Margaret I of Denmark
Margaret I (15 March 1353 – 28 October 1412) was queen consort of Norway (1363–1380) and Sweden (1363–1364) and later ruler in her own right of Denmark, Norway and Sweden, from which later period there are ambiguities regarding her specific titles.
She was the founder of the Kalmar Union, which spanned Scandinavia for over a century.
Margaret was known as a wise, energetic and capable leader, who governed with "farsighted tact and caution," earning the nickname "Semiramis of the North".
She was derisively called "King Breechless", one of several mean nicknames invented by her rival Albert of Mecklenburg, but was also known by her subjects as "the Lady King", which became widely used in recognition of her capabilities.
Knut Gjerset calls her "the first great ruling queen in European history."
The youngest daughter of King Valdemar IV of Denmark, Margaret was born at the Søborg Castle.
She was a practical, patient administrator and diplomat, albeit one of high aspirations and a strong will, who intended to unite Scandinavia forever into one single entity with the strength to resist and compete against the might of the Hanseatic League.
She died childless, having survived her only son, Olaf II.
Margaret was ultimately succeeded by a string of more or less competent monarchs, after her efforts to raise and educate her heir Eric of Pomerania and his bride Philippa of England.
Philippa in particular was an excellent pupil. "
Although Eric came of age in 1401, Margaret continued for the remaining 11 years of her life to be sole ruler in all but name.
[Her] second regency marked the beginning of a Dano-Norwegian Union which was to last for more than four centuries."
Ultimately, the Union into which she put so much effort and hope gradually disintegrated.
Some Norwegian and Swedish historians have criticized Margaret for favouring Denmark and being too autocratic, though she is generally thought to have been highly regarded in Norway and respected in Denmark and Sweden.
She was painted in a negative light in contemporary religious chronicles, as she had no qualms suppressing the Church to promote royal power.
Margaret is known in Denmark as "Margrethe I" to distinguish her from the current queen, who chose to be known as Margrethe II in recognition of her predecessor.
Theodred II (Bishop of Elmham)
Theodred II was a medieval Bishop of Elmham.
The date of Theodred's consecration unknown, but the date of his death was sometime between 995 and 997.
Olaf (II) Haraldsen
Olaf Haraldsen( died) was a Danish anti-king who ruled Scania for a few years from 1139.
He never won control over the rest of Denmark, and he is not included in the list of Danish monarchs used by the Danish monarchy or" Den Store Danske Encyklopædi".
He is sometimes called" Olaf II" even though there was a later Olaf II of Denmark.
He was the son of Harald Kesja and thus nephew of King Eric II of Denmark.
He seems to have been the only who escaped Eric II's murder of Harald and his sons in 1135.
After trying in vain to regain his heritage, Olaf proclaimed himself king in Scania in 1139, fighting his cousin King Eric III of Denmark.
The civil war mostly consisted of alternating raids, during which Olaf killed Bishop Rike of Roskilde, an act that saw him excommunicated by the Pope.
He was at last defeated by Eric III and was killed in a battle in Middle Scania around 1143.
Harald Skrænk, the leader of a peasant rebellion in Scania about 1182, is said to have been Olaf's illegitimate son, but their connection is unsure.

His mother was Queen Margaret I of Denmark which made him the grandson of King Valdemar IV of Denmark.
In addition to his claim on the thrones of Denmark and later Norway, he was in the direct succession line to the throne of Sweden (but for the interposition of Albert of Mecklenburg).
He became King of Denmark when only five years old and later also succeeded his father as King of Norway.
