A personal union is the combination of two or more states that have the same monarch while their boundaries, laws, and interests remain distinct. A real union, by contrast, would involve the constituent states being to some extent interlinked, such as by sharing some limited governmental institutions. In a federation and a unitary state, a central (federal) government spanning all member states exists, with the degree of self-governance distinguishing the two. The ruler in a personal union does not need to be a hereditary monarch.
Personal unions can arise for several reasons, ranging from coincidence (a woman who is already married to a king becomes queen regnant, and their child inherits the crown of both countries; the King of one country inherits the crown of another country) to virtual annexation (where a personal union sometimes was seen as a means of preventing uprisings). They can also be codified (i.e., the constitutions of the states clearly express that they shall share the same person as head of state) or non-codified, in which case they can easily be broken (e.g., by the death of the monarch when the two states have different succession laws).
The Commonwealth realms are independent states that share the same person as monarch.
Because presidents of republics are ordinarily chosen from within the citizens of the state in question, the concept of personal union has almost never crossed over from monarchies into republics, with the rare exception of the President of France being a co-prince of Andorra. In 1860 Marthinus Wessel Pretorius was simultaneously elected as the president of Transvaal and Orange Free State and he tried to unify the two countries but his mission failed and led to the Transvaal Civil War.
Even though France is now a republic with a president and not a monarchy, it has nevertheless been in personal union with the neighboring nominal monarchy (non-hereditary) of Andorra since 1278.
In 1102, after a period of succession crisis following the death of King Demetrius Zvonimir, the Kingdom of Croatia entered a union with the Kingdom of Hungary in 1102. The crown passed into the hands of the Árpád dynasty with the crowning of King Coloman of Hungary with the Croatian crown as "King of Croatia and Dalmatia" in Biograd. Institutions of separate Croatian statehood were maintained through the Sabor (an assembly of Croatian nobles) and the ban (viceroy). In addition, the Croatian nobles retained their lands and titles. Some of the terms of Coloman's coronation are summarized in Pacta Conventa by which the Croatian nobles agreed to recognise Coloman as king. Although it is not an authentic document from 1102 and is likely a forgery from the 14th century, the contents of the Pacta Conventa correspond to the political situation of that time in Croatia.
The precise terms of the union between the two realms became a matter of dispute in the 19th century. The nature of the relationship varied through time, Croatia retained a large degree of internal autonomy overall, while the real power rested in the hands of the local nobility. Modern Croatian and Hungarian historiographies mostly view the relations between the Kingdom of Croatia and Kingdom of Hungary from 1102 as a form of a personal union presided over by the King of Hungary, resembling the relationship of Scotland to England.
It is argued that the medieval Hungary and Croatia were (in terms of public international law) allied by means of personal union until the Battle of Mohács in 1526. On January 1, 1527, the Croatian nobles at Cetin unanimously elected Ferdinand, Archduke of Austria, as their king, and confirmed in Cetingrad Charter the succession to him and his heirs. However, officially the Hungarian-Croatian state existed until the beginning of the 20th century and the Treaty of Trianon.
After 1707, see Great Britain below.
Note: The point at issue in the War of the Spanish Succession was the fear that the succession to the Spanish throne dictated by Spanish law, which would devolve on Louis, le Grand Dauphin — already heir to the throne of France — would create a personal union that would upset the European balance of power; France had the most powerful military in Europe at the time, and Spain the largest empire.

The King Chungseon reigned as King of Goryeo in 1298 and 1308–1313 and King of Shenyang or Shen from 1307 (according to the History of Yuan) or 1308 (according to Goryeosa) to 1316. At that time, Goryeo had already become a vassal of Yuan and the imperial family of Yuan and the royal family of Goryeo had close relationship by marriages of convenience. Because he was a very powerful man during Emperor Wuzong's era, he could become the King of Shenyang where many Korean people lived in China. However, he lost his power in the court of Yuan after the death of Emperor Wuzong. Because the Yuan Dynasty made Chungseon abdicate the crown of the Goryeo in 1313, the personal union was ended. King Chungsuk, Chungseon's eldest son, became the new King of Goryeo. In 1316, the Yuan Dynasty made Chungseon abdicate the crown of Shen in favour of Wang Go, one of his nephews, resulting in him becoming the new King of Shen.
