Valdemar the Wrathful and Norway’s Danish Invasion

Unknown Speaker

Welcome to the show everybody! I'm Oliver Hart, here with Marcus Hayes. And Marcus, to understand the massive, multi-century superpower we live in today, we have to start with a moment where the entire state came within an inch of collapsing into a pile of medieval rubble. I am talking about July 1337, in a damp field just south of Oslo, at a place called Follo.

Marcus Hayes

Follo! [excited] It's such a legendary name in our history books, isn't it? But Oliver, if you were a traveler standing there in April of 1337, you'd have seen something utterly terrifying. Young King Magnus VII Eiriksson, ruler of both Sweden and Norway, marching down with two thousand heavily armed Swedish troops to lay siege to Oslo. He wanted to show the Norwegian lords who was boss.

Unknown Speaker

He wanted direct royal control, yes. But the Norwegian Council of State, led by Archbishop Pål Bårdsson and the powerful Sudreim brothers, Johan and Sigurd Havtoresson, said, "No, thank you." Pål Bårdsson went to the Thing in Trøndelag and raised an entire army of Norwegian knights and free farmers. Johan raised Viken, Sigurd raised Rogaland, and by July, they didn't just meet the King -- they outnumbered him. Five thousand Norwegian troops caught Magnus in a vice at Follo.

Marcus Hayes

[chuckles] It was an absolute slaughter. The Swedish cavalry got bogged down, the Norwegian shield wall held, and Magnus VII, along with half the high-ranking Swedish nobility, was captured. And here's the kicker: Johan and Sigurd Sudreim were actually Magnus's first cousins! Their mothers were daughters of the late King Håkon V. It's the ultimate family reunion from hell.

Unknown Speaker

And the price of the King's ransom was the humiliation of his royal office. He was forced to sign the Follo Treaty of 1337. Marcus, the terms of this document are basically the Magna Carta of our modern Scandinavian structure. First, only Norwegian-born men could hold offices in Norway. No more Swedish or German favorites. Second, the Norwegian Chancellery and treasury were fully restored and strengthened.

Marcus Hayes

And it didn't stop there! [warmly] A separate Norwegian mint was established, the traditional Norwegian Landslov was guaranteed, and the local farmers' court rights were bolstered. And to seal the deal, Magnus had to dub sixty-two of the leading Norwegian nobles to knighthood right then and there. Plus, the Archbishopric of Nidaros got total freedom to elect its own bishops without royal meddling.

Unknown Speaker

[measured] It is a total surrender of absolute royal prerogative. Magnus also agreed that any future war required Norwegian consent if Norwegian resources were to be used, and all Norwegian taxes had to be spent solely inside Norway. But the most radical part was the physical restriction on the crown: Magnus had to be officially crowned in Oslo Cathedral, and he and his court were legally required to spend at least four months of every year living in Norway.

Marcus Hayes

It literally split the court! [laughs] Suddenly, this young king had to pack up his Walloon wife, his mother Ingeborg, and half the Swedish administration, and drag them to Oslo. But you know, Oliver, despite being forced to sign at sword-point, they actually held a massive festival, an Olsok feast in Oslo, just days after the battle. It shows how pragmatic these medieval lords were. "We've captured you, we've stripped your power, now let's have a drink because we're still cousins!"

Unknown Speaker

Now, this forced residency in Oslo from 1337 to 1345 had a fascinating side effect. It triggered what historians call the Golden Age of the Norwegian High Nobility. Because the Chancellery was restored to Oslo, the written Norse language didn't die out or get replaced by Swedish or Danish dialects. It became a prestigious administrative language.

Marcus Hayes

This is the moment our written tradition was saved! [excited] And it wasn't just dry legal documents flying out of the Chancellery. In 1338, a monk from Stavanger named Elvar Håreksson started writing down the new sagas. He wrote "The Saga of Magnus Lawmender and his Sons," reviving the whole classical saga-writing tradition that had been dormant for decades. Without Follo, we might not have the sagas of Magnus VII or Magnus VIII today.

Unknown Speaker

Indeed. And culturally, Oslo became a melting pot. The Queen's Walloon knights brought European chivalry and heraldry with them. Suddenly, these old Norwegian land-owning clans -- who used to just be regional chieftains -- adopted European-style coats of arms. This is when the great noble houses we still talk about today really solidified their identities: the Sola, the Sudreim, the Teiste, the Smør, the Benkestok, and the Rømer.

