Henry the Lion came from the
Welf Dynasty. Since the 1120s, there arose more documents in the history of this family, where there were different spellings. This meant the Welfs were the first noble family in the kingdom that we know the history of. The household records in the
Genealogia Welforum, in which the Saxon Welf Origins and the
Historia Welforum are found, show a link before the
Carolingians, and have a possible etymology of the name Welf, which may come from the Latin word catulus (Welpe in German). The ancestors of the Welfs begin in the eighth century at the time of the Carolingians. The rise of the family came completely from advantageous marriages. The Welf Judith was the second wife of Emperor
Louis the Pious, and brought the earliest influence of the Welfs to the history of the
Frankish Kingdom. Her sister,
Hemma, was married to Judith's stepson King Ludwig the German. This second marriage into the Carolingian royal family secured the rise of the Welfs in the Royal Circle. The fall of the Frankish Kingdom offered an opportunity for the family of the
Kings of Burgundy in 1032. After the death of Welf III in 1055 without an heir, the dynasty was thrown into an existential crisis. His sister, Cuniza, married the
Margrave Azzo II of Este, changing the future of the dynasty. The grandfather of Henry the Lion, the Bavarian Duke
Henry the Black, married
Wulfhild, the eldest daughter of the Saxon Duke
Magnus Billung and
Sophia, the daughter of the Hungarian King. Large tracts of land around
Luneberg the center of power and the burial place of the
House of Billung, now went to the Welfs. In 1123 a relative of the family,
Bishop Conrad of Constance, was put forward for canonisation, and raised the reputation of the family. The Welf
Judith, daughter of Henry the Black, married the Hohenstaufen Duke
Frederick II, the father of Frederick Barbarossa. The candidacy of Frederick II as the successor to the ore rich lands of the late, childless
Henry V stayed unsponsored. Instead, the Saxon duke
Lothar III was preferred. The usual sponsors of Henry the Black were split between him and Duke Lothar. Some of these sponsors were won over by Lothar marrying his only daughter
Gertrude to Henry's son, Henry the Proud. Gertrude’s mother was
Richenza, heiress of the Saxon territories of
Northeim and the properties of the
Brunones, counts of
Brunswick. From this union came Henry the Lion. He was born in Ravensburg. From the Steterburger Chronik, he must have been born around 1129/1130. His baptism was around 1135/36, but this seems a long time to wait for a baptism. It is possible that the copyist made a transcription error, so Henry's birth could have been in 1133/35. Soon after, Henry the Proud gained a conglomeration of duchies, close to the size of a kingdom. At the end of the reign of his father in law Lothar, he ruled over the duchies of Bavaria and Saxony, and over the
March of Tuscany in the Mathilda Guter, specifically the extensive lands in
Swabia, Bavaria, Saxony and
Italy. Henry's father died in 1139, aged 32, when Henry was still a child. King
Conrad III had dispossessed Henry the Proud of his duchies in 1138 and 1139, handing Saxony to
Albert the Bear and Bavaria to
Leopold of Austria. This was because Henry the Proud had been his rival for the Crown in 1138. ==Rule==
