The Duchy of Oldenburg (German: Herzogtum Oldenburg) — named after its capital, the town of Oldenburg — was a state in the north-west of present-day Germany. Oldenburg survived from 1180 until 1810 when it was annexed by First French Empire. It was located near the mouth of the River Weser. When the main lineage of the House of Oldenburg Anthony Günther, Count of Oldenburg died out in 1667, it fell to the Danish Royal Family. Charles Frederick of the line of the Dukes of Holstein-Gottorp married Grand Duchess Anna Petrovna of Russia daughter of Peter the Great. Another, his first cousin, Frederick August I became Duke of Oldenburg in 1774. One of his brothers, Adolf Frederick became King of Sweden. Another brother, Prince Georg Ludwig of Holstein-Gottorp, was father of Peter I which became Grand Duke of Oldenburg in 1823. Subsequent Rulers of Oldenburg were all his descendants.[1] Its ruling family, the House of Oldenburg, also came to rule in Denmark, Norway, Sweden, Greece and Russia,[2] and the heirs of a junior line of the Greek branch are, through Prince Philip, Duke of Edinburgh, likely to inherit the thrones of the United Kingdom and the other Commonwealth realms after the death or abdication of Queen Elizabeth II.
History
The first known count of Oldenburg is Elimar I (d. 1108). Elimar's descendants appear as vassals, though sometimes rebellious ones, of the dukes of Saxony; but they attained the dignity of princes of the empire when the emperor Frederick I dismembered the Saxon duchy in 1180. At this time, the county of Delmenhorst formed part of the dominions of the counts of Oldenburg, but afterwards it was on several occasions separated from them to form an appanage for younger branches of the family. This was the case between 1262 and 1447, between 1463 and 1547, and between 1577 and 1617.[2]
During the early part of the 13th century the counts carried on a series of wars with independent, or semi-independent, Frisian princes to the north and west of the county, which resulted in a gradual expansion of the Oldenburgian territory. The Free Hanseatic City of Bremen and the bishop of Münster were also frequently at war with the counts of Oldenburg.[2]
In 1440, Christian succeeded his father Dietrich, called Fortunatus, as Count of Oldenburg. In 1448 Christian was elected king of Denmark as Christian I, partly based on his maternal descent from previous Danish kings. Although far away from the Danish borders, Oldenburg was now a Danish exclave. The control over the town was left to the king's brothers, who established a short reign of tyranny.[2]
In 1450 Christian became king of Norway and in 1457 king of Sweden; in 1460 he inherited the Duchy of Schleswig and the County of Holstein, an event of high importance for the future history of Oldenburg. In 1454 he handed over Oldenburg to his brother Gerhard (about 1430–99), a wild prince, who was constantly at war with the prince-bishop of Bremen and other neighbors. In 1483, Gerhard was compelled to abdicate in favor of his sons, and he died while on pilgrimage in Spain.[2]
Early in the 16th century Oldenburg was again enlarged at the expense of the Frisians. Lutheranism was introduced into the county by Anthony I (1505–73, r. from 1529), who also suppressed the monasteries; however, he remained loyal to Emperor Charles V during the Schmalkaldic War, and was able thus to increase his territories, obtaining Delmenhorst in 1547. One of Anthony's brothers, Christopher (about 1506–60), won some reputation as a soldier.[2]
Anthony's grandson, Anthony Günther (1583–1667), who succeeded in 1603, considered himself the wisest prince who had yet ruled Oldenburg. Jever had been acquired before he became count, but in 1624 he added Kniphausen and Varel to his lands, with which in 1647 Delmenhorst was finally united. By his neutrality during the Thirty Years' War and by donating valuable horses to the warlord, the Count of Tilly, Anthony Günther secured for his dominions an immunity from the terrible devastations to which nearly all the other states of Germany were exposed. He also obtained from the emperor the right to levy tolls on vessels passing along the Weser, a lucrative grant which soon formed a material addition to his resources. In 1607 he erected a Renaissance castle.[2] After the death of Anthony Günther, Oldenburg fell again under Danish authority.
In 1773 Christian VII of Denmark surrendered Oldenburg to Catherine the Great in exchange for her son and heir Paul's share in the condominial royal-ducal government of the Duchy of Holstein and his claims to the ducal share in the government of the Duchy of Schleswig; Oldenburg went to Frederick August, Administrator of the Prince-Bishopric of Lübeck, the representative of a younger branch of the family, and in 1777 the county was raised to the rank of a duchy. The duke's son William, who succeeded his father in 1785, was a man of weak intellect, and his cousin Peter, Administrator of the Prince-Bishopric of Lübeck, acted as regent and eventually, in 1823, inherited the throne, holding the Prince-Bishopric of Lübeck and Oldenburg in personal union.
By the German Mediatisation of 1803, Oldenburg acquired the Oldenburg Münsterland and the Prince-Bishopric of Lübeck. Between 1810 and 1814, Oldenburg was occupied by Napoleonic France. Its annexation into the French Empire, in 1810, was one of the causes for the diplomatic rift between former allies France and Russia, a dispute that would lead to war in 1812 and eventually to Napoleon's downfall.
Aftermath
In 1814 the Duchy acquired the Principality of Birkenfeld and became a grand duchy.[2]
In 1871 Oldenburg joined the German Empire,[2] and in 1918 it became a free state within the Weimar Republic.

In 1937 (with the Greater Hamburg Act), it lost the exclave districts of Eutin near the Baltic coast and Birkenfeld in southwestern Germany to Prussia and gained the City of Wilhelmshaven; however, this was a formality, as the Hitler régime had de facto abolished the federal states in 1934.
By the beginning of World War II in 1939, as a result of these territorial changes, Oldenburg had an area of 5,375 square kilometres (2,075 sq mi) and 580,000 inhabitants.
In 1946, after World War II, Oldenburg merged into the newly founded state of Lower Saxony forming, territorially unchanged, the administrative region (Verwaltungsbezirk) of Oldenburg. Region and State both became a part of West Germany in 1949. The administrative region was abolished in 1978 and merged with neighbouring governorates (Regierungsbezirke) into the new region of Weser-Ems, dissolved in 2004.