The duchies of Saxe-Weimar and Saxe-Eisenach were in personal union from 1741, when the ruling house of Saxe-Eisenach died out, until 1809, when they were merged into the single duchy of Saxe-Weimar-Eisenach.
The duchies of Schwarzburg-Rudolstadt and Schwarzburg-Sondershausen were in personal union from 1909, when Prince Günther of Schwarzburg-Rudolstadt succeeded also to the throne of Schwarzburg-Sondershausen, until 1918, when he (and all the other German monarchs) abdicated.

Christology (from Greek Χριστός Khristós and -λογία, -logia), literally "the understanding of Christ," is the study of the nature (person) and work (role in salvation) of Jesus Christ. It studies Jesus Christ's humanity and divinity, and the relation between these two aspects; and the role he plays in salvation.
The earliest Christian writings gave several titles to Jesus, such as Son of Man, Son of God, Messiah, and Kyrios, which were all derived from the Hebrew scriptures. These terms centered around two themes, namely "Jesus as a preexistent figure who becomes human and then returns to God," and "Jesus as a creature elected and 'adopted' by God."From the second to the fifth centuries, the relation of the human and divine nature of Christ was a major focus of debates in the early church and at the first seven ecumenical councils. The Council of Chalcedon in 451 issued a formulation of the hypostatic union of the two natures of Christ, one human and one divine, "united with neither confusion nor division". Most of the major branches of Western Christianity and Eastern Orthodoxy subscribe to this formulation, while many branches of Oriental Orthodox Churches reject it, subscribing to miaphysitism.Croatia in union with Hungary
The Kingdom of Croatia (Latin: Regnum Croatiae; Croatian: Kraljevina Hrvatska or Hrvatsko kraljevstvo, Hrvatska zemlja) entered a personal union with the Kingdom of Hungary in 1102, after a period of rule of kings from the Trpimirović and Svetoslavić dynasties and a succession crisis following the death of king Demetrius Zvonimir. With the coronation of King Coloman of Hungary as "King of Croatia and Dalmatia" in 1102 in Biograd, the realm passed to the Árpád dynasty until 1301, when the (male) line of the dynasty died out. Then, kings from the Capetian House of Anjou, who were also cognatic descendants of the Árpád kings, ruled the kingdoms. Later centuries were characterized by conflicts with the Mongols, who sacked Zagreb in 1242, competition with Venice for control over Dalmatian coastal cities, and internal warfare among Croatian nobility. Various powerful nobles emerged in the time period, like Paul I Šubić of Bribir and Hrvoje Vukčić Hrvatinić, that secured de facto independence for their realms. The Ottoman incursion into Europe in the 16th century significantly reduced Croatian territories and left the country weak and divided. After the death of Louis II in 1526 during the Battle of Mohács and a brief period of dynastic dispute, both crowns passed to the Austrian House of Habsburg, and the realms became part of the Habsburg Monarchy.
Some of the terms of Coloman's coronation and the later status of the Croatian nobles are detailed in the Pacta Conventa, a document preserved only in transcript from the 14th century. The precise terms of this relationship became a matter of dispute in the 19th century; nonetheless, even in dynastic union with Hungary, institutions of separate Croatian statehood were maintained through the Sabor (an assembly of Croatian nobles) and the ban (viceroy). In addition, the Croatian nobles retained their lands and titles.Denmark–Norway
Denmark–Norway (Danish and Norwegian: Danmark–Norge), also known as the Dano–Norwegian Realm, the Oldenburg Monarchy or the Oldenburg realms, was an early modern multi-national and multi-lingual real union consisting of the Kingdom of Denmark, the Kingdom of Norway (including the Norwegian overseas possessions: the Faroe Islands, Iceland, Greenland, et cetera), the Duchy of Schleswig, and the Duchy of Holstein. The state also claimed sovereignty over two historical peoples: Wends and Goths. Denmark–Norway had several colonies, namely the Danish Gold Coast, the Nicobar Islands, Serampore, Tharangambadi, and the Danish West Indies.
