gelling today, and you can still see what he left. A great stone worn by a thousand winters. Still it stands, his message still carved in it. Denmark had its beginning and between the hammer and the cross between father and son. Harold's story still speaks through time. Real unity. always comes with a cost. Harold Bluetooth's baptism wasn't just a personal choice, it changed Denmark's path. It was a quiet moment that helped shift the whole Viking world.

Many historians see it as one of the first signs that the Viking age was beginning. To end baptism and the cross. The old stories don't all agree on why Harold was baptized. Some say it happened in Germany. Others say it was in Denmark, maybe near gelling, but they all agree on the moment. A king who once swore Thors hammer now bowed before the cross.



He would build churches in Danish lands and welcome Christian teachers to baptize his people.

Why did he do it? maybe Harold truly believed. Maybe he was moved by the stories of Jesus miracles or by the famous tale of Popo, the priest who held that red hot iron to prove his faith. But Harold was also a ruler. He knew faith could be powerful by becoming Christian. He didn't just find salvation, he found legitimacy to the south.

The Holy Roman empire ruled by Otto the first and later by Otto the second. It was strong, and staying a pagan king made him a target. Becoming a Christian King made him an equal. Christianity also gave Harold a way to bring his people together to unite them. Paganism in Denmark was messy. Some people worship Thor, others Odin.

Each valley had its own sacred sites, but Christianity was united. One God, one church, one ruler. If his people followed the same faith, they might follow his throne more closely too. And then there was the money. Christian Europe was linked by trade networks, merchants from Saxony, Flanders, even Italy. They trusted Christian lands more than Pagan. 

With baptism, Harold gained access to the coin, to the markets, to new alliances for a kingdom between the Baltic and North Sea. That was a big deal.

But Harold's plan for unity. backfired his son rebelled. He remained loyal to the old gods. To him, his father's baptism felt like giving in, like handing power over to foreign leaders and betraying the ways of their ancestors. Many Viking warriors agreed. They still believed in Thor's hammer. To them, Christ was a Southern God. Weak and strange.

Civil war broke out battles burned across yoland and Zealand.

Harold was badly wounded and fled into the island of woolen or so they say, . Strangely enough, his son, who once fought to protect the old gods, would later become Christian too.

and maybe even more influential in that way.

Harold's choice to become Christian. changed Denmark forever. I'm gonna tell you why I think it matters the most. Christianity helped bring everyone under one system, one ruler, one God, one law. The cross became the symbol, a symbol of a stronger kingdom.

The Holy Roman empire was still a very strong force in Europe. Harold's baptism let him deal with them. King to king, not like a pagan outsider. This meant better trade for the Danes. Christian merchants trusted other Christians, and during Harold's reign, Denmark saw a wave of new goods, silver coins, jewelry, wine, silk.

Instead of stealing wealth through raids, Denmark now earned it through its markets.

Denmark was the first Viking country to become Christian, truly Christian, and it became the starting point for the rest of Scandinavia. From Denmark. Christian missionaries were sent north into Norway. 

One Viking King Olaf. had been a Raider, he returned home baptized

and as the story goes. He told everyone to convert to Christianity and he didn't ask nicely. He burned temples and he gave people two choices. Baptism or death? 



Sweden remained pagan for a long time, but slowly Christianity influenced spread thanks to the pressure from Denmark and Germany.

And so just to give you a quick overview of how this all took place, Denmark under Harold, Bluetooth around the nine sixties converted to Christianity. Then it was in Norway with Olaf from 9 95 to about a thousand. Norway had a huge conversion moment, and then Sweden slowly converted from the 1000 to the 11 hundreds.

And then it continued to spread into the neighboring places outside of Scandinavia, like Iceland. And so in the year 1000, they all converted. They even voted on it, uh, Greenland. Around the same time, Leif Erickson brought Christianity to that giant island.



And what I wanna point out is that that is the reason why every Scandinavian flag today has a cross on it. It all started with Harold's baptism. The North once ruled by Viking gods is now marked by the sign of the cross 

And whether it was by peace or by force for political reason, or it was genuine faith.

The reality is Harold Bluetooth, he spread Christianity through Scandinavia and beyond.

