Question: Eric VI of Denmark was the son of the king who was the son of whom?
Context: Eric II the Memorable (Danish: "Erik II Emune" ) (  1090 – 18 September 1137) was king of Denmark between 1134 and 1137.  Eric was an illegitimate son of Eric I of Denmark, who ruled Denmark from 1095 to 1103.  Eric the Memorable rebelled against his uncle Niels of Denmark, and was declared king in 1134.  He punished his adversaries severely, and rewarded his supporters handsomely.  He was killed by a subject in 1137 and was promptly succeeded by his nephew Eric III of Denmark. Eric of Pomerania KG (1381 or 1382 – 24 September 1459) was King Eric (Eirik) III of Norway (1389–1442), King Eric VII of Denmark (1396–1439), and King Eric ("Ericus") of Sweden (1396–1439), in all three known mainly as "Erik af/av Pommern".  He was the first King of the Nordic Kalmar Union, succeeding his adoptive mother Margaret I of Denmark, and was also Duke Eric I of Pomerania. Eric V Klipping (1249 – November 22, 1286) was King of Denmark (1259–1286) and son of Christopher I.  Until 1264 he ruled under the auspices of his mother, the competent Queen Dowager Margaret Sambiria.  Between 1261 and 1262, Eric was a prisoner in Holstein following a military defeat.  Afterwards, he was brought up in Brandenburg. Canute VI (Danish: Knud Valdemarsøn ; 1163 – 12 November 1202) was King of Denmark (1182–1202).  Canute VI was the eldest son of King Valdemar I and Sophia of Polotsk. Princess Ingeborg Magnusdotter of Sweden, (b. 1277, Sweden – d. 5 April or 15 August 1319), was a Danish queen consort, daughter of king Magnus III of Sweden and wife of king Eric VI of Denmark. Bhuvanekabahu VI (Sapumal Kumaraya) (Sinhala:සපුමල් කුමාරයා, Tamil: செண்பகப் பெருமாள்) or Chempaha Perumal (died 1480) was by self admission an adopted son of Parakramabâhu VI whose principal achievement was the conquest of Jaffna Kingdom in the year 1447 or 1450.  He ruled the Kingdom for 17 years when he was apparently summoned to the south after the demise of his adopted father.  According to a primary source "Rajavaliya", he killed the grand son of Parakrama Bahu VI namely Vira Parakrama Bahu or Jaya Bahu (1468 – c. 1470) but Do Couto, however, who was well-informed, says after a few years' reign the king died and his half-witted son was put on the throne by his aunt, who two years later finding herself unable to rule sent for Sapumal Kumaraya from Jaffna. Olaf II Haakonsson (1370 – 23 August 1387) was King of Denmark as Olaf II (1376–1387) and King of Norway as Olaf IV (1380–1387).  Olaf was son of King Haakon VI of Norway and the grandson of King Magnus IV of Sweden.  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). Christian VI (30 November 1699 – 6 August 1746) was King of Denmark and Norway from 1730-46.  The eldest surviving son of King Frederick IV and Louise of Mecklenburg-Güstrow, he is considered one of Denmark's more anonymous kings, but he was a skilled politician, best known for his authoritarian regime.  He was the first king of the Oldenburg dynasty to refrain from entering in any war.  He was married to Sophia Magdalene of Brandenburg-Kulmbach and was the father of Frederick V.  His chosen motto was "deo et populo" (for God and the people). Eric VI "Menved" (1274 – 13 November 1319) was King of Denmark (1286–1319) and a son of Eric V and Agnes of Brandenburg. The dual monarchy of England and France existed during the latter phase of the Hundred Years' War when Charles VII of France and Henry VI of England disputed the succession to the throne of France.  It commenced on 21 October 1422 upon the death of King Charles VI of France, who had signed the Treaty of Troyes which gave the French crown to his son-in-law Henry V of England and Henry's heirs.  It excluded King Charles's son, the Dauphin Charles, who by right of primogeniture was the heir to the Kingdom of France.  Although the Treaty was ratified by the Estates-General of France, the act was a contravention of the French law of succession which decreed that the French crown could not be alienated.  Henry VI, son of Henry V, became king of both England and France and was recognized only by the English and Burgundians until 1435 as King Henry II of France.  He was crowned King of France on 16 December 1431.
