De jure

A national language is a language (or language variant, e.g. dialect) that has some connection—de facto or de jure—with a nation. The term is applied quite differently in various contexts. One or more languages spoken as first languages in the territory of a country may be referred to informally or designated in legislation as national languages of the country. National languages are mentioned in over 150 world constitutions.

C.M.B. Brann, with particular reference to India, suggests that there are "four quite distinctive meanings" for national language in a polity:

Constantine VIII (Greek: Κωνσταντῖνος, romanized: Kōnstantīnos; 960 – 11/12 November 1028) was de jure Byzantine emperor from 962 until his death. He was the younger son of Emperor Romanos II and Empress Theophano. He was nominal co-emperor from 962, successively with his father; stepfather, Nikephoros II Phokas; uncle, John I Tzimiskes; and brother, Basil II. Basil's death in 1025 left Constantine as the sole emperor. He occupied the throne for 66 years in total, making him de jure the longest-reigning amongst all Roman emperors since Augustus.

Constantine displayed a lifelong lack of interest in politics, statecraft and the military, and during his brief sole reign the government of the Byzantine Empire suffered from mismanagement and neglect. He had no sons and was instead succeeded by Romanos Argyros, husband of his daughter Zoe.

The Morocco–Western Sahara border is 444 kilometres (276 mi) in length and runs from Atlantic Ocean in the west, to the tripoint with Algeria in the east. The border has existed purely in a de jure sense since Morocco's annexation of Western Sahara in 1976–1979.

Lausanne (/loʊˈzæn/ loh-ZAN, US also /loʊˈzɑːn/ loh-ZAHN; French: [lozan] ; Arpitan: Losena [lɔˈzəna] ) is the capital and largest city of the Swiss French-speaking canton of Vaud, in Switzerland. The Olympic capital, it is a hilly city situated on the shores of Lake Geneva, about halfway between the Jura Mountains and the Alps, and facing the French town of Évian-les-Bains across the lake. Lausanne is located (as the crow flies) 51.7 kilometres (32 miles) northeast of Geneva, the nearest major city. The Federal Supreme Court of Switzerland convenes in Lausanne, although it is not the de jure capital of the nation.

The municipality of Lausanne has a population of about 150,000, making it the fourth largest city in Switzerland after Basel, Geneva, and Zurich, with the entire agglomeration area having about 420,000 inhabitants (as of January 2019). The metropolitan area of Lausanne-Geneva (including Vevey-Montreux, Yverdon-les-Bains, Valais and foreign parts), commonly designated as Arc lémanique was over 1.3 million inhabitants in 2017 and is the fastest growing in Switzerland.

Estonia, officially the Republic of Estonia, is a country in Northern Europe. It is bordered to the north by the Gulf of Finland across from Finland, to the west by the Baltic Sea across from Sweden, to the south by Latvia, and to the east by Russia. The territory of Estonia consists of the mainland, the larger islands of Saaremaa and Hiiumaa, and over 2,300 other islands and islets on the east coast of the Baltic Sea. Its capital Tallinn and Tartu are the two largest urban areas. The Estonian language, of the Finnic family, is the official language and the first language of the majority of its population of nearly 1.4 million. Estonia is one of the least populous members of the European Union and NATO.

Present-day Estonia has been inhabited since at least 9,000 BC. The medieval indigenous population of Estonia was one of the last pagan civilisations in Europe to adopt Christianity following the Northern Crusades in the 13th century. After centuries of successive rule by the Teutonic Order, Denmark, Sweden, and the Russian Empire, a distinct Estonian national identity began to emerge in the mid-19th century. This culminated in the 1918 Estonian Declaration of Independence from the then-warring Russian and German empires. Democratic throughout most of the interwar period, Estonia declared neutrality at the outbreak of World War II, but the country was repeatedly invaded and occupied, and ultimately annexed into the USSR. Throughout the de facto Soviet occupation, from World War II until 1991, Estonia's de jure state continuity was preserved by diplomatic representatives and the government-in-exile. Following the 1988–90 "Singing Revolution" against Soviet rule, full independence was restored on 20 August 1991.

The Autonomous Republic of Crimea is a de jure administrative division of Ukraine encompassing most of Crimea that was unilaterally annexed by Russia in 2014. The Autonomous Republic of Crimea occupies most of the peninsula, while the City of Sevastopol (a city with special status within Ukraine) occupies the rest.

