Valdemar IV Eriksøn (born c. 1262, died 1312) was Duke of Schleswig from 1283 until his death in 1312. He was the eldest son of Duke Eric I of Schleswig and Margaret of Rugia.

Duchy of Schleswig region between Germany and Denmark

The Duchy of Schleswig was a duchy in Southern Jutland (Sønderjylland) covering the area between about 60 km north and 70 km south of the current border between Germany and Denmark. The territory has been divided between the two countries since 1920, with Northern Schleswig in Denmark and Southern Schleswig in Germany. The region is also called Sleswick in English.

Eric I, Duke of Schleswig Duke of Schleswig

Eric I Abelsøn was a Danish nobleman. He was the ruling Duke of Schleswig from 1260 until his death in 1272. He was the second son of King Abel of Denmark, Duke of Schleswig and Mechtild of Holstein.


Early life

At the death of his father Duke Eric I in 1272, Valdemar was only about 10 years old. For the following ten years, King Eric V of Denmark, feudal overlord over the Duchy of Schleswig, refused to install Valdemar in his father's duchy. Only in 1283, at a meeting of the Danehof in the city of Vordingborg, did the Danish magnates force King Eric to install Valdemar as duke. In 1284 he granted city rights to the city of Flensburg.

Eric V of Denmark King of Denmark

Eric V Klipping was King of Denmark (1259–1286) and son of King Christopher I of Denmark. From 1259-1266, he ruled under the auspices of his competent mother, Margaret Sambiria (1230-1282). Between 1261 and 1262, the young King Eric was a prisoner in Holstein following a military defeat. Afterwards, he lived in Brandenburg, where he was initially held captive by John I, Margrave of Brandenburg.

Danehof was the name of the Danish medieval parliament which played a certain role between c. 1250 and 1413.

Vordingborg Place in Zealand, Denmark

Vordingborg is an old ferry town in Vordingborg Municipality in Denmark with around 18.000 inhabitants. Because of three large estates surrounding the town, a coherent urban development has not been possible, which is the reason why three satellite towns have emerged around the town. Within the ring of estates, the town has 12,000 inhabitants, and 18.043 inhabitants when including the three satellite towns of Ørslev, Nyråd and Stensved, situated 1, 3 and 5 kilometres, respectively, from the town of Vordingborg. Vordingborg Municipality (Kommune) has a population of 46,000.

Duke of Schleswig and conflict with the King

However, Valdemar was not content and also claimed the island of Als, as well as the Crown lands of Schleswig. When in 1284 a judgment of the Danehof ruled against the claims of Duke Valdemar, he occupied the island of Als by force. However, the military campaign proved disadvantageous for the duke, and as he intended to travel north to gain support in Sweden and Norway, he was captured by King Eric and confined at Søborg Castle in 1285. He was released the following year on condition that he abandoned almost all of his claims.

Sweden constitutional monarchy in Northern Europe

Sweden, officially the Kingdom of Sweden, is a Scandinavian Nordic country in Northern Europe. It borders Norway to the west and north and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund, a strait at the Swedish-Danish border. At 450,295 square kilometres (173,860 sq mi), Sweden is the largest country in Northern Europe, the third-largest country in the European Union and the fifth largest country in Europe by area. Sweden has a total population of 10.2 million of which 2.5 million has a foreign background. It has a low population density of 22 inhabitants per square kilometre (57/sq mi). The highest concentration is in the southern half of the country.

Norway constitutional monarchy in Northern Europe

Norway, officially the Kingdom of Norway, is a Nordic country in Northwestern Europe whose territory comprises the western and northernmost portion of the Scandinavian Peninsula; the remote island of Jan Mayen and the archipelago of Svalbard are also part of the Kingdom of Norway. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land.

