Order of succession in the context of "Swedish Act of Succession"

The first written records for the history of France appeared in the Iron Age. What is now France made up the bulk of the region known to the Romans as Gaul. Greek writers noted the presence of three main ethno-linguistic groups in the area: the Gauls, Aquitani and Belgae. Over the first millennium BC the Greeks, Romans and Carthaginians established colonies on the Mediterranean coast and offshore islands. The Roman Republic annexed southern Gaul in the late 2nd century BC, and legions under Julius Caesar conquered the rest of Gaul in the Gallic Wars of 58–51 BC. A Gallo-Roman culture emerged, and Gaul was increasingly integrated into the Roman Empire. In the later stages of the empire, Gaul was subject to barbarian raids and migration. The Frankish king Clovis I united most of Gaul in the late 5th century. Frankish power reached its fullest extent under Charlemagne. The medieval Kingdom of France emerged from the western part of Charlemagne's Carolingian Empire, known as West Francia, and achieved increasing prominence under the rule of the House of Capet, founded in 987.

A succession crisis in 1328 led to the Hundred Years' War between the House of Valois and the House of Plantagenet. The war began in 1337 following Philip VI's attempt to seize the Duchy of Aquitaine from its hereditary holder Edward III of England, the Plantagenet claimant to the French throne. A notable figure of the war was Joan of Arc, a French peasant girl who led forces against the English, establishing herself as a national heroine. The war ended with a Valois victory in 1453, strengthening French nationalism and increasing the power and reach of the French monarchy. During the Ancien Régime over the next centuries, France transformed into a centralized absolute monarchy through the Renaissance and Reformation. At the height of the French Wars of Religion, France became embroiled in another succession crisis, as the last Valois king, Henry III, fought against factions of the House of Bourbon and House of Guise. Henry, the Bourbon King of Navarre, won and established the Bourbon dynasty. A burgeoning worldwide colonial empire was established in the 16th century.

A dynasty is a sequence of rulers from the same family, usually in the context of a monarchical system, but sometimes also appearing in republics. A "house" is a royal or noble family, not always ruling. Historians periodize the histories of many states and civilizations, such as Ireland (10th century), Roman Empire (27 BC – AD 1453), Imperial Iran (678 BC – AD 1979), Ancient Egypt (3100–30 BC), and Ancient and Imperial China (2070 BC – AD 1912), using a framework of successive dynasties. As such, the term "dynasty" may be used to delimit the era during which a family reigned.

Before the 18th century, most dynasties throughout the world were traditionally reckoned patrilineally, such as those that followed the Frankish Salic law. In polities where it was permitted, succession through a daughter usually established a new dynasty in her husband's family name. This has changed in all of Europe's remaining monarchies, where succession law and conventions have maintained dynastic names de jure through a female.

Regicide is the purposeful killing of a monarch and is often associated a violent change in the regime, as in a revolution. A regicide can also be the person responsible for the killing. The word comes from the Latin roots of regis and cida (cidium), meaning "of monarch" and "killer" respectively.In the British tradition, it refers to the judicial execution of a king after a trial, reflecting the historical precedent of the trial and execution of Charles I of England. The concept of regicide has also been explored in media and the arts through pieces like Macbeth (Macbeth's killing of King Duncan).

Scholars have found that regicide is particularly common in political systems with unclear succession rules.

The Osiris myth is the most elaborate and influential story in ancient Egyptian mythology. It concerns the murder of the god Osiris, a primeval king of Egypt, and its consequences. Osiris's murderer, his brother Set, usurps his throne. Meanwhile, Osiris's wife Isis restores her husband's body, allowing him to posthumously conceive their son, Horus. The remainder of the story focuses on Horus, the product of the union of Isis and Osiris, who is at first a vulnerable child protected by his mother and then becomes Set's rival for the throne. Their often violent conflict ends with Horus's triumph, which restores maat (cosmic and social order) to Egypt after Set's unrighteous reign and completes the process of Osiris's resurrection.

The myth, with its complex symbolism, is integral to ancient Egyptian conceptions of kingship and succession, conflict between order and disorder, and especially death and the afterlife. It also expresses the essential character of each of the four deities at its center, and many elements of their worship in ancient Egyptian religion were derived from the myth.

In a monarchy, a regent (from Latin regens 'ruling, governing') is a person appointed to execute the office of the monarch temporarily. Regencies may arise for a number of reasons, including the monarch being a minor, ill, absent from the country, or otherwise unavailable. A regent may also be appointed in cases where the throne is vacant, or the identity of the legitimate monarch is disputed.

The rule of a regent or regents is called a regency. A regent or regency council may be formed as an ad hoc measure, or there may be a formal and regular appointment process. Regent in some countries has also been used as a formal title granted to a monarch's most trusted advisor or personal assistant. If the regent is holding the position due to their being in the line of succession, the compound term prince regent is often used; if the regent of a minor is their mother, and she is wife or widow of a king, she would be referred to as queen regent.

Abdication is the act of formally relinquishing monarchical authority. Abdications have played various roles in the succession procedures of monarchies. While some cultures have viewed abdication as an extreme abandonment of duty, in other societies (such as pre-Meiji Restoration Japan), abdication was a regular event and helped maintain stability during political succession.

Historically, abdications have occurred both by force (where the regnant was dethroned, thus forced to abdicate on pain of death or other severe consequences) and voluntarily. Some rulers are deemed to have abdicated in absentia, vacating the physical throne and thus their position of power, although these judgements were generally pronounced by successors with vested interests in seeing the throne abdicated, and often without or despite the direct input of the abdicating monarch.

An order of precedence is a sequential hierarchy of importance applied to individuals, groups, or organizations. For individuals, it is most often used for diplomats in attendance at very formal occasions. It can also be used in the context of medals, decorations, and awards.

A person's position in an order of precedence is not necessarily an indication of functional importance, but rather an indication of ceremonial or historical relevance; for instance, it may dictate where dignitaries are seated at formal dinners. The term is occasionally used to mean the order of succession—to determine who replaces the head of state in the event they are removed from office or incapacitated—as this order often correlates with importance.

Primogeniture (/ˌpraɪməˈdʒɛnɪtʃər, -oʊ-/) is the right, by law or custom, of the firstborn legitimate child to inherit all or most of their parent's estate, as well as succeed their parent as the ruler of a state.

Primogeniture stands in contrast to shared inheritance among all or some children, any illegitimate child or any collateral relative. In most contexts, it means the inheritance of the firstborn son (agnatic primogeniture). It can also mean by the firstborn daughter (matrilineal primogeniture), or firstborn child (absolute primogeniture).

An heir apparent is a person who is first in the order of succession and cannot be displaced from inheriting by the birth of another person. A person who is first in the current order of succession but could be displaced by the birth of a more eligible heir is known as an heir presumptive.

Today these terms most commonly describe heirs to hereditary titles (e.g. titles of nobility) or offices, especially when only inheritable by a single person. Most monarchies refer to the heir apparent of their thrones with the descriptive term of crown prince or crown princess, but they may also be accorded with a more specific substantive title: such as Prince of Orange in the Netherlands, Duke of Brabant in Belgium, Prince of Asturias in Spain (also granted to heirs presumptive), or the Prince of Wales in England and Wales; former titles include Dauphin in the Kingdom of France, and Tsesarevich in Imperial Russia.
