The House of Welf is the older branch of the House of Este, a dynasty whose earliest known members lived in Lombardy in the late 9th/early 10th century, sometimes called Welf-Este. The first member was Welf IV; he inherited the property of the Elder House of Welf when his maternal uncle Welf III, Duke of Carinthia and Verona, the last male Welf of the Elder House, died in 1055. Welf IV was the son of Welf III's sister Kunigunde of Altdorf and her husband Albert Azzo II of Este, Margrave of Milan. In 1070, Welf IV became duke of Bavaria.

Welf V married Countess Matilda of Tuscany, who died childless and left him her possessions, including Tuscany, Ferrara, Modena, Mantua, and Reggio, which played a role in the Investiture controversy. Since the Welf dynasty sided with the Pope in this controversy, partisans of the Pope came to be known in Italy as Guelphs.

Bavaria and Saxony

Henry the Black, duke of Bavaria from 1120–1126, was the first of the three dukes of the Welf dynasty called Henry. His wife Wulfhild was the heiress of the house of Billung, possessing the territory around Lüneburg in Lower Saxony. Their son, Henry the Proud was the son-in-law and heir of Emperor Lothair of Supplinburg and became also duke of Saxony on Lothair's death. Lothair left his territory around Brunswick, inherited from his mother of the Brunonen family, to his daughter Gertrud. Her husband Henry the Proud became then the favoured candidate in the imperial election against Conrad III of the Hohenstaufen. But Henry lost the election, as the other princes feared his power and temperament, and was dispossessed of his duchies by Conrad III. Henry's brother Welf VI (1115–1191), Margrave of Tuscany, later left his Swabian territories around Ravensburg, the original possessions of the Elder House of Welf, to his nephew Emperor Frederick I and thus to the House of Hohenstaufen.

Henry the Lion recovered his father's two duchies, Saxony in 1142, Bavaria in 1156 and thus ruled vast parts of Germany. In 1168 he married Matilda (1156–1189), the daughter of Henry II of England and Eleanor of Aquitaine, and sister of Richard Lionheart, gaining ever more influence. His first cousin, Emperor Frederick I of the Hohenstaufen dynasty, tried to get along with him, but when Henry refused to assist him once more in an Italian war campaign, conflict became inevitable. Dispossessed of his duchies after the Battle of Legnano in 1176 by Emperor Frederick I and the other princes of the German Empire eager to claim parts of his vast territories, he was exiled to the court of his father-in-law Henry II in Normandy in 1180, but returned to Germany three years later. Henry made his peace with the Hohenstaufen Emperor in 1185, and returned to his much diminished lands around Brunswick without recovering his two duchies. Bavaria had been given to Otto I Wittelsbach, Duke of Bavaria, and the Duchy of Saxony was divided between the Archbishop of Cologne, the House of Ascania and others. Henry died at Brunswick in 1195.

Brunswick and Hanover

Henry's son Otto of Brunswick was elected King of the Romans and crowned Holy Roman Emperor Otto IV after years of further conflicts with the Hohenstaufen emperors. He incurred the wrath of Pope Innocent III and was excommunicated in 1215. Otto was forced to abdicate the imperial throne by the Hohenstaufen Frederick II.[2] He was the only Welf to become emperor of the Holy Roman Empire.

Henry the Lion's grandson Otto the Child became duke of a part of Saxony in 1235, the new Duchy of Brunswick-Lüneburg, and died there in 1252. The duchy was divided several times during the High Middle Ages amongst various lines of the House of Welf, but the rulers all continued to be styled as the "Duke of Brunswick-Lüneburg" in addition to "Prince of Lüneburg", "Prince of Wolfenbüttel", "Prince of Calenberg-Gottingen" or "Prince of Grubenhagen" etc. The subsequent history of the dukedom and its subordinate principalities was characterized by numerous divisions and reunifications. The subordinate states that were repeatedly created, and which had the legal status of principalities within the duchy (officially remaining an undivided imperial fief) were generally named after the residences of their rulers. The estates of the different dynastic lines could be inherited by a side line when a family died out. The individual subordinate principalities continued to exist until the end of the Holy Roman Empire in 1806. Following the Congress of Vienna in 1814/15, the territories became part of the Kingdom of Hanover and the Duchy of Brunswick.

Principality of Brunswick-Wolfenbüttel

In 1269 the Principality of Brunswick was formed following the first division of the Duchy of Brunswick-Lüneburg. In 1432, as a result of increasing tensions with the townsfolk of Brunswick, the Brunswick Line moved their residence to Wolfenbüttel Castle, thus the name Wolfenbüttel became the unofficial name of this principality. With Ivan VI of Russia the Brunswick line even had a short intermezzo on the Russian imperial throne in 1740. Not until 1754 was the residence moved back to Brunswick, into the new Brunswick Palace. In 1814 the principality became the Duchy of Brunswick, ruled by the senior branch of the House of Welf.

Principality of Calenberg – later Electorate of Brunswick-Lüneburg

In 1432 the estates gained by the Principality of Brunswick-Wolfenbüttel between the Prince Ernest II of Lüneburg, who chose Hanover as his residence. New territory was added in 1665, and in 1705 the Principality of Luneburg was taken over by the Hanoverians. In 1692 Duke Ernest Augustus from the Calenberg-Hanover Line acquired the right to be a prince-elector of the Holy Roman Empire as the Prince-Elector of Brunswick-Lüneburg. Colloquially the Electorate was known as the Electorate of Hanover. In 1814 it was succeeded by the Kingdom of Hanover.

British Succession

Religion-driven politics brought about Ernest Augustus' wife personal union from 1714 between the British crown and the Electorate of Hanover, which lasted until well after the end of the Napoleonic Wars more than a century later, through the dissolution of the Holy Roman Empire and the rise of a new successor kingdom. The British royal family became known as the House of Hanover.

Kingdom of Hanover

The "Electorate of Hanover" (the core duchy) was enlarged with the addition of other lands and became the elector of Hanover until the death of William IV in 1837. At that point, the crown of Hanover went to William's younger brother, Ernest Augustus, Duke of Cumberland and Teviotdale under the Salic law requiring the next male heir to inherit, whereas the British throne was inherited by an elder brother's only daughter, Queen Victoria. Her offspring belong to the House of Saxe-Coburg and Gotha: in 1917 the name was changed to the House of Windsor.

The Kingdom of Hanover was lost in 1866 by Ernest Augustus' son Austro-Prussian War, when it was annexed by Prussia after Austria's defeat, and became the Prussian province of Hanover. The Welfs went into exile at Gmunden, Austria, where they built Cumberland Castle.

Brunswick succession

The senior line of the dynasty had ruled the much smaller principality of Brunswick-Wolfenbüttel, created the sovereign Duchy of Brunswick in 1814. This line became extinct in 1884. Although the Duchy should have been inherited by the Duke of Cumberland, son of the last king of Hanover, Prussian suspicions of his loyalty led the duchy's throne to remain vacant until 1913, when the Duke of Cumberland's son, Ernst August, married the daughter of Kaiser Wilhelm II and was allowed to inherit it. His rule there was short-lived, as the monarchy came to an end following the First World War in 1918.

The Welf dynasty continues to exist. The last member sitting on a European throne was Princess Sophie of Greece and Denmark, sister of Prince Philip, Duke of Edinburgh. The House's head is Queen Frederica's nephew Ernst August, the third and present husband of Princess Caroline of Monaco.
