Absalon first appears in Saxo Grammaticus's contemporary chronicle Gesta Danorum at the end of the civil war, at the brokering of the peace agreement between Sweyn III and Valdemar at St. Alban's Priory, Odense.

The pirates had raided the Danish coasts during the civil war of Sweyn III, Canute V, and Valdemar, to the point where at the accession of Valdemar one-third of Denmark lay wasted and depopulated.

However, during the schism between Pope Alexander III and Antipope Victor IV, Absalon stayed loyal to Valdemar even as he joined the Holy Roman Emperor Frederick Barberossa in supporting Victor IV.

King Sweyn III is killed and Valdemar I restores the country.

** King Valdemar III of Denmark ( b. 1314 )

Abroad, Frederick intervened in the Danish civil war between Svend III and Valdemar I of Denmark and began negotiations with the Eastern Roman Emperor, Manuel I Comnenus.

** Valdemar III of Denmark ( d. 1364 )

Initially named Boguslaw, he was son to the only surviving granddaughter of Valdemar IV of Denmark and also a descendant of Magnus III of Sweden and Haakon V of Norway.

George's siblings were Frederick ( who succeeded their father as King of Denmark ), Alexandra ( who became queen consort of Edward VII of the United Kingdom and the mother of King George V ), Dagmar ( who, as Empress Maria Feodorovna, was consort of Alexander III of Russia and the mother of Tsar Nicholas II ), Thyra ( who married Prince Ernest Augustus, 3rd Duke of Cumberland and Teviotdale ) and Valdemar.

Adolphus III ( d. 1225 ), his successor, received Dithmarschen in fee from the emperor Frederick I, but in 1203 the fortunes of war compelled him to surrender Holstein to Valdemar II of Denmark who mandated Albert of Orlamünde, the cession being confirmed in a Golden bull by the emperor Frederick II in 1214 and the pope in 1217, thus provoking the nobles in Holstein.

Valdemar was released from captivity in 1226 and appealed to Pope Honorius III to have his oath repealed, a request the Pope granted.

On the death of King Valdemar's descendant Eric VI of Denmark in 1319, Christopher II of Denmark attempted to seize the Duchy of Schleswig, the heir of which Duke Valdemar V ( as of 1325 ) was a minor ; but Valdemar's guardian and uncle, Gerhard III, Count of Holstein-Rendsburg ( 1304 – 1340 ), surnamed the Great and a notable warrior, drove back the Danes and, Christopher having been expelled, succeeded in procuring the election of Duke Valdemar to the Danish throne ( as Valdemar III as of 1326 ), while Gerhard himself obtained the Duchy of Schleswig.

King Valdemar III was regarded as a usurper by most Danish nobles as he had been forced by the Schleswig-Holstein nobility to sign the Constitutio Valdemaria ( June 7, 1326 ) promising that The Duchy of Schleswig and the Kingdom of Denmark must never be united under the same ruler.

In 1330, Christopher II was restored to his throne and Valdemar III of Denmark abdicated his untenable kingship and returned to his former position as Duke of Schleswig which he held as Valdemar V of Schleswig.

Southern parts of Schleswig had been mortgaged to several German nobles by Duke Henry I, Duke of Schleswig ( d. 1375, a son of the former king Valdemar III of Denmark ), the last duke of that line.

In 1386, Queen Margaret I of Denmark, younger daughter of Valdemar IV of Denmark and Helvig of Schleswig, granted Schleswig as a hereditary fief under the Danish crown to Count Gerhard VI of Holstein-Rendsburg, grandson of Gerhard III, provided that he swore allegiance to her son King Oluf, although Schleswig actually still was held autonomously by the Count of Holstein-Rendsburg.

After this decision, both Knud V and Valdemar Knudsson ( son of Knud Lavard, the enemy of his own father Magnus ) rebelled against Sweyn III, who was expelled in 1154: Knud V and Valdemar became co-kings of Denmark.

On 15 August 1193, he married Ingeborg ( 1175 – 1236 ), daughter of King Valdemar I of Denmark ( ruled 1157 – 82 ).

Due to pressure from the Pope and from Ingeborg's brother, King Valdemar II of Denmark ( ruled 1202 – 41 ), Philip finally took Isambour back as his Queen in 1213.

Eventually, Valdemar the Great ( 1131 – 82 ), gained control of the kingdom, stabilizing it and reorganizing the administration.