Murder of King Eric

Just half a year later, in November 1286, King Eric was assassinated, and Duke Valdemar naturally fell under suspicion. The Queen Dowager, Agnes of Brandenburg, apparently shared the suspicion, but feared open aggression with the Duke. Instead, his support was achieved by accepting his claims and appointing him regent of the kingdom during the minority of King Eric's under age son and successor, Eric VI.

Not to be confused with Agnes of Babenberg

Eric VI of Denmark King of Denmark

Eric VIMenved was King of Denmark (1286–1319). A son of Eric V of Denmark and Agnes of Brandenburg, he became king in 1286 at age 12, when his father was murdered on 22 November by unknown assailants. On account of his age, his mother ruled for him until 1294.

Renewed conflict with the King

Already in 1289, the confidence between Duke Valdemar and Dowager Queen Agnes was breached and a clash occurred between the Duke and the followers of the Queen. Shortly after, Duke Valdemar even entered into a league with King Eric II of Norway, then at war with Denmark. Apparently, in 1295 Valdemar suffered a defeat at a naval battle in the channel of Grønsund. In 1297, a final settlement was concluded where Duke Valdemar among other things abandoned his claims to the disputed island of Als.

Eric Magnusson was the King of Norway from 1280 until 1299.

Grønsund is a strait in Denmark separating the island Falster from the islands Møn and Bogø. Grønsund's maximum depth is at approx. 20 metres and the width is between 1 - 4 km. Storstrømmen channel is situated to the west and Stege Bugt lies to the north between Zealand and Møn. A ferry crosses the channel in the summertime from Stubbekøbing to Bogø island. Grønsund has several shallow areas, i.e. near Bogø, and has a strong and alternating current. Both submersed and riparian vegetation is rich, and the sound is an important breeding area for wildlife and fish. Many shore birds, including cormorants, mute swans, greylag geese, pintails, shovelers, eiders, avocets, several species of waders, as well as gulls and terns are breeding in the area. The porpoise lives in the area.

Minor disputes with King Eric VI continued during the following years. On a whole, however, the Duke was hence on friendly terms with the King and supported him in his wars in Sweden and the Holy Roman Empire. In 1311 he participated in the magnificent tournament held by King Eric in Rostock.

Holy Roman Empire varying complex of lands that existed from 962 to 1806 in Central Europe

The Holy Roman Empire was a multi-ethnic complex of territories in Western and Central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806 during the Napoleonic Wars. The largest territory of the empire after 962 was the Kingdom of Germany, though it also came to include the neighboring Kingdom of Bohemia, the Kingdom of Burgundy, the Kingdom of Italy, and numerous other territories.

A tournament is a competition involving a relatively large number of competitors, all participating in a sport or game. More specifically, the term may be used in either of two overlapping senses:

  1. One or more competitions held at a single venue and concentrated into a relatively short time interval.
  2. A competition involving a number of matches, each involving a subset of the competitors, with the overall tournament winner determined based on the combined results of these individual matches. These are common in those sports and games where each match must involve a small number of competitors: often precisely two, as in most team sports, racket sports and combat sports, many card games and board games, and many forms of competitive debating. Such tournaments allow large numbers to compete against each other in spite of the restriction on numbers in a single match.
Rostock Place in Mecklenburg-Vorpommern, Germany

Rostock is a city in the north German state Mecklenburg-Vorpommern. Rostock is on the Warnow river; the district of Warnemünde, 12 kilometres north of the city centre, is directly on the Baltic Sea coast. Rostock is the largest city in Mecklenburg-Vorpommern, as well as its only regiopolis.


Duke Valdemar died in the spring of 1312. He was succeeded as Duke by his son Eric II who had already been his father's coruler for several years. Valdemar was buried in the Schleswig Cathedral.

Marriage and Issue

In 1287 Duke Valdemar married Elisabeth of Saxe-Lauenburg, a daughter of John I, Duke of Saxony. This marriage produced the only legitimate son of Duke Valdemar:

In 1306 he married Anastasia of Schwerin, a daughter of Niklot I, Count of Schwerin.
