Prince in the context of "Principality"

The Kamakura shogunate (Japanese: 鎌倉幕府, Hepburn: Kamakura bakufu) was the feudal military government of Japan during the Kamakura period from 1185 to 1333.

The Kamakura shogunate was established by Minamoto no Yoritomo after victory in the Genpei War and appointing himself as shōgun. Yoritomo governed Japan as military dictator from the eastern city of Kamakura with the emperor of Japan and his Imperial Court in the official capital city of Heian-kyō (Kyoto) as figureheads. The Kamakura shōguns were members of the Minamoto clan until 1226, the Fujiwara clan until 1252, and the last six were minor princes of the imperial family. The Hōjō clan were the de facto rulers of Japan as shikken (regent) of the shōgun from 1203. The Kamakura shogunate saw the Jōkyū War in 1221 and the Mongol invasions of Japan under Kublai Khan in 1274 and 1281. The Kamakura shogunate was overthrown in the Kenmu Restoration under Emperor Go-Daigo in 1333, re-establishing Imperial rule until Ashikaga Takauji and his offspring overthrew the imperial government and founded the Ashikaga shogunate in 1336 (Nanboku-chō period).

A magnate is a man from the higher nobility, a man who belongs to the high office-holders, or a man in a high social position, by birth, wealth or other qualities in Western Christian countries since the medieval period. It also includes the members of the higher clergy, such as bishops, archbishops and cardinals. In reference to the medieval, the term is often used to distinguish higher territorial landowners and warlords, such as counts, earls, dukes, and territorial-princes from the baronage. In Poland the szlachta (nobles) constituted one of the largest proportions of the population (around 10-12%) and 'magnat' refers to the richest nobles, or nobles of the nobility - even though they had equal voting rights in Poland's electoral monarchy.

Simeon I the Great (Church Slavonic: цѣсар҄ь Сѷмеѡ́нъ А҃ Вели́къ; Bulgarian: цар Симеон I Велики, romanized: Simeon I Veliki [simɛˈɔn ˈpɤrvi vɛˈliki]; Greek: Συμεών Αʹ ὁ Μέγας, romanized: Sumeṓn prôtos ho Mégas) ruled over Bulgaria from 893 to 927, during the First Bulgarian Empire. Simeon's successful campaigns against the Byzantines, Magyars and Serbs led Bulgaria to its greatest territorial expansion ever, making it the most powerful state in contemporary Eastern and Southeast Europe. His reign was also a period of unmatched cultural prosperity and enlightenment later deemed the Golden Age of Bulgarian culture.

During Simeon's rule, Bulgaria spread over a territory between the Aegean, the Adriatic and the Black seas. The newly independent Bulgarian Orthodox Church became the first new patriarchate besides the Pentarchy, and Bulgarian Glagolitic and Cyrillic translations of Christian texts spread all over the Slavic world of the time. It was at the Preslav Literary School in the 890s that the Cyrillic alphabet was developed. Halfway through his reign, Simeon assumed the title of "emperor" (Tsar), having prior to that been styled "prince" (Knyaz).

Carol I or Charles I of Romania (born Karl Eitel Friedrich Zephyrinus Ludwig von Hohenzollern-Sigmaringen; 20 April 1839 – 10 October [O.S. 27 September] 1914), nicknamed the King of Independence (Romanian: Regele Independenței), was the monarch of Romania from 1866 to his death in 1914, ruling as Prince (Domnitor) from 1866 to 1881, and as King from 1881 to 1914. He was elected Prince of the Romanian United Principalities on 20 April 1866 after the overthrow of Alexandru Ioan Cuza by a palace coup d'état. In May 1877, Romania was proclaimed an independent and sovereign nation. The defeat of the Ottoman Empire (1878) in the Russo-Turkish War secured Romanian independence, and he was proclaimed King on 26 March [O.S. 14 March] 1881. He was the first ruler of the Hohenzollern-Sigmaringen dynasty, which ruled the country until the proclamation of a socialist republic in 1947.

