Real union in the context of "Denmark"

A political union is a type of political entity which is composed of, or created from, smaller polities or the process which achieves this. These smaller polities are usually called federated states and federal territories in a federal government; they are called prefectures, regions, or provinces in the case of a centralised government. This form of government may be created through voluntary and mutual cession and is described as unionism by its constituent members and proponents. In other cases, it may arise from political unification, characterised by coercion and conquest. The unification of separate states which, in the past, had together constituted a single entity is known as reunification. Unlike a personal union or real union, the individual constituent entities may have devolution of powers but are subordinate to a central government or coordinated in some sort of organization. In a federalised system, the constituent entities usually have internal autonomy, for example in the setup of police departments, and share power with the federal government, for whom external sovereignty, military forces, and foreign affairs are usually reserved. The union is recognised internationally as a single political entity. A political union may also be called a legislative union or state union.A union may be effected in many forms, broadly categorized as:

• Incorporating union
• Incorporating annexation
• Federal union
• Federative annexation
• Mixed unions

The Polish–Lithuanian Commonwealth, also referred to as Poland–Lithuania or the First Polish Republic (Polish: I Rzeczpospolita), was a federative real union between the Kingdom of Poland and the Grand Duchy of Lithuania, existing from 1569 to 1795. This state was among the largest, most populated countries of 16th- to 18th-century Europe. At its peak in the early 17th century, the Commonwealth spanned approximately 1,000,000 km (390,000 sq mi) and supported a multi-ethnic population of around 12 million as of 1618. The official languages of the Commonwealth were Polish and Latin, with Catholicism as the state religion.

The Union of Lublin established the Commonwealth as a single entity on 1 July 1569. The two nations had previously been in a personal union since the Krewo Agreement of 1385 (Polish–Lithuanian union) and the subsequent marriage of Queen Jadwiga of Poland to Grand Duke Jogaila of Lithuania, who was crowned as Władysław II Jagiełło, jure uxoris King of Poland. Their descendant, Sigismund II Augustus, enforced the merger to strengthen frontiers of his dominion and maintain unity. As he remained childless, his death in 1572 marked the end of the Jagiellonian dynasty. It introduced an elective monarchy, whereupon members of domestic noble families or external dynasties were elected to the throne for life.

A personal union is a combination of two or more monarchical states that have the same monarch while their boundaries, laws, and interests remain distinct. A real union, by contrast, involves the constituent states being to some extent interlinked, such as by sharing some limited governmental institutions. It differs from a federation in that each constituent state has an independent government, whereas a federal state is united by a central government. The ruler in a personal union does not need to be a hereditary monarch.

The term was coined by German jurist Johann Stephan Pütter, introducing it into Elementa iuris publici germanici (Elements of German Public Law) of 1760.

The Union of Lublin (Polish: Unia lubelska; Lithuanian: Liublino unija) was signed on 1 July 1569 in Lublin, Poland, and created a single state, the Polish–Lithuanian Commonwealth, one of the largest countries in Europe at the time. It replaced the personal union of the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania with a real union and an elective monarchy, as Sigismund II Augustus, the last of the Jagiellons, remained childless after three marriages. In addition, the autonomy of Royal Prussia was largely abandoned. The Duchy of Livonia, tied to Lithuania in real union since the Union of Grodno (1566), became a Polish–Lithuanian condominium.

The Commonwealth was ruled by a single elected monarch who carried out the duties of King of Poland and Grand Duke of Lithuania, and governed with a common Senate and parliament (the Sejm). The Union is seen by some as an evolutionary stage in the Polish–Lithuanian alliance and personal union, necessitated also by Lithuania's dangerous position in wars with Russia.

Denmark–Norway was a 16th-to-19th-century multi-national and multi-lingual real union consisting of the Kingdom of Denmark, the Kingdom of Norway (including the then Norwegian overseas possessions: the Faroe Islands, Iceland, Greenland, and other possessions), the Duchy of Schleswig, and the Duchy of Holstein. The state also claimed sovereignty over three historical peoples: Frisians, Gutes and Wends. Denmark–Norway had several colonies, namely the Danish Gold Coast, Danish India (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 other indigenous peoples. 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.

Anglo-Irish people (Irish: Angla-Éireannach) denotes an ethnic, social and religious grouping consisting mostly of the descendants and successors of the English Protestant Ascendancy in Ireland. Predominantly, the Anglo-Irish belong to the Anglican Church of Ireland, which was the established Church of Ireland until 1871 or, to a lesser extent, to one of the English Dissenting Churches, such as Baptists, Presbyterians, the Methodist Church. However, some were Roman Catholics. They often defined themselves simply as "British", or less frequently as "Anglo-Irish", "Irish" or "English". Many became notable as administrators in the British Empire or as senior army and naval officers. The Kingdom of England and Great Britain were in a real union with the Kingdom of Ireland for over a century, before politically uniting into the United Kingdom of Great Britain and Ireland in 1801.

The term is not usually applied to Presbyterians in the province of Ulster, whose ancestry is mostly Lowland Scottish, rather than English or Irish, and who are sometimes identified as Ulster Scots. The Anglo-Irish hold a wide range of political views, with some being outspoken Irish nationalists, but most overall being Unionists. And while most of the Anglo-Irish originated in the English diaspora in Ireland, others were descended from families of the old Gaelic nobility of Ireland.

A dynastic union is a type of union in which different states are governed beneath the same dynasty, with their boundaries, their laws, and their interests remaining distinct from each other.

It is a form of association looser than a personal union, when several states share the same monarch, and a real union, when they have common institutions in addition to the same monarch.
