Realm in the context of "Monarchies in Europe"

A polity is a group of people with a collective identity, who are organized by some form of political, institutionalized, social relations, and have a capacity to mobilize resources. It is the unit or entity of a political community or body politic.

A polity can be any group of people organized for governance, such as by the board of a corporation, and in the case of a federal country, the government that exists at both its federal level and the level of its subdivided regions. A polity may have various forms, such as a republic administered by an elected representative, a realm of a hereditary monarch, an incorporated city managed by an appointed mayor, and many others.

A cadet branch consists of the male-line descendants of a monarch's, ruler's or patriarch's younger sons (cadets). In the ruling dynasties and noble families of much of Europe and Asia, the family's major assets (realm, titles, fiefs, properties, lands and income) have historically been passed from the father to his firstborn son in what is known as primogeniture; younger sons, the cadets, generally inherited less wealth and authority (such as a small appanage) to pass on to future generations of their descendants.

In families and cultures in which that was not the custom or law, such as the feudal Holy Roman Empire, the equal distribution of the family's holdings among male members was eventually apt to so fragment the inheritance as to render it too small to sustain the descendants at the socio-economic level of their forefather—and indeed, too small to efficiently manage or effectively defend. Moreover, brothers and their descendants sometimes quarreled over their allocations, or even became estranged. While agnatic primogeniture became a common way of keeping the family's wealth intact and reducing familial disputes, it did so at the expense of younger sons and their descendants. Both before and after a state legal default of inheritance by primogeniture, younger brothers sometimes vied with older brothers to be chosen as their father's heir or, after the choice was made, sought to usurp the elder's birthright.

The unification of the Georgian realm (Georgian: ქართული სახელმწიფოს გაერთიანება, romanized: kartuli sakhelmts'ipos gaertianeba) was the 10th-century political movement that resulted in the consolidation of various Georgian crowns into a single realm with centralized government in 1008, the Kingdom of Georgia, or Sakartvelo. It was originally initiated by the powerful local aristocracy of the eristavs, due to centuries-long power struggles and aggressive wars of succession between the Georgian monarchs, arising from their independent ruling traditions of classical antiquity and their Hellenistic-era monarchical establishments in Colchis and Iberia.

The initiative was supported by David III the Great of the Bagrationi dynasty, the most powerful ruler in the Caucasus at the time, who would put prince royal Bagrat, his kin and foster-son, on the Iberian throne, who would eventually be crowned King of all-Georgia. David's Bagratid successors would become the champions of national unification, just like the Rurikids or the Capetians, but despite their enthusiasm, some of the Georgian polities that had been targeted for unification did not join the unification freely and would actively fight against it throughout this process, mostly seeking help and support from the Byzantine Empire and the Abbasid Caliphate. Even though the 1008 unification of the realm would unite most of western and central Georgian lands, the process would continue to the east, and eventually reach its total completion under King David IV the Builder. This unprecedented political unification of lands and the meteoric rise of Bagrationi power would inaugurate the Georgian Golden Age and creation of the only medieval pan-Caucasian empire, attaining its greatest geographical extent and dominating the entire Caucasus in the 11th, 12th and 13th centuries.

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.

The Mahājanapadas were sixteen kingdoms and aristocratic republics that existed in ancient India from the sixth to fourth centuries BCE, during the second urbanisation period.

The Realm of New Zealand is the area over which the monarch of New Zealand is head of state. The realm is not a federation but is a collection of states and territories united under its monarch. New Zealand is an independent and sovereign state that has one territorial claim in Antarctica (the Ross Dependency), one dependent territory (Tokelau), and two associated states (the Cook Islands and Niue). The Realm of New Zealand encompasses the three autonomous jurisdictions of New Zealand, the Cook Islands, and Niue.

The Ross Dependency has no permanent inhabitants, while Tokelau, the Cook Islands and Niue have indigenous populations. The United Nations formally classifies Tokelau as a non-self-governing territory; the Cook Islands and Niue are self-governing. The governor-general of New Zealand represents the monarch throughout the Realm of New Zealand, though the Cook Islands have an additional king's representative.