The state's inhabitants were mainly Danes, Norwegians, and Germans, and also included Faroese, Icelanders and Inuit in the Norwegian overseas possessions, a Sami minority in northern Norway, as well as indigenous peoples and enslaved Africans in the colonies. The main cities of Denmark–Norway were Copenhagen, Christiania (Oslo), Altona, Bergen and Trondheim, and the primary official languages were Danish and German, but Norwegian, Icelandic, Faroese, Sami and Greenlandic were also spoken locally.In 1380, Olaf II of Denmark inherited the Kingdom of Norway, titled as Olaf IV, after the death of his father Haakon VI of Norway, who was married to Olaf's mother Margrete I. Margrete I was ruler of Norway from her son's death in 1387 until her own death in 1412. Denmark, Norway, and Sweden established and formed the Kalmar Union in 1397. Following Sweden's departure in 1523, the union was effectively dissolved. From 1536/1537, Denmark and Norway formed a personal union that would eventually develop into the 1660 integrated state called Denmark–Norway by modern historians, at the time sometimes referred to as the "Twin Kingdoms," "the Monarchy" or simply "His Majesty". Prior to 1660, Denmark–Norway was de jure a constitutional and elective monarchy in which the King's power was somewhat limited; in that year it became one of the most stringent absolute monarchies in Europe. Even after 1660, Denmark–Norway consisted of three formally separate parts, and Norway kept its separate laws and some institutions, and separate coinage and army.
The Dano-Norwegian union lasted until 1814, when the Treaty of Kiel decreed that Norway (except for the Faroe Islands, Iceland, and Greenland) be ceded to Sweden. The treaty however, was not recognised by Norway, which successfully resisted the attempt in the 1814 Swedish–Norwegian War. Norway thereafter entered into a much looser personal union with Sweden as one of two equal kingdoms until 1905, when the union was dissolved and both kingdoms became independent.Dual monarchy
Dual monarchy occurs when two separate kingdoms are ruled by the same monarch, follow the same foreign policy, exist in a customs union with each other and have a combined military but are otherwise self-governing. The term is typically used to refer to Austria-Hungary, a dual monarchy that existed from 1867 to 1918 that spanned across parts of Central and Eastern Europe.
In the 1870s, using the Dual Monarchy of Austria–Hungary as a model, the Prince of Wales (later King Edward VII) and William Ewart Gladstone proposed that Ireland and Great Britain form a dual monarchy. Their efforts were unsuccessful, but the idea was later used in 1904 by Arthur Griffith in his seminal work, The Resurrection of Hungary. Griffith noted how in 1867 Hungary went from being part of the Austrian Empire to a separate co-equal kingdom in Austria-Hungary. Though not a monarchist himself, Griffith advocated such an approach for the Anglo-Irish relationship. The idea was not embraced by other Irish political leaders, and Ireland eventually fought a war of independence (1919–1921) to leave the Union of Great Britain and Ireland.
Later historians have used the term to refer to other examples where one king ruled two states, such as Henry V and Henry VI, who were effectively kings of both England and France in the fifteenth century as a result of the formation of a puppet state in a large area of France during the Hundred Years' War, Denmark–Norway, a dual monarchy that existed from 1537 to 1814, the Iberian Union between Portugal and Spain (1580–1640), and the Polish-Lithuanian Commonwealth (1569–1795).A dual monarchy is not necessarily a personal union. In a personal union two or more kingdoms are ruled by the same person but there are no other shared government structures. States in personal union with each other have separate militaries, separate foreign policies and separate customs duties. In this sense Austria–Hungary was not a mere personal union, as both states shared a cabinet that governed foreign policy, the Army and common finances.Duchy of Warsaw
The Duchy of Warsaw (Polish: Księstwo Warszawskie, French: Duché de Varsovie, German: Herzogtum Warschau) was a Polish state established by Napoleon I in 1807 from the Polish lands ceded by the Kingdom of Prussia under the terms of the Treaties of Tilsit. The duchy was held in personal union by one of Napoleon's allies, King Frederick Augustus I of Saxony. Following Napoleon's failed invasion of Russia, the duchy was occupied by Prussian and Russian troops until 1815, when it was formally partitioned between the two countries at the Congress of Vienna. It covered the central and eastern part of present Poland and minor parts of present Lithuania and Belarus.Electorate of Brunswick-Lüneburg
The Electorate of Brunswick-Lüneburg (German: Kurfürstentum Braunschweig-Lüneburg) was an Electorate of the Holy Roman Empire, located in northwestern Germany. It was colloquially known as the Electorate of Hanover (German: Kurfürstentum Hannover or simply German: Kurhannover), after its capital city of Hanover. For most of its existence, the electorate was ruled in personal union with Great Britain.
