This article is about the high noble house of Oldenburg. For the lower noble family of the same name, see Oldenburg (Mecklenburg noble family).
The House of Oldenburg is one of the most important families of the ruling European high nobility. It is based on an old northern German dynasty of princes whose origins lie in the Osnabrück Nordland. It was first attested with Egilmar I in 1091. The eponymous castle of Aldenburg (Oldenburg) lay on the Hunte, was first mentioned in 1108 and served the Counts of Oldenburg as their residence from the middle of the 12th century.
In 1448 an Oldenburg count was elected to the Danish royal throne and ceded the county to his younger brother. The Danish line, which has ruled uninterruptedly ever since, later branched out many times, ruling at the same time in the Duchy of Schleswig and in the County of Holstein, at times also in Sweden and to this day in Norway. In 1667 the County of Oldenburg - after the extinction of the younger line - fell to it again, then in 1762 the Russian Tsar's throne and in 1863 the Crown of Greece. All branches form the entire house of Oldenburg.
The Grand Dukes of Oldenburg, who reigned until 1918, as well as the Russian tsars from the House of Romanov-Holstein-Gottorp and the Swedish kings until 1818 belong genealogically to the House of Schleswig-Holstein-Gottorf, also a branch of the Danish line of the entire House of Oldenburg. The Grand Ducal line of Oldenburg is the oldest surviving line and provides the head of the house. The royal houses of Denmark and Norway, which still reign today, belong genealogically to the Schleswig-Holstein-Sonderburg-Glücksburg branch, as do the former Greek royal house and Prince Philip, husband of the British Queen Elizabeth II, and his descendants.
History
The Oldenburg dynasty gained European importance when Christian I, the eldest son of Count Dietrich von Oldenburg († 1440), was elected King of Denmark in 1448 and King of Sweden and Norway in 1457. He founded the line that still reigns in Denmark and Norway today. His younger brother Gerhard IV. gen. Gerd the Brave (abged. 1482) (c. 1430-1500) continued the countly line ruling in the county of Oldenburg, which became extinct with the death of the count Anton Günther, who was outstanding in land history, in 1667. Anton, the illegitimate son of Anton Günther, became the founder of the semi-sovereign house of Aldenburg-Bentinck, while the county of Oldenburg fell to the older, royal Danish line. From this branched off, among others, the lines Schleswig-Holstein-Gottorf (also Holstein-Gottorp, from 1762 Russian tsarist house Romanow-Holstein-Gottorp) and Schleswig-Holstein-Sonderburg.

The Sonderburg line disintegrated into numerous branches: The Augustenburg branch of Schleswig-Holstein-Sonderburg-Augustenburg became extinct in 1931, whereas the younger Glücksburg line - Holstein-Sonderburg-Glücksburg, actually the line of the Dukes of Beck - came to the Danish throne with Christian IX in 1863 and holds it to this day. King Christian IX's second son became King of Greece as George I in 1863. His descendants ruled there until 1967.
Charles, grandson of Christian IX, became King of Norway as Håkon VII in 1905, where the Oldenburgs also provide the king to this day. The Greek branch provides with Charles, son of Philip Mountbatten, Duke of Edinburgh (born as Prince Philippos Andreou of Greece and Denmark), the British heir to the throne.
Even before the Glücksburg line received the Danish kingship, the older line of Schleswig-Holstein-Gottorp had attained the Russian Tsarist throne with Karl Peter Ulrich as Peter III. His descendants ruled Russia under the name Romanov-Holstein-Gottorp until 1917.
In 1751, Adolf Friedrich, a scion of the Gottorp line, attained the crown of Sweden and became the founder of the Swedish royal line, which held the throne until 1818, when it passed by adoption to the House of Bernadotte. With Frederick August of Holstein-Gottorp (1711-1786), Prince-Bishop of Lübeck, a brother of Adolf Frederick of Sweden received the county of Oldenburg in the Treaty of Tsarskoe Selo in 1773 and was elevated to duke in 1776. From him descended the Grand Dukes (since 1815) of Oldenburg (younger line Holstein-Gottorp), who ruled until 1918.