Harold built churches carved stones, and he preached unity. But even with kindness, he lost his throne. In the end. Other Viking kings, they weren't so gentle. As we mentioned Olaf, he forced people into rivers to be baptized.

He even burned temples and punished anyone who refused the new faith.

And in Norway there was another Olaf who became King, and he kept that theme going. He ruled with it even harder hand until he was killed in battle in 10 30.

Here's something to ponder. A lot of people think that the Vikings conversion to Christianity led to the end of the Viking Age, but what if Harold Bluetooth hadn't become a Christian when he did? Denmark may have been invaded by the Holy Roman Empire. Otto, the great, he was powerful and he was eager to expand his territory.

And without Harold's baptism, things might have looked a lot different. With a pagan ruler, Otto would've had no problem invading Denmark and taking the land for himself, thus, maybe even ending the Viking age sooner than it did.

And we may not even have Denmark as we know it today. 

We definitely wouldn't have had the jelling stones and maybe even limited raids. Into England. From that point on, there would've been no canoe, the greats, rural Scandinavia and the British Isles. There would be a lot of things that would've changed if Harold hadn't been baptized.

So it's quite possible that Harold's salvation was actually the salvation of Denmark. Now, next time you see a cross on a Scandinavian flag, remember it's more than a symbol of faith. It was a symbol of survival.  

a moment ago, we touched on the famous story, the one where the missionary came and held the glowing piece of iron in his hands. That moment that helped turn Harold Bluetooth from a Viking king into a Christian ruler. But I wanna take a quick look at that story and what really happened. What might be legend and

why it still matters today. Here's how the story goes. Sometime in the nine sixties, Harold Bluetooth had a problem. He was the king of Denmark. His rule was not secure. Many Viking leaders still followed the old God. Some thought Christ was weak and definitely a foreign God. German rulers to the south were pressuring Harold to become a Christian, but he needed to prove.

Not just for himself, but for his people. He wasn't gonna believe in something that wasn't real, and he certainly wasn't gonna encourage his people to do the same. That's where Popo came in. He stepped forward. The warrior leaders of Denmark, they didn't care about words. They believed in trial by fire. They wanted to see a test to prove it so.

they challenged Popo, carry this red hot iron in your bare hands. If God is real, then you won't be burned. Well, that night they filled up the hall, they packed it tight, torches burned. The iron was pulled from the fire, glowing hot. Everyone expected Popo to scream and to fail, but Popo prayed and he picked it up with his bare hands. He walked across the hall holding the red hot iron, the smell of smoke. It was in the air. When he put the iron down, His hands were unburned. There were no blisters, no wounds.

The hall went silent, and as the story records, 

Harold, at that moment, bowed his head and said. This is the true God. Now, it sounds like something from a Viking saga, but did it really happen? See, the story comes from old Christian books written by church leaders. They wanted to show that miracles prove Christianity was true. 

But historians today, they like to point out that there's no Danish record of Harold's time in this trial. 

the people who wrote the Chronicles and these stories were Christians, so it's hard to see them as, uh, neutral players.

But then again, during the Viking Age, written history on the Viking side was very uncommon. That's why things like the jailing stone are so important because it's literally written history, but there's so few words there that we have to imagine The rest.

So it is possible that the story is true, but it's also possible that it was made up or dramatized.

And to be honest, the reality is we will never know for sure, but what we do know is that the story spread, it spread to the Danish people. It's been talked about as the moment that the king became a Christian,

and we know from history that it kept going, it kept spreading, and it continued through all of Scandinavia and beyond. So it had an impact one way or another.

I would love to hear your thoughts on whether it's true, whether it's not true. Whether miracles are real or miracles are just made up for convenience. 

Tell me your thoughts in the comments. Start a conversation. Just keep it cordial. 

Now over a thousand years later, Bluetooth would have his name resurrected.

In the late 1990s, engineers from Intel, Nokia, and Ericsson, they wanted to solve a problem. They were trying to make computers, phones, and other devices talk to each other wirelessly. But each company had its own way of doing things, and no one could agree on an exact method. That's when one engineer from Intel, he got the idea.

