The present senior member of the House of Oldenburg and the House of Glücksburg and traditional heir to the family's ancestral lands, including Glücksburg itself, is Friedrich Ferdinand, Prince of Schleswig-Holstein (born 1985), who heads the foundation that owns the family's ancestral seat, [[Glücksburg Castle]].

[[File:Schloss-Glücksburg-Luftaufnahme-0073-msu-2020-.jpg|thumb|[[Glücksburg Castle]], with the [[Flensburg Firth]] (separating Denmark and Germany) in the background]]

== Etymology ==
"House of Glücksburg" is the shortened form of "House of Schleswig-Holstein-Sonderburg-Glücksburg"{{Emdash}}a collateral branch of the [[House of Oldenburg]]. The house derives its name from two regions and two towns on the [[Jutland]] Peninsula.

The two regions of [[Schleswig]] and [[Holstein]] are divided by the [[Eider River]]. While Schleswig for centuries constituted the southernmost region of Denmark, [[Duchy of Holstein|Holstein]] historically has been the northernmost area within the [[Holy Roman Empire]]. The northern border of Holstein along the [[Eider (river)|Eider]] had already formed the northern border of [[Francia]] and the [[Carolingian Empire]], after Emperor [[Charlemagne]] upon the [[Saxon Wars]] reached an agreement with King [[Hemming of Denmark]] in 811. The lands of Schleswig beyond the river remained a fief of the Danish Crown, while Holstein became an integral part of [[East Francia]], the [[Kingdom of Germany]] and the [[Holy Roman Empire]]. Even earlier, the [[Eider (river)|Eider]] had already been the border river between [[Saxons]] and [[Polabian Slavs]] to the south, and Danes and [[North Frisians]] to the north. This is evidenced in the largely Slavic-derived [[toponomy]] in Eastern Holstein, as opposed to the many Danish-derived place names in Schleswig including Southern Schleswig. Since the [[1920 Schleswig plebiscites]], Schleswig has been divided between Denmark ([[Northern Schleswig]]), and Germany ([[Southern Schleswig]]).

The town of [[Sønderborg]]{{Emdash}}the German name of which is "Sonderburg"{{Emdash}}is located on the northern shores of the [[Flensburg Firth]] in Denmark (Northern Schleswig), while [[Glücksburg (Ostsee)]] lies on the southern shores of the firth in Germany (Southern Schleswig). The "Ostsee" suffix means "Baltic Sea" (''East Sea'').

Since [[Glücksburg Castle]] is the ancestral seat of the house, the house is mostly shortened to just "House of Glücksburg". It is also spelled "House of Glücksborg" (the name of Glücksburg in the local [[Low German]] dialect) or "House of Lyksborg" (the [[Danish language|Danish]] name of Glücksburg).

The literal translation of "Glücksburg" is "Luck's Castle" (Glück = luck; Burg = castle). Glücksburg is officially bilingual and since 2016, there are German/Danish city limit signs in the town.

==History==
[[File:2 rigdalers Denmark 1863.png|thumb|left|250px|2 [[Danish rigsdaler|rigsdaler]] - death of Frederik VII and accession of [[Christian IX of Denmark|Christian IX]] marking the transfer of the throne to the Glucksburg branch of the [[House of Oldenburg]]<ref>Year: 1863; Quantity released: 101,000 coin; Weight: 28.893 gram; Composition: Silver 87.5%; Diameter: 39.5 mm - https://en.numista.com/catalogue/pieces23580.html</ref>]]
Glücksburg is a small coastal town on the German southern side of the [[Flensburg Firth|fjord of Flensburg]] that divides Germany from Denmark.<ref name="Huberty"/> In 1460, Glücksburg came, as part of the conjoined Dano-German duchies of [[Schleswig-Holstein|Schleswig and Holstein]], to Count Christian of [[County of Oldenburg|Oldenburg]] whom, in 1448, the [[Denmark|Danes]] had elected their king as [[Christian I of Denmark|Christian I]], the [[Norway|Norwegians]] likewise taking him as their hereditary king in 1450.<ref name="Huberty"/>

In 1564, Christian I's great-grandson, King [[Frederick II of Denmark|Frederick II]], in re-distributing [[Partitioned-off duke|Schleswig and Holstein's fiefs]], retained some lands for his own senior royal line while allocating Glücksburg to his brother Duke [[John, Duke of Schleswig-Holstein-Sonderburg|John the Younger]] (1545–1622), along with [[Sønderborg]], in [[appanage]].<ref name="Huberty"/> John's heirs further sub-divided their share and created, among other branches, a line of [[Schleswig-Holstein-Sonderburg-Beck|Schleswig-Holstein-Sonderburg]] dukes at Beck (an estate near [[Bishopric of Minden|Minden]] bought by the family in 1605), who remained [[vassal]]s of Denmark's kings.<ref name="Huberty"/>