The Duchy of Brunswick-Lüneburg had been split in 1269 between different branches of the House of Welf. The Principality of Calenberg, ruled by a cadet branch of the family, emerged as the largest and most powerful of the Brunswick-Lüneburg states. In 1695, the Holy Roman Emperor elevated the Prince of Calenberg to the College of Electors, creating the new Electorate of Brunswick-Lüneburg. The fortunes of the Electorate were tied to those of Great Britain by the Act of Settlement 1701 and Act of Union 1707, which settled the succession to the British throne on Queen Anne's nearest Protestant relative, the Electress Sophia of Hanover, and her descendants.
The Prince-Elector of Hanover became King of Great Britain in 1714. As a consequence, a reluctant Britain was forced time and again to defend the King's German possessions. However, Hanover remained a separately ruled territory with its own governmental bodies, and the country had to sign a treaty with Great Britain whenever Hanoverian troops fought on the British side of a war. Merged into the Napoleonic Kingdom of Westphalia in 1807, it was re-established as the Kingdom of Hanover in 1814, and the personal union with the British crown lasted until 1837.Frederick I of Prussia
Frederick I (German: Friedrich I.) (11 July 1657 – 25 February 1713), of the Hohenzollern dynasty, was (as Frederick III) Elector of Brandenburg (1688–1713) and Duke of Prussia in personal union (Brandenburg-Prussia). The latter function he upgraded to royalty, becoming the first King in Prussia (1701–1713). From 1707 he was in personal union the sovereign prince of the Principality of Neuchâtel (German: Fürstentum Neuenburg). He was also the paternal grandfather of Frederick the Great.House of Hanover
The House of Hanover (German: Haus Hannover), whose members are known as Hanoverians (), is a German royal house that ruled Hanover, Great Britain, and Ireland at various times during the 17th through 20th centuries. The house originated in 1635 as a cadet branch of the House of Brunswick-Lüneburg, growing in prestige until Hanover became an Electorate in 1692. George I became the first Hanoverian monarch of Great Britain and Ireland in 1714. At 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. The last reigning members of the House lost the Duchy of Brunswick in 1918 when Germany became a republic.
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.Kalmar Union
The Kalmar Union (Danish, Norwegian, and Swedish: Kalmarunionen; Latin: Unio Calmariensis) was a personal union that from 1397 to 1523 joined under a single monarch the three kingdoms of Denmark, Sweden (then including most of Finland's populated areas), and Norway, together with Norway's overseas dependencies (then including Iceland, Greenland, the Faroe Islands, and the Northern Isles). The union was not quite continuous; there were several short interruptions. Legally, the countries remained separate sovereign states, but with their domestic and foreign policies being directed by a common monarch.
One main impetus for its formation was to block German expansion northward into the Baltic region. The main reason for its failure to survive was the perpetual struggle between the monarch, who wanted a strong unified state, and the Swedish and Danish nobility, which did not. Diverging interests (especially the Swedish nobility's dissatisfaction with the dominant role played by Denmark and Holstein) gave rise to a conflict that would hamper the union in several intervals from the 1430s until its definitive breakup in 1523, when Gustav Vasa was elected as king of Sweden.Norway continued to remain a part of the realm of Denmark–Norway under the Oldenburg dynasty for nearly three centuries, until its dissolution in 1814. The ensuing loose union between Sweden and Norway lasted until 1905, when a grandson of the incumbent king of Denmark was elected as king of Norway; his direct descendants still reign in Norway.Kingdom of England
The Kingdom of England (Anglo-Norman and French: Royaume d'Angleterre) was a sovereign state on the island of Great Britain from 927, when it emerged from various Anglo-Saxon kingdoms until 1707, when it united with Scotland to form the Kingdom of Great Britain.
