Condominium (international law) in the context of "Treaty of the Pyrenees"

The Albanian Declaration of Independence (Albanian: Deklarata e Pavarësisë) was the declaration of independence of Albania from the Ottoman Empire. Independent Albania was proclaimed in Vlorë on 28 November 1912. Six days later the Assembly of Vlorë formed the first Government of Albania which was led by Ismail Qemali and the Council of Elders (Pleqnia).

The success of the Albanian Revolt of 1912 sent a strong signal to the neighboring countries that the Ottoman Empire was weak. The Kingdom of Serbia opposed the plan for an Albanian Vilayet, preferring a partition of the European territory of the Ottoman Empire among the four Balkan allies. Balkan allies planned the partition of the European territory of the Ottoman Empire among them and in the meantime the territory conquered during First Balkan War was agreed to have status of the Condominium. That was the reason for Qemali to organize an All-Albanian Congress in Vlorë.

The Anglo-Egyptian Sudan (Arabic: السودان الإنجليزي المصري as-Sūdān al-Inglīzī al-Maṣrī) was a condominium of the United Kingdom and Egypt between 1899 and 1956, corresponding to the territory of what is now both Sudans and parts of southeastern Libya. Legally, sovereignty and administration were shared between both Egypt and the United Kingdom, but in practice the structure of the condominium ensured effective British control over Sudan, with Egypt having limited local power and influence. In the meantime, Egypt itself fell under increasing British influence. Following the Egyptian Revolution of 1952, Egypt pushed for an end to the condominium, and the independence of Sudan. By agreement between Egypt and the United Kingdom in 1953, Sudan was granted independence as the Republic of the Sudan on 1 January 1956. In 2011, the south of Sudan itself became independent as the Republic of South Sudan.

Muhammad Ali took control of Egypt in 1805, and while he was nominally a vassal of the Ottoman Empire, Egypt under his rule acted as a virtually independent state. Seeking to supplant and ultimately replace the Ottoman Empire as the dominant regional power, Muhammad Ali declared himself Khedive, and expanded Egypt's borders both southwards into Sudan, and eastwards into the Levant and Arabia, the latter at the expense of the Ottoman Empire. Territory in Sudan was annexed by Egypt, and governed as an integral part of the country, with Sudanese granted Egyptian citizenship. Ultimately, the intervention of the Great Powers in support of the Ottoman Empire forced Egypt to return all Levantine and Arabian territory to the Ottomans upon Muhammad Ali's death. However, there was no such impediment to Egypt's southward expansion.

An island is a landmass (smaller than a continent) that is surrounded by water. Many island countries are spread over an archipelago, as is the case with Indonesia, Japan, and the Philippines—these countries consist of thousands of islands. Others consist of a single island, such as Barbados, Dominica, and Nauru; a main island and some smaller islands, such as Cuba, Iceland, and Sri Lanka; a part of an island, such as Brunei, the Dominican Republic, East Timor, and the Republic of Ireland; or one main island but also sharing borders in other islands, such as the United Kingdom (Great Britain and a part of Ireland).

The list also includes two states in free association with New Zealand, the Cook Islands and Niue, as well as two states with limited diplomatic recognition which have de facto control over territories entirely on the islands, Northern Cyprus and Taiwan. In total, 50 island countries have been included in the lists.

A client state, in the context of international relations, is an umbrella term that broadly refers to any state economically, politically, and militarily subordinated to a more powerful controlling state. It typically describes a bilateral relationship that is mutually beneficial, characterized by different but shared obligations.

Variants of a client state are associated state, dominion, condominium, self-governing colony, neo-colony, protectorate, puppet state, satellite state, vassal state and tributary state.

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.

The first Paréage of Andorra (Catalan: Tractat de pareatge) was a feudal charter signed in Lleida on 8 September 1278. It codified a lay and ecclesiastical agreement between the Count of Foix, Roger-Bernard III, and the Bishop of Urgell, Pere d'Urtx, establishing their joint sovereignty over the territory of Andorra. The paréage established the system of condominium in Andorra, placing it under suzerainty of both lords. This system was later ratified in 1993 by the signing of the Constitution of Andorra. The charter underpins the modern legal status of Andorra.

A second paréage was signed on 6 November 1288, which supplemented and addressed a number of clauses in the first paréage. Together, these two paréages comprised the first basic law of Andorra, and were the nation's most important constitutional documents until the ratification of the Constitution in 1993.

The co-princes of Andorra are jointly the heads of state (Catalan: cap d'estat) of the Principality of Andorra, a landlocked microstate lying in the Pyrenees between France and Spain.

Founded in 1278 by a treaty between the bishop of Urgell and the count of Foix, this unique diarchical arrangement has persisted through the Middle Ages to the present. Following the transfer of the count of Foix's claims to the Crown of France and, subsequently, to the head of state of the French Republic, the current arrangement has the bishop of Urgell (Josep-Lluís Serrano Pentinat) serving as the episcopal co-prince and the president of France (Emmanuel Macron) as the lay co-prince. Each co-prince appoints a personal representative. The episcopal co-prince is currently represented by Eduard Ibáñez and the lay co-prince by Patrice Faure.