Marcus Hayes

I love looking at the heraldry of this era. [thoughtfully] You see the old Norse lion being combined with continental checks and bars. They even created a new royal quadrant standard: the Norwegian and Geatish lions quartered together. It was a visual statement that Norway was no longer a provincial backwater -- it was a sophisticated, chivalric European power.

Unknown Speaker

And this newly confident nobility started throwing its weight around internationally. They aggressively asserted Norwegian claims over the northern islands and Scotland. In fact, relations between Magnus VII and the Scottish King, David Bruce, got so tense that Norway became a safe haven for outlawed Scottish nobles who hated David. One of them, George Sinclair, ended up founding the Norwegian branch of the Sinclair family, which remained a powerhouse of our high nobility for centuries.

Marcus Hayes

It's incredible how a defeat in a field in Follo ended up exporting Norwegian influence all the way to the Orkneys and the Scottish Highlands. [chuckles] But back home, Magnus's personal life took a sharp turn. His Walloon queen died in childbirth in 1338. He quickly remarried Helvig of Schleswig, sister of the former Danish King Valdemar. And in 1342, she gave birth to twin boys: Olav and Håkon.

Unknown Speaker

[measured] The twins. And to keep the Norwegian nobility happy, Jon Sudreim was appointed guardian for Olav, and Sigurd Sudreim became the guardian for Håkon. It seemed like a perfect domestic peace. But while Norway was thriving under this aristocratic balance of power, across the border, Sweden was beginning to rot.

Unknown Speaker

By 1345, the Swedish nobility had had enough of Magnus VII. They felt he was spending too much time in Oslo, favoring Norwegian lords, and spending Swedish tax money to keep his cousin-lords happy. And then Magnus made a catastrophic mistake: he tried to introduce a unified, royal "Land Law" in Sweden to curb noble privileges.

Marcus Hayes

And Sweden exploded. [gasp] The Swedish Council, led by Halfdan Bure and Archbishop Hemming Nilsson, rose in open rebellion. Magnus and his court literally had to flee for their lives across the border back to Norway. He arrived in Oslo with nothing but the clothes on his back, begging his Norwegian vassals for help to win back his Swedish crown.

Unknown Speaker

And the Norwegian Council, being shrewd politicians, said, "We will help you, but it'll cost you." They demanded that after the Swedes were defeated, Norwegian nobles would get lucrative administrative posts inside Sweden. Magnus agreed, and in June 1346, a Norwegian army of three thousand men and a hundred elite knights crossed into Sweden. This led to the Battle of Skara.

Marcus Hayes

Skara is such a brutal example of professional chivalry versus raw numbers. [measured] Halfdan Bure had raised a massive Swedish peasant militia. But these were farmers with scythes and axes. The Norwegian knights, armored in modern plate and led by veteran commanders, absolutely crushed them. It was a bloodbath.

Unknown Speaker

But the victory was short-lived. Sensing Magnus's distraction, the brilliant and ruthless Valdemar IV of Denmark -- known to history as Valdemar Vræde, or Valdemar the Wrathful -- launched an invasion of Scania. But Halfdan Bure's Swedish rebels managed to turn around and utterly defeat Valdemar in March 1347, forcing the Danish king to flee back across the Øresund in massive debt.

Marcus Hayes

The whole Baltic was in chaos. [sighs] And then came the disaster at Örebro in August 1347. Magnus's combined Norwegian-royalist force met Bure's main rebel army. It was a catastrophic defeat for the Bjelbo loyalists. And the biggest tragedy for Norway was the death of Sigurd Sudreim, the Marsk of Norway and leader of the King's guard. He died fighting in the front lines.

Unknown Speaker

The death of the Marsk broke the Norwegian war effort. By May 1348, Magnus had to sign a peace treaty. He kept Norway and the strategic island of Gotland, but he was forced to abdicate the Swedish throne entirely. The Swedish council then elected Johan of Mecklenburg as their king, because he was descended from Magnus's sister, Euphemia Bjelbo. The union with Sweden was dead.

Marcus Hayes

But Magnus never truly let it go, did he? [laughs] He refused to take the Swedish three-crown symbol off his coat of arms. Instead, he turned Gotland into a legalized pirate haven! Norwegian, Danish, and German privateers, flying the Norwegian flag, spent the next decade harassing Swedish and Mecklenburg shipping in the Baltic. It was a cold war fought with letters of marque.