By 1825, the castle of Glücksburg had returned to the Danish crown (from another [[Schleswig-Holstein-Sonderburg-Glücksburg (elder line)|ducal branch called Glücksburg]], extinct in 1779) and was given that year by King [[Frederick VI of Denmark|Frederick VI]], along with a new ducal title, to his kinsman [[Friedrich Wilhelm, Duke of Schleswig-Holstein-Sonderburg-Glücksburg|Frederick of Schleswig-Holstein-Sonderburg-Beck]].<ref name=ggh>Gothaisches Genealogisches Handbuch der Fürstlchen Häuser, Band I. Verlag des Deutschen Adelsarchivs. Marburg. 2015. p. 140 (German). {{ISBN|978-3-9817243-0-1}}.</ref> Frederick suffixed the [[territorial designation]] to the ducal title he already held, in lieu of "Beck" (an estate the family had, in fact, sold in 1745).<ref name="Huberty"/> Thus emerged the extant ''Dukes of Schleswig-Holstein-Sonderburg-Glücksburg''.

The Danish line of Oldenburg kings died out in 1863, and the elder line of the [[Schleswig-Holstein-Sonderburg|Schleswig-Holstein]] family became extinct with the death of the last [[House of Schleswig-Holstein-Sonderburg-Augustenburg|Augustenburg]] [[Albert, Duke of Schleswig-Holstein|duke]] in 1931. Thereafter, the House of Glücksburg became the senior surviving line of the House of Oldenburg. Another [[cadet (genealogy)|cadet]] line of Oldenburgs, the [[Duke of Holstein-Gottorp|Dukes of Holstein-Gottorp]], consisted of two branches which held onto sovereignty into the 20th century. But members of the Romanov line were executed in or exiled from their [[Russian Empire]] in 1917, while the [[Grand Duchy of Oldenburg]] was abolished in 1918, although its [[non-dynastic|dynastic]] line survives.<ref name="Huberty"/>

Neither the Dukes of Beck nor of Glücksburg had been sovereign rulers; they held their lands in [[fief]] from the ruling Dukes of Schleswig and Holstein, i.e. the Kings of Denmark and (until 1773) the Dukes of [[Holstein-Gottorp]].

Prince Christian of Schleswig-Holstein-Sonderburg-Glücksburg, the fourth son of [[Friedrich Wilhelm, Duke of Schleswig-Holstein-Sonderburg-Glücksburg|Duke Friedrich of Glücksburg]], was recognized in the [[London Protocol (1852)|London Protocol of 1852]] as successor to the childless King [[Frederick VII of Denmark]]. He became King of Denmark as [[Christian IX of Denmark|Christian IX]] on 15 November 1863.<ref name="Huberty"/>

Prince Vilhelm, the second son of Crown Prince Christian and Crown Princess Luise, was elected [[King of the Hellenes]] on 30 March 1863, succeeding the ousted Wittelsbach [[Otto of Greece]] and reigning under the name [[George I of Greece|George I]].

Prince Carl, the second son of [[Frederick VIII of Denmark]], Christian IX's eldest son, became King of Norway on 18 November 1905 as [[Haakon VII]].

Christian IX's daughters, [[Alexandra of Denmark|Alexandra]] and [[Maria Feodorovna (Dagmar of Denmark)|Dagmar]] (as ''Maria Feodorovna'') became the consorts of, respectively, King [[Edward VII|Edward VII of the United Kingdom]] and Emperor [[Alexander III of Russia]]. As a result, by 1914 descendants of King Christian IX held the crowns of several European [[realm]]s, and he became known as the "[[Father-in-law of Europe]]".

Christian IX's older brother inherited formal headship of the family as [[Karl, Duke of Schleswig-Holstein-Sonderburg-Glücksburg]], followed by their brother [[Friedrich, Duke of Schleswig-Holstein-Sonderburg-Glücksburg]]. It is his descendants who now represent the senior line of the Schleswig-Holstein branch of the House of Oldenburg, with [[Friedrich Ferdinand, Prince of Schleswig-Holstein]], as its current head.

The Hellenic constitutional monarchy was usurped in a ''[[coup d'état]]'' by a [[Greek junta|military junta]] in 1967 and the royal family fled into exile. The monarchy was abolished in 1973.
