Henry the Lion'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. He was the only Welf to become Holy Roman Emperor. |alt=Shield divided per pale: a red field with two gold lions on the left, and a gold field with a blue lion surrounded by red hearts on the right. 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. The subordinate states had the legal status of principalities within the duchy, which remained as an undivided imperial
fief. Each state was generally named after the ruler's residence, e.g., the rulers of Brunswick-Wolfenbüttel originally lived in Wolfenbüttel. Whenever a branch of the family died out in the male line, the territory was given to another line, as the duchy remained enfeoffed to the family as a whole rather than its individual members. All members of the House of Welf, male or female, bore the title
Duke/Duchess of Brunswick-Lüneburg in addition to the style of the subordinate principality. By 1705, the subordinate principalities had taken their final form as the
Electorate of Hanover and the
Principality of Brunswick-Wolfenbüttel, and these would become the
Kingdom of Hanover and the
Duchy of Brunswick after the
Congress of Vienna in 1815.
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.

In 1432 the estates gained by the
Principality of Brunswick-Wolfenbüttel between the
Deister and
Leine split away as the
Principality of Calenberg. In 1495 it was expanded around
Göttingen and in 1584 went back to the Wolfenbüttel Line. In 1634, as a result of inheritance distributions, it went to the
House of Luneburg residing at
Celle Castle. In 1635 it was given to
George, younger brother of
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 placed Ernest Augustus's wife
Sophia of the Palatinate in the line of succession to the British crown by the
Act of Settlement 1701, written to ensure a Protestant succession to the thrones of Scotland and England at a time when anti-Catholic sentiment ran high in much of Northern Europe and Great Britain. Sophia died shortly before her first cousin once removed,
Anne, Queen of Great Britain, the last sovereign of the
House of Stuart. Sophia's son
George I succeeded Queen Anne and formed a
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. File:Coat of arms of Great Britain (1714–1801).svg|Coat of arms of the Hanoverian Kings of Great Britain (1714–1801) File:Bernard Lens King George I 1718 VA.jpg|

Kingdom of Hanover The "Electorate of Hanover" (the core duchy) was enlarged with the addition of other lands and became the
Kingdom of Hanover in 1814 at the
Congress of Vienna. During the first half of the nineteenth century, the Kingdom was ruled as
personal union by the
British crown from its creation under
George III of the United Kingdom, the last
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's son
George V of Hanover, Austria's ally during the
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. File:Coat of Arms of the Kingdom of Hanover.svg|Coat of arms of the

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.
Welf Dynasty Today The Welf dynasty continues to exist. The last member sitting on a European throne was
Frederica of Hanover, daughter of Ernest Augustus, the last Duke of Brunswick, was the Queen of Greece († 1981), mother of
Queen Sofia of Spain and King
Constantine II of Greece. Frederica's brother
Prince George William of Hanover married
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. File:Leineschloss Leine.jpg|The
