A dynastic union is a type of union in which different states are governed beneath the same dynasty, with their boundaries, their laws, and their interests remaining distinct from each other.
It is a form of association looser than a personal union, when several states share the same monarch, and a real union, when they have common institutions in addition to the same monarch.
The Principality of Catalonia was a medieval and early modern state in the northeastern Iberian Peninsula. During most of its history it was in dynastic union with the Kingdom of Aragon, constituting together the Crown of Aragon. Between the 13th and the 18th centuries, it was bordered by the Kingdom of Aragon to the west, the Kingdom of Valencia to the south, the Kingdom of France to the north and by the Mediterranean Sea to the east. Its sovereign or prince had the title of Count of Barcelona. The term Principality of Catalonia was official until the 1830s, when the Spanish government implemented the centralized provincial division, but remained in popular and informal contexts. Today, the term Principat ("Principality") is used primarily to refer to the autonomous community of Catalonia in Spain, as distinct from the other Catalan Countries, and often including the historical region of Roussillon in Southern France.
The first reference to Catalonia and the Catalans appears in the Liber maiolichinus de gestis Pisanorum illustribus, a Pisan chronicle (written between 1117 and 1125) of the conquest of Majorca by a joint force of Northern Italians, Catalans, and Occitans. At the time, Catalonia did not yet exist as a political entity, though the use of this term seems to acknowledge Catalonia as a cultural or geographical entity. The counties that eventually made up the Principality of Catalonia were gradually unified under the rule of the count of Barcelona. In 1137, the County of Barcelona and the Kingdom of Aragon were unified under a single dynasty, creating what modern historians call the Crown of Aragon; however, Aragon and Catalonia retained their own political structure and legal systems, developing separate political communities along the next centuries. Under Alfons I the Troubador (1164–1196), Catalonia was regarded as a legal entity for the first time in 1173. Still, the term Principality of Catalonia was not used legally until the 14th century, when it was applied to the territories ruled by the Courts of Catalonia.
The Kingdom of Sicily (Latin: Regnum Siciliae; Sicilian: Regnu di Sicilia; Italian: Regno di Sicilia) was a state that existed in Sicily and the southern Italian Peninsula as well as, for a time, in Northern Africa, from its founding by Roger II of Sicily in 1130 until 1816. It was a successor state of the County of Sicily, which had been founded in 1071 during the Norman conquest of the southern peninsula. The island was divided into three regions: Val di Mazara, Val Demone and Val di Noto.
After a brief rule by Charles of Anjou, a revolt in 1282 known as the Sicilian Vespers threw off Angevin rule in the island of Sicily. The Angevins managed to maintain control in the mainland part of the kingdom, which became a separate entity also styled Kingdom of Sicily, although it is retroactively referred to as the Kingdom of Naples. The Kingdom of Sicily on the island(also known as Kingdom of Trinacria between 1282 and 1442) on the other hand, remained an independent kingdom ruled by relatives of the House of Barcelona, and was then added permanently to the Crown of Aragon as a result of the Compromise of Caspe of 1412. Following the dynastic union of the crowns of Castile and Aragon in 1479, it was a viceroyalty of the Spanish kingdom. During the War of the Spanish Succession (1700–1714), the island was taken over by the House of Savoy. In 1720, Savoy gave it to Austria in exchange for Sardinia. Later, the island was ruled by a branch of the Bourbons. Following the Napoleonic period, the Kingdom of Sicily was formally merged with the Kingdom of Naples to form the Kingdom of the Two Sicilies, which in 1861 became part of the new unified Kingdom of Italy.
The Crown of Aragon (US: /-ɡɒn/) was a composite monarchy ruled by one king, originated by the dynastic union of the Kingdom of Aragon and the County of Barcelona (later Principality of Catalonia) and ended as a consequence of the War of the Spanish Succession. At the height of its power in the 14th and 15th centuries, the Crown of Aragon was a thalassocracy controlling a large portion of present-day eastern Iberian Peninsula, parts of what is now southern France, and a Mediterranean empire which included the Balearic Islands, Sicily, Corsica, Sardinia, Malta, Southern Italy (from 1442), and parts of Greece (until 1388).
The component realms of the Crown were not united politically except at the level of the king, who ruled over each autonomous state according to its own laws, raising funds under each tax structure, and dealing separately with each Corts or Cortes (parliaments), particularly in the Kingdom of Aragon, the Principality of Catalonia, and the Kingdom of Valencia. The larger Crown of Aragon must not be confused with one of its constituent parts, the Kingdom of Aragon, from which it takes its name.
The Catholic Monarchs were Queen Isabella I of Castile (r. 1474–1504) and King Ferdinand II of Aragon (r. 1479–1516), whose marriage and joint rule marked the de facto unification of Spain. They were both from the House of Trastámara and were second cousins, as they were both descended from John I of Castile. To remove the obstacle that this consanguinity would otherwise have posed to their marriage under canon law, they were given a papal dispensation by Sixtus IV. They married on October 19, 1469, in the city of Valladolid; Isabella was 18 years old and Ferdinand a year younger. Most scholars generally accept that the unification of Spain can essentially be traced back to the marriage of Ferdinand and Isabella. Their reign was called by W.H. Prescott "the most glorious epoch in the annals of Spain."
