A succession crisis is a crisis that arises when an order of succession fails, for example when a monarch dies without an indisputable heir. It may result in a war of succession.
Examples include (see List of wars of succession):
The Capetian dynasty, also known as the "House of France", is a dynasty of Frankish origin, and a branch of the Robertians. It is among the largest and oldest royal houses in Europe and the world, and consists of Hugh Capet, the founder of the dynasty, and his male-line descendants, who ruled in France without interruption from 987 to 1792, and again from 1814 to 1848. The senior line ruled in France as the House of Capet from the election of Hugh Capet in 987 until the death of Charles IV in 1328. That line was succeeded by cadet branches, the Houses of Valois and then Bourbon, which ruled without interruption until the French Revolution abolished the monarchy in 1792. The Bourbons were restored in 1814 in the aftermath of Napoleon's defeat, but had to vacate the throne again in 1830 in favor of the last Capetian monarch of France, Louis Philippe I, who belonged to the House of Orléans. Cadet branches of the Capetian House of Bourbon house are still reigning over Spain and Luxembourg.
D. Nuno Álvares Pereira, OCarm was a Portuguese general of great success who had a decisive role in the 1383-1385 Crisis that assured Portugal's independence from Castile. He later became a mystic and was beatified by Pope Benedict XV, in 1918, and canonised by Pope Benedict XVI in 2009.
John I, also called John of Aviz, was King of Portugal from 1385 until his death in 1433. He is recognized chiefly for his role in Portugal's victory in a succession war with Castile, preserving his country's independence and establishing the Aviz dynasty on the Portuguese throne. His long reign of 48 years, the most extensive of all Portuguese monarchs, saw the beginning of Portugal's overseas expansion. John's well-remembered reign in his country earned him the epithet of Fond Memory ; he was also referred to as "the Good", sometimes "the Great", and more rarely, especially in Spain, as "the Bastard" (Bastardo).
Ferdinand I, sometimes called the Handsome or occasionally the Inconstant, was the King of Portugal from 1367 until his death in 1383. His death led to the 1383–85 crisis, also known as the Portuguese interregnum.
An heir presumptive is the person entitled to inherit a throne, peerage, or other hereditary honour, but whose position can be displaced by the birth of a person with a better claim to the position in question. This is in contrast to heirs apparent, whose claim on the position cannot be displaced in this manner.
Henry, dubbed the Chaste and the Cardinal-King, was king of Portugal and a cardinal of the Catholic Church, who ruled Portugal between 1578 and 1580. As a clergyman, he was bound to celibacy, and as such, had no children to succeed him, and thus put an end to the reigning House of Aviz. His death led to the Portuguese succession crisis of 1580 and ultimately to the 60-year Iberian Union that saw Portugal share a monarch with Habsburg Spain. The next independent monarch of Portugal would be John IV, who restored the throne after 60 years of Spanish rule.
An interregnum is a period of discontinuity or "gap" in a government, organization, or social order. Archetypally, it was the period of time between the reign of one monarch and the next, and the concepts of interregnum and regency therefore overlap. Historically, longer and heavier interregna have been typically accompanied by widespread unrest, civil and succession wars between warlords, and power vacuums filled by foreign invasions or the emergence of a new power. A failed state is usually in interregnum.
A personal union is the combination of two or more states that have the same monarch while their boundaries, laws, and interests remain distinct. A real union, by contrast, would involve the constituent states being to some extent interlinked, such as by sharing some limited governmental institutions. Unlike the personal union, in a federation and a unitary state, a central (federal) government spanning all member states exists, with the degree of self-governance distinguishing the two. The ruler in a personal union does not need to be a hereditary monarch.
The House of Aviz, also known as the Joanine Dynasty, was a dynasty of Portuguese origin which flourished during the Renaissance and the period of the Portuguese discoveries, when Portugal expanded its power globally.
Spanish–Portuguese War may refer to one of the following conflicts between Portugal and Spain :
Emmanuel Philibert, known as Testa di ferro, was Duke of Savoy and ruler of the Savoyard states from 1553 to 1580. He is remembered for the recovery of the Savoyard state following the Battle of St. Quentin (1557), and for moving its capital to Turin.
The House of Farnese was an influential family in Renaissance Italy. The titles of Duke of Parma and Piacenza and Duke of Castro were held by various members of the family.
António, Prior of Crato, was a grandson of King Manuel I of Portugal who claimed the Portuguese throne during the 1580 dynastic crisis. According to some historians, he was king of Portugal for 33 days in 1580. Philip II of Spain prevailed in the succession struggle, but António claimed the throne until 1583. He was a disciple of Bartholomew of Braga.
The Portuguese succession crisis of 1580 came about as a result of the deaths of young King Sebastian I of Portugal in the Battle of Alcácer Quibir in 1578 and his successor and great-uncle Henry I in 1580. As Sebastian and Henry had no immediate heirs, these events prompted a dynastic crisis, with internal and external battles between several pretenders to the Portuguese throne. Because Sebastian's body was never found, several impostors emerged over several years claiming to be the young king, further confusing the situation. Ultimately, Philip II of Spain gained control of the country, uniting the Portuguese and Spanish Crowns in the Iberian Union, a personal union that endured 60 years, during which time the Portuguese Empire declined, being challenged globally during the Dutch–Portuguese War.
A war of succession is a war prompted by a succession crisis in which two or more individuals claim the right of successor to a deceased or deposed monarch. The rivals are typically supported by factions within the royal court. Foreign powers sometimes intervene, allying themselves with a faction. This may widen the war into one between those powers.
João das Regras, in English, literally John of the Rules, was a Portuguese jurist of the second half of the 14th century. In the context of the 1383—1385 Crisis, in Portugal, he stood out for his masterly representation for the cause of the Master of Avis in the Coimbra Courts of 1385, the corollary of which was his acclaim as King of Portugal.
In the Medieval Kingdom of Portugal, the Cortes was an assembly of representatives of the estates of the realm – the nobility, clergy and bourgeoisie. It was called and dismissed by the King of Portugal at will, at a place of his choosing. Cortes which brought all three estates together are sometimes distinguished as Cortes-Gerais, in contrast to smaller assemblies which brought only one or two estates, to negotiate a specific point relevant only to them.
The Fernandine Wars were a series of three conflicts between the Kingdom of Portugal under King Ferdinand I and the Crown of Castile under Kings Henry II and later John I. They were fought over Ferdinand's claim to the Castilian succession after the murder of King Peter of Castile in 1369.
A princely rebellion or princely revolt is an intrastate armed conflict by a prince against a reigning monarch of his own family, the ruling dynasty. A prince may rebel against a well-established monarch in order to seize the throne for himself immediately, to ensure his supposed right to sit on the throne in the future, or to secure other rights, privileges or interests such as appanages, alliances or sources of revenue that the monarch allegedly encroached upon, or failed to deliver or guarantee.