On 12 July 927, the various Anglo-Saxon kingdoms were united by Æthelstan (r. 927–939) to form the Kingdom of England. In 1016, the kingdom became part of the North Sea Empire of Cnut the Great, a personal union between England, Denmark and Norway. The Norman conquest of England in 1066 led to the transfer of the English capital city and chief royal residence from the Anglo-Saxon one at Winchester to Westminster, and the City of London quickly established itself as England's largest and principal commercial centre.Histories of the kingdom of England from the Norman conquest of 1066 conventionally distinguish periods named after successive ruling dynasties: Norman 1066–1154, Plantagenet 1154–1485, Tudor 1485–1603 and Stuart 1603–1714 (interrupted by the Interregnum (England) of 1649–1660).
Dynastically, all English monarchs after 1066 ultimately claim descent from the Normans; the distinction of the Plantagenets is merely conventional, beginning with Henry II (reigned 1154–1189) as from that time, the Angevin kings became "more English in nature"; the houses of Lancaster and York are both Plantagenet cadet branches, the Tudor dynasty claimed descent from Edward III via John Beaufort and James VI and I of the House of Stuart claimed descent from Henry VII via Margaret Tudor.
The completion of the conquest of Wales by Edward I in 1284 put Wales under the control of the English crown. Edward III (reigned 1327–1377) transformed the Kingdom of England into one of the most formidable military powers in Europe; his reign also saw vital developments in legislation and government—in particular the evolution of the English parliament. From the 1340s the kings of England also laid claim to the crown of France, but after the Hundred Years' War and the outbreak of the Wars of the Roses in 1455, the English were no longer in any position to pursue their French claims and lost all their land on the continent, except for Calais. After the turmoils of the Wars of the Roses, the Tudor dynasty ruled during the English Renaissance and again extended English monarchical power beyond England proper, achieving the full union of England and the Principality of Wales in 1542. Henry VIII oversaw the English Reformation, and his daughter Elizabeth I (reigned 1558–1603) the Elizabethan Religious Settlement, meanwhile establishing England as a great power and laying the foundations of the British Empire by claiming possessions in the New World.
From the accession of James VI and I in 1603, the Stuart dynasty ruled England in personal union with Scotland and Ireland. Under the Stuarts, the kingdom plunged into civil war, which culminated in the execution of Charles I in 1649. The monarchy returned in 1660, but the Civil War had established the precedent that an English monarch cannot govern without the consent of Parliament. This concept became legally established as part of the Glorious Revolution of 1688.
From this time the kingdom of England, as well as its successor state the United Kingdom, functioned in effect as a constitutional monarchy. On 1 May 1707, under the terms of the Acts of Union 1707, the kingdoms of England and Scotland united to form the Kingdom of Great Britain.Kingdom of Hanover
The Kingdom of Hanover (German: Königreich Hannover) was established in October 1814 by the Congress of Vienna, with the restoration of George III to his Hanoverian territories after the Napoleonic era. It succeeded the former Electorate of Brunswick-Lüneburg (known informally as the Electorate of Hanover), and joined 38 other sovereign states in the German Confederation in June 1815. The kingdom was ruled by the House of Hanover, a cadet branch of the House of Welf, in personal union with the United Kingdom of Great Britain and Ireland until 1837. Since its monarch resided in London, a viceroy (usually a younger member of the British Royal Family) handled the administration of the Kingdom of Hanover.