Spain was formed as a dynastic union of two crowns rather than a unitary state, as Castile and Aragon remained separate kingdoms until the Nueva Planta decrees of 1707–1716. The court of Ferdinand and Isabella was constantly on the move in order to bolster local support for the crown from local feudal lords. The title of "Catholic King and Queen" was officially bestowed on Ferdinand and Isabella by Pope Alexander VI in 1494, in recognition of their defence of the Catholic faith within their realms.
Isabella I (Spanish: Isabel I; 22 April 1451 – 26 November 1504), also called Isabella the Catholic (Spanish: Isabel la Católica), was Queen of Castile and León from 1474 until her death in 1504. She was also Queen of Aragon from 1479 until her death as the wife of King Ferdinand II. Reigning together over a dynastically unified Spain, Isabella and Ferdinand are known as the Catholic Monarchs. Her reign marked the end of Reconquista and also the start of Spanish Empire and dominance of Spain over European politics for the next century.
Isabella's marriage to Ferdinand of Aragon in 1469 created the basis of the de facto unification of Spain. With Ferdinand's help, she won the War of the Castilian Succession, securing her position as Queen of Castille. Isabella reorganized the governmental system, brought the crime rate down, and unburdened the kingdom of the debt which her half-brother King Henry IV had left behind. Her reforms and those she made with her husband had an influence that extended well beyond the borders of their united kingdoms.
Ferdinand II, also known as Ferdinand I, Ferdinand III, and Ferdinand V (10 March 1452 – 23 January 1516), called Ferdinand the Catholic, was King of Aragon from 1479 until his death in 1516. As the husband and co-ruler of Queen Isabella I of Castile, he was also King of Castile from 1475 to 1504 (as Ferdinand V). He reigned jointly with Isabella over a dynastically unified Spain; together they are known as the Catholic Monarchs. Ferdinand is considered the de facto first king of Spain, and was described as such during his reign, even though, legally, Castile and Aragon remained two separate kingdoms until they were formally united by the Nueva Planta decrees issued between 1707 and 1716.
The Crown of Aragon that Ferdinand inherited in 1479 included the kingdoms of Aragon, Valencia, Mallorca, Sardinia, and Sicily, as well as the Principality of Catalonia. His marriage to Isabella is regarded as the "cornerstone in the foundation of the Spanish monarchy". They played a major role in the European colonization of the Americas, sponsoring the first voyage of Christopher Columbus in 1492. That year the couple defeated Granada, the last Muslim state in Western Europe, thus completing the centuries-long Reconquista.
For most of its history, what is today Belgium was either a part of a larger territory, such as the medieval Carolingian Empire, or was divided into a number of smaller states. In the Middle Ages, the territory of present-day Belgium was fragmented into numerous feudal principalities, including the Duchy of Lower Lorraine, the Duchy of Brabant, the County of Flanders, the Prince-Bishopric of Liège, the County of Namur, the County of Hainaut and the County of Luxembourg. Belgium's modern shape can be traced back at least as far as the southern core of the medieval Burgundian Netherlands. The Eighty Years' War (1568–1648) later led to the split between a northern Dutch Republic and the Southern Netherlands from which Belgium and Luxembourg developed. The area, long a Habsburg stronghold, briefly came under Bourbon control during the War of the Spanish Succession. The resulting Peace of Utrecht transferred the area back to Habsburg control, creating what is now known as the Austrian Netherlands. The French Revolutionary wars led to Belgium becoming part of France in 1795. After the defeat of the French in 1814, the Congress of Vienna created two new states, the United Kingdom of the Netherlands and the Grand Duchy of Luxembourg, which were placed in dynastic union under the House of Orange-Nassau. The Southern Netherlands rebelled during the 1830 Belgian Revolution, establishing the modern Belgian state, officially recognized at the London Conference of 1830. The first King of Belgium, Leopold I, assumed the throne in 1831.
The first half of the twentieth century was tumultuous. Its historic neutrality was violated in each of the World Wars. During World War I, frustrated German invaders launched the Rape of Belgium. During the 1940 invasion, the quick surrender by Leopold III of Belgium to German forces drove a wedge between the King and his people. The King's attempt to return led to a constitutional crisis in 1950, which led to his abdication in favor of his son Baudouin. Belgium entered the second half of the twentieth century showing an unprecedented era of economic growth, as Belgium took an active role in the formation of the Benelux customs union with its neighbors. Ultimately, the Benelux union would serve as a model for the European Economic Community, a precursor to the European Union; to this day Brussels serves as the seat of many of the European Union institutions.
The Dutch–Portuguese War was a global armed conflict involving Dutch forces, in the form of the Dutch East India Company (VOC), the Dutch West India Company, and their allies, against the Iberian Union, and after 1640, the Portuguese Empire. Beginning in 1598, the conflict primarily involved the Dutch companies and fleet invading Portuguese colonies in the Americas, Africa, and the East Indies.
The war can be thought of as an extension of the Eighty Years' War being fought in Europe at the time between Spain and the Netherlands, as Portugal was in a dynastic union with Spain after the War of the Portuguese Succession, for most of the conflict. However, the conflict had little to do with the war in Europe and served mainly as a way for the Dutch to gain an overseas empire and control trade at the cost of the Portuguese. Because of the commodity at the center of the conflict, this war would be nicknamed the Spice War.
