Did you know the legendary Teutonic Knights went to war against a band of vicious pirates in Gotland?

This is the story of the Gotland campaign of the Teutonic Knights in 1398 and how they destroyed their pirate enemies. 🧵

(Artwork used in this thread belongs to Joseph Feely) Image
This tale starts with the power struggle between Queen Margaret I of Denmark and the Dukes of the Duchy of Mecklenburg. Namely Albert of Mecklenburg who was King of Sweden since 1364.
Image
Image
Albert was eventually locked away in southern Sweden. Imprisoned in a castle by Margaret who sought power over Scandinavia.

From here all Margaret needed to do was lay siege to the city of Stockholm and she would have what she wanted.
In 1392 after Albert and his son Eric were imprisoned the house of Mecklenburg did not have the formal means to fight against Margaret.

She had set up a blockade at sea to while she laid siege to Stockholm. To get supplies to the city the house of Mecklenburg hired the Victual Brothers, an organized guild of privateers to run supplies through the blockade.Image
The Victual Brothers, supported by the Hanseatic League, possessed great influence over the Baltic Sea. They ran supplies through the blockade of Margaret and conquered their ships.

Their support with the Hanseatic League gave them safe harbor in the cities of Rostock, Ribnitz, Wismar and Stralsund.

However soon, in 1393, the Victual Brothers turned to piracy. Beginning with them plundering and sacking the city of Bergen.

One year later in 1394 they conquered Malmö and they plundered Turku, Vyborg, Styresholm, Korsholm as well as Faxeholm castle in Hälsingland.

With the Victual Brothers now turned to piracy and ransacking coastal towns they soon occupied the island of Gotland, Sweden.

They would set up their headquarters in the city of Visby. Image
Due to the piracy, sea trade in the Baltic sea collapsed. The situation becoming so bad Queen Margaret even reached out to King Richard II of England for aid. Image
However another player would enter the game. King Albert of Sweden would concede Gotland to his allies of the Teutonic Order as a pledge.

Under the command of Grand Master Konrad von Jungingen, the Teutonic Knights would soon invade Gotland to crush these pirates.

In 1398, the Teutonic Knights would raise an army allied with the Prussian cities of Danzig, Thorn, Elbing, Königsberg and Braunsberg.

Led by 50 Teutonic knights and Konrad von Jungingen himself, they departed from Danzig with a fleet of 84 ships and 4,000 men as well as 400 horses.Image
On March 21st the Teutonic army arrived on the shores of Gotland at Klintehamn.

The knights and their allies would storm the shores and meet initial resistance from the pirates, cutting them down before marching north to Visby.

Soon the knights would reach Visby, eventually making their way inside. On April 5th the knights would reach terms with the Victual Brothers, forcing them to surrender and leave Gotland forever.

The pirates under their new agreement had to leave Gotland immediately, anyone still on the island by the 7th would be executed.

Their goods would be taken and their castles would be burned and destroyed by the order.

The campaign by the knights was an overwhelming success. Trade in the Baltic Sea had resumed and the piracy in the waters was pacified.

The Teutonic Knights ruled over Gotland for 10 years. Even going so far as to begin construction on a new fortification on the walls of Visby which would be known as Visborg.

Years later Queen Margaret would sack Gotland and the Teutonic Order would cede the land to her in 1408.

The conflict would come to be known as the War in Gotland of 1398, or the Gotland Campaign of the Teutonic Knights.

From the spires of Lübeck to the distant shores of Novgorod, the Hanseatic League possessed influence in commerce and power.

Pirates perished, and the world’s riches flowed through their grasp.

This is the story of the Hanseatic League MEGA THREAD 🧵 Image
The Baltic Sea was a hub of trading ventures, raids, and piracy. Gotlandic sailors traveled as far as Novgorod to trade goods.

Before the Hanseatic League, Scandinavians dominated Baltic trade, establishing hubs such as Birka, Haithabu, and Schleswig by the 9th century.

Many later Hanseatic ports, including those between Mecklenburg and Königsberg, were originally part of this Scandinavian led trade network.Image
Traditionally, historians linked its emergence to the rebuilding of Lübeck in 1159 by Henry the Lion after he took the area from Adolf II of Holstein.

Modern historians presents the League as a fusion of two trade systems one centered on the Baltic and another focused on England and Flanders.Image

In around the year 1060, in modern day Belgium in the county of Flanders, one of the greatest knights in history was born.

He would grow up to be a hero of the first crusade, a hero of Christendom, a warrior unlike any other.

This is the story of Godfrey of Bouillon. 🧵 Image
Godfrey of Bouillon, born around 1060, was the second son of Eustace II, Count of Boulogne, and Ida, daughter of the Lotharingian duke Godfrey the Bearded.

His birthplace is likely Boulogne-sur-Mer, though some sources suggest Baisy, in modern day Belgium. Image
In 1076, Henry IV, future Holy Roman Emperor, deemed the duchy too critical to entrust entirely to Godfrey. Instead, Henry gave Lower Lorraine to his own son, allocating Bouillon and the Margraviate of Antwerp to Godfrey as a test of how loyal Godfrey would truly be.

Godfrey proved his allegiance by supporting Henry during the Investiture Controversy, fighting against Rudolf of Swabia, and participating in the capture of Rome.Image