During his reign, Carol I personally led Romanian troops during the Russo-Turkish War and assumed command of the Russo-Romanian army during the siege of Plevna. The country achieved internationally recognized independence via the Treaty of Berlin, 1878 and acquired Southern Dobruja from Bulgaria in 1913. In 1883 the king entered a top-secret military alliance with the Austro-Hungarian Empire, despite popular demands against Hungary. When World War I broke out he was unable to activate the alliance. Romania remained neutral and in 1916 joined the Allies.

King is a royal title given to a male monarch. A king is an absolute monarch if he holds unrestricted governmental power or exercises full sovereignty over a nation. In a modern context, the title may refer to the ruler of one of a number of modern monarchies (either absolute or constitutional). The title of king is used alongside other titles for monarchs: in the West, emperor, grand prince, prince, archduke, duke or grand duke, and in the Islamic world, malik, sultan, emir or hakim, etc.

The term king may also refer to a king consort, a title that is sometimes given to the husband of a queen regnant, but the title of prince consort is more common.

Princeps (plural: Principes) is a Latin word meaning "first in time or order; the first, foremost, chief, the most eminent, distinguished, or noble; the first person". As a title, Princeps originated in the Roman Republic wherein the leading member of the Senate was designated princeps senatus. It is primarily associated with the Roman emperors as an unofficial title first adopted by Augustus (r. 27 BC – AD 14) in 27 BC. Its use in this context continued until the regime of Diocletian (r. 284–305) at the end of the third century. He preferred the title of dominus, meaning "lord" or "master". As a result, the Roman Empire from Augustus to Diocletian is termed the "principate" (principatus), and from Diocletian on the "dominate" (dominatus). Other historians define the reign of Augustus to Severus Alexander (r. 222–235) as the Principate, and the period afterwards as the "Autocracy".

The medieval title "Prince" goes back to princeps, as does the title Principal.

Poland was ruled at various times either by dukes and princes (10th to 14th centuries) or by kings (11th to 18th centuries). During the latter period, a tradition of free election of monarchs made it a uniquely electable position in Europe (16th to 18th centuries).

The first Polish ruler whose existence is not debatable was Duke Mieszko I, who adopted Christianity under the authority of Rome in the year 966. He was succeeded by his son, Bolesław I the Brave, who greatly expanded the boundaries of the Polish state and ruled as the first king in 1025. The following centuries gave rise to the mighty Piast dynasty, consisting of both kings such as Mieszko II Lambert, Przemysł II or Władysław I the Elbow-high and dukes like Bolesław III Wrymouth. The dynasty's rule over Poland ceased with the death of Casimir III the Great in 1370. In the same year, the Capetian House of Anjou became the ruling house with Louis I as king of both Poland and Hungary. His daughter, Jadwiga, later married Jogaila, the pagan Grand Duke of Lithuania, who in 1386 was baptized and crowned as Władysław II Jagiełło, thus creating the Jagiellonian dynasty and a personal union between Poland and Lithuania.

Emir (/əˈmɪər, eɪˈmɪər, ˈeɪmɪər/; Arabic: أمير ʾamīr [ʔæˈmiːr] (listen), also transliterated as amir, is a word of Arabic origin that can refer to a male monarch, aristocrat, holder of high-ranking military or political office, or other person possessing actual or ceremonial authority. The title has a history of use in West Asia, East Africa, West Africa, Central Asia, and South Asia. In the modern era, when used as a formal monarchical title, it is roughly synonymous with "prince", applicable both to a son of a hereditary monarch, and to a reigning monarch of a sovereign principality, namely an emirate. The feminine form is emira (أميرة ʾamīrah), with the same meaning as "princess".

Prior to its use as a monarchical title, the term "emir" was historically used to denote a "commander", "general", or "leader" (for example, Amir al-Mu'min). In contemporary usage, "emir" is also sometimes used as either an honorary or formal title for the head of an Islamic, or Arab (regardless of religion) organisation or movement.
