In international law, a condominium (plural either condominia, as in Latin, or condominiums) is a political territory (state or border area) in or over which multiple sovereign powers formally agree to share equal dominium (in the sense of sovereignty) and exercise their rights jointly, without dividing it into "national" zones.
Although a condominium has always been recognized as a theoretical possibility, condominia have been rare in practice. A major problem, and the reason so few have existed, is the difficulty of ensuring co-operation between the sovereign powers; once the understanding fails, the status is likely to become untenable.
The word is recorded in English since c. 1714, from Modern Latin, apparently coined in Germany c. 1700 from Latin com- "together" + dominium "right of ownership" (compare domain). A condominium of three sovereign powers is sometimes called a tripartite condominium or tridominium.

Under French law, Andorra was once considered to be a French–Spanish condominium, although it is more commonly classed as a co-principality, since it is itself a sovereign state, not a possession of one or more foreign powers. However, the position of head of state is shared ex officio by two foreigners, one of whom is the President of France, currently Emmanuel Macron, and the other the Bishop of Urgell in Spain, Joan Enric Vives Sicília.
The Potsdam Agreement was the August 1945 agreement between three of the Allies of World War II, the United Kingdom, the United States, and the Soviet Union. It concerned the military occupation and reconstruction of Germany, its borders, and the entire European Theatre of War territory. It also addressed Germany's demilitarisation, reparations and the prosecution of war criminals.
A demilitarized zone, DMZ or DZ is an area in which treaties or agreements between nations, military powers or contending groups forbid military installations, activities or personnel. A DMZ often lies along an established frontier or boundary between two or more military powers or alliances. A DMZ may sometimes form a de facto international border, such as the 38th parallel between North and South Korea. Other examples of demilitarized zones are a 120-mile (190 km) wide area between Iraq and Kuwait, Antarctica and outer space.
The Treaty of London or London Convention or similar may refer to:
The Treaty of Paris, signed on 30 May 1814, ended the war between France and the Sixth Coalition, part of the Napoleonic Wars, following an armistice signed on 23 April between Charles, Count of Artois, and the allies. The treaty set the borders for France under the House of Bourbon and restored territories to other nations. It is sometimes called the First Peace of Paris, as another one followed in 1815.
A protectorate, in its inception adopted by modern international law, is a dependent territory that has been granted local autonomy and some independence while still retaining the suzerainty of a greater sovereign state. In exchange for this, the protectorate usually accepts specified obligations, which may vary greatly, depending on the real nature of their relationship. Therefore, a protectorate remains an autonomous part of a sovereign state. They are different from colonies as they have local rulers and people ruling over the territory and experience rare cases of immigration of settlers from the country it has suzerainty of. However, a state which remains under the protection of another state but still retains independence is known as a protected state and is different from protectorates.
New Hebrides, officially the New Hebrides Condominium and named for the Hebrides Scottish archipelago, was the colonial name for the island group in the South Pacific Ocean that is now Vanuatu. Native people had inhabited the islands for three thousand years before the first Europeans arrived in 1606 from a Spanish expedition led by Portuguese navigator Pedro Fernandes de Queirós. The islands were colonised by both the British and French in the 18th century, shortly after Captain James Cook visited.
The Treaty of Sèvres was one of a series of treaties that the Central Powers signed with the Allied Powers after their defeat in World War I. Hostilities had already ended with the Armistice of Mudros. The treaty was signed on 10 August 1920, in an exhibition room at the Manufacture nationale de Sèvres porcelain factory in Sèvres, France.
The Anglo-Egyptian Sudan was a condominium of the United Kingdom and Egypt in the eastern Sudan region of northern Africa between 1899 and 1956, but in practice the structure of the condominium ensured full British control over the Sudan with Egypt having local influence instead. It attained independence as the Republic of the Sudan, which since 2011 has been split into Sudan and South Sudan.
The Tripartite Convention of 1899 concluded the Second Samoan Civil War, resulting in the formal partition of the Samoan archipelago into a German colony and a United States territory.
The Gastein Convention, also called the Convention of Badgastein, was a treaty signed at Bad Gastein in Austria on 14 August 1865. It embodied agreements between the two principal powers of the German Confederation, Prussia and Austria, over the governing of the 'Elbe Duchies' of Schleswig, Holstein and Saxe-Lauenburg.
Upon defeat of Nazi Germany in World War II, the victorious Allies asserted joint authority and sovereignty over 'Germany as a whole', defined as all territories of the former German Reich west of the Oder–Neisse line, having declared the destruction of Nazi Germany at the death of Adolf Hitler. The four powers divided 'Germany as a whole' into four occupation zones for administrative purposes, under the United States, United Kingdom, France and the Soviet Union respectively; creating what became collectively known as Allied-occupied Germany. This division was ratified at the Potsdam Conference. The four zones were as agreed in February 1945 by the United States, United Kingdom and Soviet Union meeting at the Yalta Conference; setting aside an earlier division into three zones proposed by the London Protocol.
The territorial changes of Germany include all changes in the borders and territory of Germany from its formation in 1871 to the present. Modern Germany was formed in 1871 when Otto von Bismarck unified most of the German states, with the notable exception of Austria, into the German Empire. After the First World War, Germany lost about 10% of its territory to its neighbours and the Weimar Republic was formed. This republic included territories to the east of today's German borders.
Relations between Austria and Germany are close, due to their shared history and language, with German being the official language and Germans being the largest ethnic group of both countries.
Portugal–Spain relations describes relations between the governments of the Portuguese Republic and the Kingdom of Spain. The two states make up the vast majority of the Iberian Peninsula and as such, the relationship between the two is sometimes known as Iberian relations.
The German colonization of Africa took place during two distinct periods. In the 1680s, the Margraviate of Brandenburg, then leading the broader realm of Brandenburg-Prussia, pursued limited imperial efforts in West Africa. The Brandenburg African Company was chartered in 1682 and established two small settlements on the Gold Coast of what is today Ghana. Five years later, a treaty with the king of Arguin in Mauritania established a protectorate over that island, and Brandenburg occupied an abandoned fort originally constructed there by Portugal. Brandenburg — after 1701, the Kingdom of Prussia — pursued these colonial efforts until 1721, when Arguin was captured by the French and the Gold Coast settlements were sold to the Dutch Republic.
Prussia and its predecessor, Brandenburg-Prussia, were involved in numerous conflicts during their existence as nation-states. During their military engagements they often fulfilled the role of a supporting power, especially in the 17th century. In the 18th century Prussia began to adopt an independent role in the conflicts of that time; at the latest by the time of the Silesian Wars.
