Heinrich (the Lion) Herzog von Sachsen ^{2275,2276,2277,2278}

  Notater:

Henry the Lion (German: Heinrich der Löwe; 1129/1131 - 6 August 1195) was a member of the Welf dynasty and Duke of Saxony, as Henry III, from 1142, and Duke of Bavaria, as Henry XII, from 1156, the duchies of which he held until 1180.

He was one of the most powerful German princes of his time, until the rival Hohenstaufen dynasty succeeded in isolating him and eventually deprived him of his duchies of Bavaria and Saxony during the reign of his cousin Frederick I Barbarossa and of Frederick's son and successor Henry VI.

At the height of his reign, Henry ruled over a vast territory stretching from the coast of the North and Baltic Seas to the Alps, and from Westphalia to Pomerania. Henry achieved this great power in part by his political and military acumen and in part through the legacies of his four grandparents.

Heinrich blev gift med Clementia Zähringen. (Clementia Zähringen døde før 1167.)

Heinrich blev derefter gift med Matilda of England den 1 Feb. 1168 i Minden, Nordrhein-Westfalen, Germany. (Matilda of England blev født ansl 15 Jun. 1156 i Windsor Castle, Windsor, Berkshire, England, døde den 28 Jun. 1189 i Braunschweig, Germany og blev begravet i Braunschweig Cathedral, Germany.)

Heinrich havde et forhold til Ida von Bliescastel, datter af Gottfried I Graf von Blieskastel og N.N. von Lorraine.