King Valdemar and Absalon ( ca 1128 – 1201 ), the bishop of Roskilde, rebuilt the country.

Saxo Grammaticus ( c. 1150 – 1220 ) also known as Saxo cognomine Longus was a Danish historian, thought to have been a secular clerk or secretary to Absalon, Archbishop of Lund, foremost advisor to Valdemar I of Denmark.

The brothers and sisters were Jørgine Caroline ( 1854 – 1879 ), Mathilde Sophie ( born 1856 ), Karen Marie ( 1857 – 1876 ), Jørgen Peter ( born 1859 ) emigrated to Australia, Johan Sophus ( 1861 – 1942 ) emigrated to USA, Christian Albert ( born 1863 ) emigrated to USA, Carl August ( 1865 – 1931 ), Anders Jacob ( born 1867 ) emigrated to USA, Helene Christine Louise ( born 1869 ) emigrated to USA, Valdemar Emil ( 1871 – 1965 ), Julie Christine ( born 1872 ), Anna Dusine ( 8 January to 2 April 1875 ). All the children bore the surname Nielsen despite regulations by the Ministry of Church Affairs.

Duke Valdemar V of Slesvig's son, Henry, was in 1364 nominally entfeoffed with the Duchy, although he never reached to regain more than the northernmost parts as he couldn't raise the necessary funds to repay the loans.

Valdemar died in 1364.

He was the foremost politician and churchfather of Denmark in the second half of the 12th century, and was the closest advisor of King Valdemar I of Denmark.

He grew up at the castle of his father, and was brought up alongside his older brother Esbern Snare and the young prince Valdemar, who later became King Valdemar I of Denmark.

He was a guest at following Roskilde banquet given in 1157 by Sweyn to his rivals Canute V and Valdemar.

Absalon probably did not take part in the following battle of Grathe Heath in 1157, in which Sweyn was defeated and slain and led to Valdemar ascending the Danish throne.

On Good Friday 1158, bishop Asser of Roskilde died, and Absalon was eventually elected bishop of Roskilde on Zealand with the help of Valdemar, as the king's reward for the Hvide family support.

Absalon was a close counsellor of Valdemar, and chief promotor of the Danish crusades against the Wends.

It was contrary to Absalon's advice and warnings that Valdemar I rendered fealty to the emperor Frederick Barbarossa at Dole in 1162.

When Valdemar returned to Denmark, he was convinced into strengthening the Danevirke fortifications at the German border, with the support of Absalon.

Furthermore he claims that Bishop Theoderich, already co-initiator of the Livonian Brothers of the Sword in Livonia, had the idea of starting a similar order in Estonia ; and that he was the original instigator of the inquiry from Bishop Albert of Buxhoeveden to King Valdemar II in 1218, that set the whole Danish participation in the Baltic crusades in motion.

Since King Valdemar II of Denmark was married to the Portuguese princess, Berengária of Portugal, it is not unthinkable that the origin of the story, if not the flag, was the Spanish tale or a similar tale, which again might have been inspired by an even older legend.

Duddell didn't further develop his invention, but in 1902 Danish physicists Valdemar Poulsen and P. O. Pederson were able to increase the frequency produced into the radio range, inventing the Poulsen arc radio transmitter, the first continuous wave radio transmitter, which was used through the 1920s.

Magnetic tape was invented for recording sound by Fritz Pfleumer in 1928 in Germany, based on the invention of magnetic wire recording by Valdemar Poulsen in 1898.

Otto ’ s cause was further strengthened by the support of the Danish king, Valdemar II.

After his death, his canonization was demanded by King Valdemar IV of Denmark and promised by his successor, Pope Gregory XI, as early as 1375, but this did not take place owing to the disorders of the time.

Valdemar himself was saved only by the courageous actions of a German knight who carried Valdemar to safety on his horse.

After one of them was assassinated in 1340, Christopher's son Valdemar was chosen as king, and gradually began to recover the pawned territories, which was completed in 1360.

Margaret, the queen mother, who was the oldest daughter of King Valdemar IV of Denmark, succeeded in uniting Norway with Denmark, Norway and Sweden under the Kalmar Union.

Haakon VII ( Prince Carl of Denmark and Iceland, born Christian Frederik Carl Georg Valdemar Axel ) ( 3 August 1872 21 September 1957 ), known as Prince Carl of Denmark until 1905, was the first king of Norway after the 1905 dissolution of the personal union with Sweden.
