Principality in the context of Feudalism

The Ottoman Empire, also known as the Turkish Empire, controlled much of Southeast Europe, West Asia, and North Africa from the 14th century to the early 20th century. It also controlled parts of southeastern Central Europe between the early 16th and early 18th centuries.

The empire emerged from a beylik, or principality, founded in northwestern Anatolia in c. 1299 by the Turkoman tribal leader Osman I. His successors conquered much of Anatolia and expanded into the Balkans by the mid-14th century, transforming their petty kingdom into a transcontinental empire. The Ottomans ended the Byzantine Empire with the conquest of Constantinople in 1453 by Mehmed II. With its capital at Constantinople and control over a significant portion of the Mediterranean Basin, the Ottoman Empire was at the centre of interactions between the Middle East and Europe for six centuries. Ruling over so many peoples, the empire granted varying levels of autonomy to its many confessional communities, or millets, to manage their own affairs per Islamic law. During the reigns of Selim I and Suleiman the Magnificent in the 16th century, the Ottoman Empire became a global power.

The term Albanian Principalities refers to a number of principalities (although they functioned more like a series of kingdoms) created in the Middle Ages in Albania and the surrounding regions in the western Balkans that were ruled by Albanian nobility. The 12th century marked the first Albanian principality, the Principality of Arbanon. It was later, however, in the 2nd half of the 14th century that these principalities became stronger, especially with the fall of the Serbian Empire after 1355. Some of these principalities were notably united in 1444 under the military alliance called League of Lezhë up to 1480 which defeated the Ottoman Empire in more than 28 battles. They covered modern day Albania, western and central Kosovo, Epirus, areas up to Corinth, western North Macedonia, southern Montenegro. The leaders of these principalities were some of the most noted Balkan figures in the 14th and 15th centuries such as Gjin Bua Shpata, Andrea II Muzaka, Gjon Zenebishi, Karl Topia, Andrea Gropa, Balsha family, Gjergj Arianiti, Gjon Kastrioti, Skanderbeg, Dukagjini family and Lek Dukagjini.

In European history, monarchy was the prevalent form of government throughout the Middle Ages, only occasionally competing with communalism, notably in the case of the maritime republics and the Swiss Confederacy.

In the early modern period (1500 - 1800 CE), Republicanism became more prevalent, but monarchy still remained predominant in Europe until the end of the 19th century. After World War I, however, most European monarchies were abolished. There remain, as of 2025, twelve sovereign monarchies in Europe. Seven are kingdoms: Denmark, Norway, Sweden, the United Kingdom, Spain, the Netherlands, and Belgium. Three are principalities: Andorra, Liechtenstein, and Monaco. Finally, Luxembourg is a grand duchy and Vatican City is a theocratic, elective monarchy ruled by the pope.

An emirate is a territory ruled by an emir, a title used by monarchs or high officeholders in the Muslim world. From a historical point of view, an emirate is a political-religious unit smaller than a caliphate. It can be considered equivalent to a principality in non-Muslim contexts.

Currently in the world, there are three emirates that are independent states (Afghanistan, Kuwait, and Qatar) and a state that consists of a federation of seven emirates (the United Arab Emirates). A great number of previously independent emirates around the world are now part of larger states.

The Principality of Montenegro (Serbian: Књажевина Црна Горa, romanized: Knjaževina Crna Gora) was a principality in Southeastern Europe that existed from 13 March 1852 to 28 August 1910. It was then proclaimed a kingdom by Nikola I, who then became King of Montenegro.

The capital was Cetinje and the Montenegrin perper was used as the state currency from 1906. The territory corresponded to the central area of modern-day Montenegro. It officially was a constitutional monarchy.

The Normans (Norman: Normaunds; French: Normands; Latin: Nortmanni/Normanni) were a population arising in the medieval Duchy of Normandy from the intermingling between Norse Viking settlers and locals of West Francia. The Norse settlements in West Francia followed a series of raids on the French northern coast mainly from what is now Denmark, although some also sailed from Norway and Sweden. These settlements were finally legitimized when Rollo, a Scandinavian Viking leader, agreed to swear fealty to King Charles III of West Francia following the siege of Chartres in 911, leading to the formation of the County of Rouen. This new fief, through kinship in the decades to come, would expand into what came to be known as the Duchy of Normandy. The Norse settlers, whom the region as well as its inhabitants were named after, adopted the language, religion, social customs and martial doctrine of the West Franks but their offspring nonetheless retained many of their traits, notably their mercenary tendencies and their fervour for adventures. The intermixing between Norse folk and native West Franks in Normandy produced an ethnic and cultural "Norman" identity in the first half of the 10th century, an identity which continued to evolve over the centuries.