The personal union with the United Kingdom ended in 1837 upon the accession of Queen Victoria because females could not inherit the Hanoverian throne, so her uncle became the ruler of Hanover. Hanover backed the losing side in the Austro-Prussian War and was conquered by Prussia in 1866, subsequently becoming a Prussian province. Along with the rest of Prussia, Hanover became part of the German Empire upon unification in January 1871. Briefly revived as the State of Hanover in 1946, the state was subsequently merged with some smaller states to form the current state of Lower Saxony in West Germany, later Germany.Kingdom of Poland (1385–1569)
The Kingdom of Poland (Polish: Królestwo Polskie; Latin: Regnum Poloniae) and the Grand Duchy of Lithuania joined in a personal union established by the Union of Krewo (1385). The union was transformed into a closer one by the Union of Lublin in 1569, which was shortly followed by the end of the Jagiellon dynasty, which had ruled Poland for two centuries.List of British monarchs
There have been 12 monarchs of the Kingdom of Great Britain and the United Kingdom (see Monarchy of the United Kingdom) since the merger of the Kingdom of England and the Kingdom of Scotland on 1 May 1707. England and Scotland had been in personal union under the House of Stuart since 24 March 1603.
On 1 January 1801, Great Britain merged with the Kingdom of Ireland (also previously in personal union with Great Britain) to form the United Kingdom of Great Britain and Ireland. After most of Ireland left the union on 6 December 1922, its name was amended on 12 April 1927 to the United Kingdom of Great Britain and Northern Ireland.List of Danish monarchs
This is a list of Danish monarchs, that is, the Kings and Queens regnant of Denmark. This includes:
The Kingdom of Denmark (up to 1397)
Personal union of Denmark and Norway (1380–1397)
The Kalmar Union (1397–1536)
Union of Denmark, Norway and Sweden (1397–1523)
Union of Denmark and Norway (1523–1536)
The Kingdom of Denmark-Norway (1536–1814)
The Kingdom of Denmark (1814–present)
Iceland (since the union between Denmark and Norway in 1380; independent kingdom in a personal union with Denmark 1918–1944; a sovereign republic since 1944)
Greenland (since the union between Denmark and Norway in 1380; effective Danish control began in 1721; integrated into the Danish realm in 1953; internal home rule introduced 1979; self-determination assumed in 2009; Greenland has two out of 179 seats in the Danish parliament Folketinget)
Faroe Islands (since the union between Denmark and Norway in 1380; County of Denmark 1816–1948; internal home rule introduced 1948; The Faroe Islands have two out of 179 seats in the Danish parliament Folketinget)The house of Oldenburg held the Danish Crown between 1448 and 1863, when it passed to the house of Schleswig-Holstein-Sonderburg-Glücksburg, a cadet branch of the same house, patrilineally descended from King Christian III of Denmark. The kingdom had been elective (although the eldest son or brother of the previous king was usually elected) until 1660, when it became hereditary and absolutist. Until 1864 Denmark was also united in a personal union with the duchies of Holstein and Saxe-Lauenburg (1814–1864), and in a political and personal union with the Duchy of Schleswig.List of historic states of Italy
Italy, up until the Italian unification in 1861, was a conglomeration of city-states, republics, and other independent entities. The following is a list of the various Italian states during that period.Monarchy of Ireland
A monarchical system of government existed in Ireland from ancient times until—for what became the Republic of Ireland—the early twentieth century. Northern Ireland, as part of the United Kingdom, remains under a monarchical system of government. The Gaelic kingdoms of Ireland ended with the Norman invasion of Ireland, when the kingdom became a fief of the Holy See under the Lordship of the King of England. This lasted until the Parliament of Ireland conferred the crown of Ireland upon King Henry VIII of England during the English Reformation. The monarch of England held the crowns of England and Ireland in a personal union. The Union of the Crowns in 1603 expanded the personal union to include Scotland. The personal union between England and Scotland became a political union with the enactments of the Acts of Union 1707, which created the Kingdom of Great Britain. The crowns of Great Britain and Ireland remained in personal union until it was ended by the Acts of Union 1800, which united Ireland and Great Britain into the United Kingdom of Great Britain and Ireland from January 1801 until December 1922.