He'd just been reading a book about Viking history, not because he was Scandinavian, but because it was interesting, the story of Harold Bluetooth stood out. a king who united different tribes into one kingdom.

this engineer thought that's exactly what we're trying to do, unite technology. So they gave the project a code name Bluetooth. At first it was just a placeholder, a temporary name, a secret identity for this project. But the name stuck. And just like Harold's Kingdom, the technology wasn't perfect at first.

Devices wouldn't always connect. Systems seemed to clash. It took time, effort, teamwork, and eventually it did work. And when it was time to launch. They kept the name Bluetooth to honor the king who brought people together. And again, even the logo has a secret Viking twist. It's made from two old ruins, the Viking letter for H and for B Harold Bluetooth's initial.

Put together, they make the Bluetooth symbol. It's modern, it's simple, but it's Viking to the core.

Today, Harold Bluetooth's name is everywhere. It's in your phone, your earbuds, your smartwatch. Every time you turn on Bluetooth, his initials light up in your pocket. Few medieval kings have left such a surprising legacy. And here's something even cooler. Bluetooth technology mirrors Harold's life both brought different groups together. Both had setbacks and challenges.

Both became part of something much bigger.

So here's a lesson. Unity is not always easy, whether it's tribes of people or technology. Bringing things together takes vision, patience, and courage. And just like Harold, the story doesn't stop there because up next we're gonna explore what his choices meant. Not just for Denmark, but for the future of all the North.

His decisions, they still echo across Europe today. When Harold Bluetooth carved his name into the stones at yelling, he wasn't just bragging about winning battles, he was sharing a dream. The Viking tribes who used to fight each other could stand together. He believed the future didn't belong to people who stayed divided, but to those brave enough to unite.

That's the center of the story, the connection. The real legacy of Harold Bluetooth isn't wireless. It's a reminder. Connection is what makes us strong. 

Connection isn't just for data and devices, it's for people. We need connection. We need each other. We need a team of loyal friends, people who've got our back, people who will walk through the fire with us, so make those connections.

We need people around us, surrounding us friends to laugh with people to help carry the load.



What we need, what we want, what we're really after is genuine connection. It's not about likes and followers, it's about real connection. Someone who knows your name, someone who cares, someone who looks forward to what you're gonna say. Because it matters and it speaks to them.

That was one of the ideas behind this podcast is to create a community where Viking fans can come together and talk and share the principles, the things that they've gleaned, shared on YouTube, and the comments on Facebook and our group.

Look, the Viking journey is real. Even though the Viking age has ended, there are so many of us that can learn so much from the Vikings, the principles that they live by, the honor code .Their desire to adventure, to explore, to build kingdoms and empires and trade networks. It's all there for us. If we're looking and let's share together, let's share and make those connections and tell each other what we found in these episodes of what we found as we've read the sagas share and do your part 

You can share your thoughts in the YouTube comments. You can post on the Facebook page, you can join our Discord. We are there to connect with you.

Harold Bluetooth, United Kingdoms. 

so what if you could help connect people with each other? Every time you talk with someone, every time you send a message, every time you share your thoughts and your insights and start a conversation online, you're starting to develop those connections. The key is do it with kindness. Do it with gratitude.

Do it with connection and unity in mind. Will this comment produce unity? Will it take us a step closer to, to. Connection or is it a comment that will drive people apart? Because if that's the case, then it's not necessary because what we desire is to connect. So, uh, make sure that when you post, when you comment that it's done with, with kindness and care.

We've even seen how connection completely changes lives in the course of entire nation. So that's the power that we have right here, right now. 

I'll leave you with this final thought. Strength comes from connection. Legacy comes when we stand together, and if we believe that, if we actually live that out, then this story isn't just history anymore. It's our story. It's your story. And so if something in this episode stirred your heart, don't keep it to yourself.

Share it. Leave a review, send it to someone who needs to hear it, because that's the point of Bluetooth and that's the point of this podcast to share the stories and to make connections. The Stones Herald Rays still stand. The room still speak, and now it's your turn. So step out, build bridges, forge connection, and let your story echo.

Until next time, be bold, be strong, and awaken the Viking in you.