The Norman dynasty had a major political, cultural and military impact on medieval Europe and the Near East. The Normans were historically famed for their martial spirit, and eventually for their Catholic piety as adherents of the Catholic orthodoxy of the Romance community. The original Norse settlers adopted the Gallo-Romance language of the Frankish land they settled, with their Old Norman dialect becoming known as Norman, Normaund or Norman French, an important literary language which is still spoken today in parts of mainland Normandy (Cotentinais and Cauchois dialects) and the nearby Channel Islands (Jèrriais and Guernésiais). The Duchy of Normandy, which arose from the Treaty of Saint-Clair-sur-Epte, was a great fief of medieval France. The Norman dukes exercised independent control of their holdings in Normandy, while at the same time being vassals owing fealty to the King of France, and under Richard I of Normandy (byname Richard sans Peur, meaning "Richard the Fearless"), the duchy was forged into a cohesive and formidable principality in feudal tenure.

The Kingdom of Romania (Romanian: Regatul României) was a constitutional monarchy that existed from 25 March [O.S. 13 March] 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I (thus beginning the Romanian royal family), until 1947 with the abdication of King Michael I and the Romanian parliament's proclamation of the Romanian People's Republic.

From 1859 to 1877, Romania evolved from a personal union of two principalities: (Moldavia and Wallachia) called the Unification of Moldavia and Wallachia also known as "The Little Union" under a single prince to an autonomous principality with a Hohenzollern monarchy. The country gained its independence from the Ottoman Empire during the 1877–1878 Russo-Turkish War (known locally as the Romanian War of Independence), after which it was forced to cede the southern part of Bessarabia in exchange for Northern Dobruja. The kingdom's territory during the reign of King Carol I, between 13 (O.S.) / 25 March 1881 and 27 September (O.S.) / 10 October 1914 is sometimes referred to as the Romanian Old Kingdom, to distinguish it from "Greater Romania", which included the provinces that became part of the state after World War I (Bessarabia, Banat, Bukovina, and Transylvania).

Moldavia (Romanian: Moldova, pronounced [molˈdova] or Țara Moldovei lit. 'The country of Moldova'; in Romanian Cyrillic: Молдова or Цара Мѡлдовєй) is a historical region and former principality in Eastern Europe, corresponding to the territory between the Eastern Carpathians and the Dniester River. An initially independent and later autonomous state, it existed from the 14th century to 1859, when it united with Wallachia (Țara Românească) as the basis of the modern Romanian state; at various times, Moldavia included the regions of Bessarabia (with the Budjak), all of Bukovina and Hertsa. It also included the region of Pokuttya for a period of time.

The western half of Moldavia is now part of Romania, the eastern side belongs to the Republic of Moldova, and the northern and southeastern parts are territories of Ukraine.

Wallachia is a geographical region of modern-day Romania, as well as one of the two historical Romanian principalities that laid the foundation for the establishment of the modern Romanian state. It is situated north of the Lower Danube and south of the Southern Carpathians. Wallachia was traditionally divided into two sections, Muntenia (Greater Wallachia) and Oltenia (Lesser Wallachia). Dobruja could sometimes be considered a third section due to its proximity and brief rule over it. Wallachia as a whole is sometimes referred to as Muntenia through identification with the larger of the two traditional sections.

Wallachia began to form as a principality around the 13th century, following the gradual unification of several smaller Romanian political entities. By 1330, the state had consolidated following Basarab I's victory in the Battle of Posada against the Kingdom of Hungary, ushering in a period of relative independence. In 1417, Wallachia was forced to accept the suzerainty of the Ottoman Empire for the first time; this suzerainty lasted until the mid-19th century. However in general Wallachia was able to preserve autonomy within the Empire as well as experience interruptions to Ottoman rule brought about by local rulers such as Vlad the Impaler and Michael the Brave and later external powers such as the Polish-Lithuanian Commonwealth and the Russian Empire.

The Principality of Bulgaria (Bulgarian: Княжество България, romanized: Knyazhestvo Balgariya) was a vassal state under the suzerainty of the Ottoman Empire. It was established by the Treaty of Berlin in 1878.

