Brunswick-Lüneburg in the context of "Prince-Elector Ernest Augustus"

The House of Hanover (German: Haus Hannover German pronunciation: [haʊ̯s haˈnoːfɐ]) is a German royal house with roots tracing back to the 17th century. Its members, known as Hanoverians, ruled Hanover, Great Britain, Ireland, and the British Empire at various times during the 17th to 20th centuries. Originating as a cadet branch of the House of Welf (also "Guelf" or "Guelph") in 1635, also known then as the House of Brunswick-Lüneburg, the Hanoverians ascended to prominence with Hanover's elevation to an Electorate of the Holy Roman Empire in 1692. In 1714 George I, prince-elector of Hanover and a descendant of King James VI and I, assumed the throne of Great Britain and Ireland, marking the beginning of Hanoverian rule over the British Empire. At the end of this line, Queen Victoria's death in 1901, the throne of the United Kingdom passed to her eldest son Edward VII, a member of the House of Saxe-Coburg and Gotha, through his father Albert, Prince Consort. The last reigning members of the House of Hanover lost the Duchy of Brunswick in 1918 when Germany became a republic and abolished royalty and nobility.

The formal name of the house was the "House of Brunswick-Lüneburg, Hanover line". The senior line of Brunswick-Lüneburg, which ruled Brunswick-Wolfenbüttel, became extinct in 1884. The House of Hanover is now the only surviving branch of the House of Welf, which is the senior branch of the House of Este. The current head of the House of Hanover is Ernst August, Prince of Hanover.

Elisabeth Christine of Brunswick-Wolfenbüttel (28 August 1691 – 21 December 1750) was Princess of Brunswick-Wolfenbuttel, Holy Roman Empress, German Queen, Queen of Bohemia and Hungary; and Archduchess of Austria, etc. by her marriage to Charles VI, Holy Roman Emperor. She was renowned for her delicate beauty and also for being the mother of Empress Maria Theresa and grandmother of Joseph II, Holy Roman Emperor, Leopold II, Holy Roman Emperor, Maria Carolina of Austria and Marie Antoinette of France. She was the longest serving Holy Roman Empress.

Conrad Buno (c. 1613–1671), was a German copperplate engraver, cartographer and publisher at the court of Wolfenbüttel (Guelpherbytum) and brother of Johann Buno (1617–1697), the theologian and pedagogue from Lüneburg.

Conrad Buno prepared a set of maps for the 1641 Brunswick-Lüneburg edition of Philipp Cluver's famous Introductio in Universam Geographicam, an atlas with maps of Africa, America, Asia and the World, and text written by Johann Buno.

Otto I of Brunswick-Lüneburg (about 1204 – 9 June 1252), a member of the House of Welf, was the first duke of Brunswick-Lüneburg from 1235 until his death. He is called Otto the Child to distinguish him from his uncle, Emperor Otto IV.

The County of Brunswick was a county in the medieval Duchy of Saxony. It existed from about the 9th century until 1235, when it was raised to a duchy, the Duchy of Brunswick-Lüneburg.

The county developed out of the possessions of the Brunonen dynasty centered on the town of Brunswick and was enlarged by the inheritances of Henry the Fat of Northeim around Northeim and Göttingen and a part of the Billung inheritance around Lüneburg, which fell to the House of Welf in 1106. When the Duchy of Saxony was reorganized in 1180, the county became de facto independent from the Duchy, since the new Ascanian dukes could not establish control over it. In 1203, the three sons of Duke Henry the Lion divided the county among themselves; Henry received the western part including Hannover and Göttingen, William received the area around Lüneburg, and King Otto IV the area around Braunschweig. The independence of Brunswick was recognized when it was raised to the Duchy of Brunswick-Lüneburg in 1235, which would exist until 1918.

William (4 July 1535 – 20 August 1592), called William the Younger (German: Wilhelm der Jüngere), was Duke of Brunswick-Lüneburg and Prince of Lüneburg from 1559 until his death. Until 1569, he ruled together with his brother, Henry of Dannenberg.