After that date, most of Ireland left the United Kingdom to become the largely independent Irish Free State, a dominion within the British Empire; the remaining part, Northern Ireland, elected to remain in the United Kingdom. Both the Free State and the United Kingdom, which changed its name to the United Kingdom of Great Britain and Northern Ireland in 1927, had the same person as monarch: George V. In 1937, the year after George V's death, the Free State adopted a new constitution which changed the state's name to Ireland (or Éire) and removed all mention of the monarch. In April 1949, Ireland was declared a republic, with the description of the Republic of Ireland, and it left the Commonwealth of Nations. Since April 1949, the only part of the island of Ireland that has retained a monarchical system is Northern Ireland (as part of the United Kingdom of Great Britain and Northern Ireland).Monarchy of Luxembourg
The Grand Duke of Luxembourg is the monarchical head of state of Luxembourg. Luxembourg has been a grand duchy since 15 March 1815, when it was created from territory of the former Duchy of Luxembourg. It was in personal union with the United Kingdom of the Netherlands until 1890 under the House of Orange-Nassau. Luxembourg is the world's only sovereign grand duchy and since 1815, there have been nine monarchs, including the incumbent, Henri.Polish–Lithuanian union
The term Polish–Lithuanian Union refers to a series of acts and alliances between the Kingdom of Poland and the Grand Duchy of Lithuania that lasted for prolonged periods of time and led to the creation of the Polish–Lithuanian Commonwealth—the "Republic of the Two Nations"—in 1569 and eventually to the creation of a short-lived unitary state in 1791.Important events in the process of union included:
1385 – Union of Krewo – a personal union that brought the Grand Duke of Lithuania, Jogaila, to the Polish throne
1401 – Union of Vilnius and Radom – strengthened the Polish–Lithuanian union
1413 – Union of Horodło – heraldic union which granted many szlachta rights to Lithuanian nobility
1432 (1432–34) – Union of Grodno, a declarative attempt to renew closer union
1499 – Union of Kraków and Vilnius, in which the personal union became a dynastic union, recognising the sovereignty of Lithuania and describing interaction between the two states
1501 – Union of Mielnik – a renewal of the personal union
July 1, 1569 – Union of Lublin – a real union that resulted in creation of the semi-federal, semi-confederal Republic of the Two Nations (Polish–Lithuanian Commonwealth)
May 3, 1791 – Polish Constitution of May 3, 1791: abolished the Elective monarchy and turned it into a hereditary monarchy, and established a common state, the Rzeczpospolita Polska (the Polish Commonwealth) in their place. The Reciprocal Guarantee of Two Nations modified these changes, stressing the continuity of bi-national status of the state. The changes were reversed completely in 1792 under pressure from forces of the Russian Empire.Treaty of Kiel
The Treaty of Kiel (Norwegian: Kieltraktaten) or Peace of Kiel (Swedish and Norwegian: Kielfreden or freden i Kiel) was concluded between the United Kingdom of Great Britain and Ireland and the Kingdom of Sweden on one side and the Kingdoms of Denmark and Norway on the other side on 14 January 1814 in Kiel. It ended the hostilities between the parties in the ongoing Napoleonic Wars, where the United Kingdom and Sweden were part of the anti-French camp (the Sixth Coalition) while Denmark–Norway was allied to Napoleon Bonaparte.Frederick VI of Denmark joined the anti-French alliance, ceded Heligoland to George III of the United Kingdom, and further ceded the Kingdom of Norway to Charles XIII of Sweden in return for Swedish Pomerania. Specifically excluded from the exchange were the Norwegian dependencies of Greenland, Iceland and the Faroe Islands, which remained in the union with Denmark. (Norway would unsuccessfully contest the Danish claim to all of Greenland in the Eastern Greenland Case of 1931–33.)
However, not all provisions of the treaty would come into force. Norway declared its independence, adopted a constitution and elected Crown Prince Christian Frederik as its own king. Sweden therefore refused to hand over Swedish Pomerania, which instead passed to Prussia after the Congress of Vienna in 1815. After a short war with Sweden, Norway accepted entering into a personal union with Sweden at the Convention of Moss. King Christian Frederik abdicated after convening an extraordinary Storting, which revised the Constitution to allow for the Union. It was formally established when the Storting elected Charles XIII as king of Norway on 4 November 1814.