Unknown Speaker

But all of these geopolitical games, the pirate havens, the claims on Sweden -- they were all brought to a screeching halt by the arrival of the Great Mortality. The Black Death hit Scandinavia between 1349 and 1351. And Marcus, the demographic numbers from this period are just staggering.

Marcus Hayes

They are heartbreaking, Oliver. Let's look at the actual census data we have from 1345 compared to 1351. Denmark went from eight hundred thousand people down to three hundred and seventy thousand. More than half the population wiped out! Sweden and Finland dropped from nine hundred and fifty thousand to five hundred and seventy thousand.

Unknown Speaker

And Norway, including the Atlantic islands, fell from four hundred and seventy thousand to three hundred and forty thousand. Now, while Norway lost a massive portion of its population, the political outcome here was radically different from the rest of Europe. In Denmark and Sweden, the loss of labor led to harsher serfdom. But in Norway, it actually strengthened the peasantry.

Marcus Hayes

This is because of the Fridhkarlslogin of 1353 -- the "Free-man Laws" declared by Magnus VII. [warmly] Because so much agricultural land was left empty, the remaining farmers had immense leverage. Magnus legally secured their Thing rights and actively incentivized them to buy the land they worked on. The Church and the old feudal nobility, who relied on tenant rents, were hit incredibly hard. But the free Norwegian farmer became a self-owning political class.

Unknown Speaker

[thoughtfully] It's a fascinating administrative pivot. To replace the weakened feudal lords, Magnus introduced the 'Syssel' system, inspired by his close trading partner and pen-pal, King Edward III of England. He divided Norway into administrative districts centered around local courts or towns, run by royal "Sysselmenn" who had to be knights. It was a highly efficient, crown-directed bureaucracy.

Marcus Hayes

Imagine a medieval king having a pen-pal in Westminster! [laughs] But that trade alliance with England saved Norway's economy. While Denmark was burning and Sweden was fracturing under German debt-lords, Norwegian timber and fish were flowing directly to England in exchange for grain and silver. Out of the ashes of the plague, a more modern, centralized state was being born.

Unknown Speaker

As we enter the late 1350s, the political map of Scandinavia had completely transformed. In 1355, Magnus VII officially declared his younger twin son, Håkon Magnusson, as his sole heir to the Norwegian crown. Now, Marcus, this caused a massive rift with the Sudreim family, because Jon Sudreim had been the guardian of the older twin, Olav.

Marcus Hayes

Oh, Jon Sudreim was absolutely furious! [excited] He felt his ward had been cheated of his birthright. But Magnus chose Håkon for very practical reasons: Håkon had inherited the title of Marsk from his late guardian, Sigurd Sudreim. He was a brilliant military commander, trained by Sigurd himself, and he was deeply loved by the high nobility.

Unknown Speaker

To secure the dynasty, Magnus arranged two massive marriages. In 1358, the young Crown-Prince Marsk Håkon married Margaret Plantagenet, the daughter of Edward III of England. The next year, Olav was married to Elisabeth Gryf, daughter of the Duke of Wolgast. The Bjelbo dynasty was now tied directly to the most powerful crowns in Western Europe.

Marcus Hayes

Meanwhile, down in Denmark, Valdemar Vræde was executing disloyal nobles and trying to squeeze taxes out of Slesvig. When Slesvig's duke refused, Valdemar literally had him murdered and claimed the duchy for himself. This was a direct attack on Magnus's family -- remember, Magnus's queen, Helvig, was a Slesvig princess. Her inheritance was being stolen.

Unknown Speaker

And that, Marcus, is where the fuse is lit. In 1358, Magnus VII declared war on Denmark. He raised an unprecedented army of eight thousand men -- Norwegian knights, free farmers, English longbow mercenaries, and Irish-Gaelic gallowglasses. Two hundred ships assembled in the Oslofjord, led by the legendary royal flagship, the "Ormen Lange," flying the red, blue, and gold Bjelbo banner.

Marcus Hayes

It's a breathtaking image to end on. [reflective] A grand coalition of northern powers sailing south to challenge the Wrathful King of Denmark. The stage is set for a clash that will either forge a united Scandinavian empire or drag the whole North into a century of blood.

Unknown Speaker

And that is where we will pick up next time. Thank you for listening to the Scandinavian History Podcast. I'm Oliver Hart.