After the Russo-Turkish War ended with a Russian victory, the Treaty of San Stefano was signed by Russia and the Ottoman Empire on 3 March 1878. Under this, a large Bulgarian vassal state was agreed to, which was significantly larger: its lands encompassed nearly all ethnic Bulgarians in the Balkans, and included most of Moesia, Thrace and Macedonia, stretching from the Black Sea to the Aegean. However, the United Kingdom and Austria-Hungary were against the establishment of such a large Russian client state in the Balkans, fearing it would shift the balance of power in the Mediterranean. Due to this, the great powers convened and signed the Treaty of Berlin, superseding the Treaty of San Stefano, which never went into effect. This created a much smaller principality, alongside an autonomous Eastern Rumelia within the Ottoman Empire.

Bagratid Armenia was an independent Armenian state established by Ashot I of the Bagratuni dynasty in the early 880s following nearly two centuries of foreign domination of Greater Armenia under Arab Umayyad and Abbasid rule. With each of the two contemporary powers in the region—the Abbasids and Byzantines—too preoccupied to concentrate their forces on subjugating the region, and with the dissipation of several of the Armenian nakharar noble families, Ashot succeeded in asserting himself as the leading figure of a movement to dislodge the Arabs from Armenia.

Ashot's prestige rose as both Byzantine and Arab leaders—eager to maintain a buffer state near their frontiers—courted him. The Abbasid Caliphate recognized Ashot as "prince of princes" in 862 and, later on, as king (in 884 or 885). The establishment of the Bagratuni kingdom later led to the founding of several other Armenian principalities and kingdoms: Taron, Vaspurakan, Kars, Khachen and Syunik. During the reign of Ashot III (952/53–77), Ani became the kingdom's capital and grew into a thriving economic and cultural center.

Bey, also spelled as Baig, Bayg, Beigh, Beig, Bek, Baeg, Begh, or Beg, is a Turkic title for a chieftain, and a royal, aristocratic title traditionally applied to people with special lineages to the leaders or rulers of variously sized areas in the numerous Turkic kingdoms, emirates, sultanates and empires in Central Asia, South Asia, Southeast Europe, and the Middle East, such as the Ottomans, Timurids or the various khanates and emirates in Central Asia and the Eurasian Steppe. The feminine equivalent title was begum. The regions or provinces where "beys" ruled or which they administered were called beylik, roughly meaning "governorate" or "region" (the equivalent of a county, duchy, grand duchy or principality in Europe, depending on the size and importance of the beylik). However the exact scope of power handed to the beys varied with each country, thus there was no clear-cut system, rigidly applied to all countries defining all the possible power and prestige that came along with the title.

Today, the word is still used formally as a social title for men, similar to the way the titles "sir" and "mister" are used in the English language. Additionally, it is widely used in the naming customs of Central Asia, namely in countries such as Uzbekistan, Kazakhstan and Kyrgyzstan. Notably, the ethnic designation of Uzbeks comes from the name of Öz Beg Khan of the Golden Horde, being an example of the usage of this word in personal names and even names of whole ethnic groups. The general rule is that the honorific is used with first names and not with surnames or last names.

The German Empire (German: Deutsches Reich), also referred to as Imperial Germany, the Second Reich, or simply Germany, was the period of the German Reich from the unification of Germany in 1871 until the November Revolution in 1918, when Germany changed its form of government to a republic. The German Empire consisted of 25 states, each with its own nobility: four constituent kingdoms, six grand duchies, five duchies (six before 1876), seven principalities, three free Hanseatic cities, and one imperial territory. While Prussia was only one of the four kingdoms in the realm, it contained about two-thirds of the Empire's population and territory, and Prussian dominance was also constitutionally established, since the King of Prussia was also the German Emperor (Deutscher Kaiser).

The empire was founded on 18 January 1871, when the south German states, except for Austria, Switzerland and Liechtenstein, joined the North German Confederation. The new constitution came into force on 16 April, changing the name of the federal state to the German Empire and introducing the title of German Emperor for Wilhelm I, King of Prussia from the House of Hohenzollern. Berlin remained its capital, and Otto von Bismarck, Minister President of Prussia, became chancellor, the head of government. After 1850, the states of Germany had rapidly become industrialized. In 1871, Germany had a population of 41 million people; by 1913, this had increased to 68 million. A heavily rural collection of states in 1815, the now united Germany became predominantly urban. German factories were often larger and more modern than many of their British and French counterparts, but the preindustrial sector was more backward. The success of the German Empire in the natural sciences was such that one-third of all Nobel Prizes went to German inventors and researchers. During its 47 years of existence, the German Empire became an industrial, technological, and scientific power in Europe, and by 1913, Germany was the largest economy in continental Europe and the third largest in the world. Germany also became a great power, building the longest railway network of Europe, the world's strongest army, and a fast-growing industrial base. Starting very small in 1871, in a decade, the navy became second only to Britain's Royal Navy.

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.