The Cimmerians, Scythians, Greeks, Goths, Huns, Bulgars, Khazars, Byzantine Greeks, the state of Kievan Rus', Kipchaks, Italians, and Golden Horde Mongols and Tatars each controlled Crimea in its earlier history. In the 13th century, it was partly controlled by the Venetians and by the Genoese, and in the late 15th century, it was partly under Polish suzerainty. They were followed by the Crimean Khanate and the Ottoman Empire in the 15th to 18th centuries, the Russian Empire in the 18th to 20th centuries, Germany during World War II, and the Russian Soviet Federative Socialist Republic, and later the Ukrainian Soviet Socialist Republic, within the Soviet Union during the rest of the 20th century until Crimea became part of independent Ukraine with the breakup of the Soviet Union in 1991.

The Republic of Crimea is a republic of Russia, comprising most of the Crimean Peninsula, but excluding Sevastopol. Its territory corresponds to the pre-2023 territory of the Autonomous Republic of Crimea, a de jure subdivision of Ukraine. Russia occupied and annexed the peninsula in 2014, although the annexation remains internationally unrecognized.

The capital and largest city located within its borders is Simferopol, which is the second-largest city on the Crimean Peninsula. As of the 2021 Russian census, the Republic of Crimea had a population of 1,934,630.

A queen regnant (pl.: queens regnant) is a female monarch, equivalent in rank, title and position to a king. She reigns suo jure (in her own right) over a realm known as a kingdom; as opposed to a queen consort, who is married to a reigning king; or a queen regent, who is the guardian of a child monarch and rules pro tempore in the child's stead or instead of her husband who is absent from the realm, be it de jure in sharing power or de facto in ruling alone. A queen regnant is sometimes called a woman king. A princess, duchess, or grand duchess regnant is a female monarch who reigns suo jure over a principality or (grand) duchy; an empress regnant is a female monarch who reigns suo jure over an empire.

A queen regnant possesses all the powers, such as they may be, of the monarchy, whereas a queen consort or queen regent shares her spouse's or child's rank and titles but does not share the sovereignty of her spouse or child. The husband of a queen regnant traditionally does not share the queen regnant’s rank, title, or sovereignty and usually holds a lower princely title. However, the concept of a king consort is not unheard of in both contemporary and historical periods.

Nicosia, also known as Lefkosia or Lefkoşa, is the capital of Cyprus and the de jure capital of Northern Cyprus, which is geographically located in Asia. It is the southeasternmost capital city among European Union member states.

Nicosia has been continuously inhabited for over 5,500 years and has been the capital of Cyprus since the 10th century. It is the last divided capital in Europe; three years after Cyprus gained independence from British rule in 1960, the Bloody Christmas conflict between Greek Cypriots and Turkish Cypriots triggered island-wide intercommunal violence, and Nicosia's Greek Cypriot and Turkish Cypriot communities segregated into its south and north respectively in 1964. A decade later, Turkey invaded Cyprus following Greece's successful attempt to take over the island. The leaders of the takeover would later step down, but the dividing line running through Nicosia (and the rest of the island, interrupted only briefly by British military bases) became a demilitarised zone that remains under the control of Cyprus while heavily policed by the United Nations; it is now known as the United Nations Buffer Zone in Cyprus between the Republic of Cyprus, which is internationally recognised, and Northern Cyprus, which is recognised only by Turkey. The ongoing dispute between the two communities is known as the Cyprus problem.

The Emirate of Afghanistan, known internationally as the Emirate of Kabul until 1855, was an emirate in Central Asia that encompassed present-day Afghanistan, parts of present-day Iran, Pakistan, Turkmenistan and Tajikistan. The emirate emerged from its predecessor Durrani Empire, when the Barakzai dynasty prevailed in Kabul.

The history of the Emirate was dominated by the 'Great Game' between the Russian Empire and the British Empire for supremacy in Central Asia. This period was characterized by European influence in Afghanistan. The Emirate of Afghanistan continued the Durrani Empire's war with the Sikh Empire, losing control of the former Afghan stronghold of the Valley of Peshawar at the Battle of Nowshera on 14 March 1823. This was followed in 1838 by the First Anglo-Afghan War with British forces. The war eventually resulted in victory for Afghans, with the British withdrawal in 1842, and Dost Mohammad being reinstalled to the throne. However, during the Second Anglo-Afghan War (1878–1880), the British and Afghans signed the Treaty of Gandamak, which allowed the British to assume control of the Afghan territories within modern-day Pakistan as well as of Afghanistan's foreign affairs, on the condition that a subsidy be paid to the Afghans and the British military fully withdraw. Emir Amanullah Khan signed the Anglo-Afghan Treaty of 1919 following the Third Anglo-Afghan War, gaining full Afghan autonomy, and the removal of Afghanistan's status of being a de-jure British protectorate. In 1926, Amanullah Khan reformed the country as the Kingdom of Afghanistan, becoming its first King.
