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.[1]

The Catholic Monarchs and Christopher Columbus, 1493

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.

Historical examples

edit

Aragon and Navarre

edit

With the assassination of Sancho IV, Navarre was invaded by his cousins Alfonso VI of Castile and Sancho V Ramirez of Aragon, and the latter was made king in 1076, which led to more than half a century (1076–1134) of Aragonese control.

Aragon and Barcelona

edit

Marriage of Count of Barcelona Raymond Berengar IV of Barcelona and future Queen of Aragon Petronila of Aragon in 1137 that formed the Crown of Aragon.[2][3]

Spain (Castile and Aragon)

edit

Marriage of Isabella I of Castile and Ferdinand II of Aragon in 1469 that laid the foundations for the kingdom of Spain. They did not ascend to their respective thrones until 1474 and 1479 respectively.[4]

Spain and Portugal (Iberian Union)

edit

Dynastic union between Spain (the union between the Crowns of Castile and Aragon) and Portugal (1580–1640),[5] generally called the Iberian Union by modern historians, under the Philippine Dynasty.

Lithuania and Poland

edit

Marriage of Jogaila and Queen Jadwiga of Poland on 1385, generally called the Union of Krewo. That union laid the foundations for the eventual formation of the Polish–Lithuanian Commonwealth.

France and Navarre

edit

Following Salic law, Henry III, King of Navarre, a member of the House of Bourbon, succeeded to the French throne in 1589 upon the extinction of the male line of the House of Valois. Both houses were cadet branches of the Capetian dynasty, the ruling house of the kingdom of France since 987.

Scotland and France

edit

Norman or French culture first gained a foothold in Scotland during the Davidian Revolution, when King David I introduced Continental-style reforms throughout all aspects of Scottish life: social, religious, economic and administrative. He also invited immigrant French and Anglo-French peoples to Scotland. This effectively created a Franco-Scottish aristocracy, with ties to the French aristocracy as well as many to the Franco-English aristocracy. From the Wars of Scottish Independence, as common enemies of England and its ruling House of Plantagenet, Scotland and France started to enjoy a close diplomatic relationship, the Auld Alliance, from 1295 to 1560. From the Late Middle Ages and into the Early Modern Period Scotland and its burghs also benefited from close economic and trading links with France in addition to its links to the Low Countries, Scandinavia and the Baltic.

The prospect of dynastic union came in the 15th and 16th centuries, when Margaret, eldest daughter of James I of Scotland, married the future Louis XI of France. James V of Scotland married two French brides in succession. His infant daughter, Mary I, succeeded him on his death in 1542. For many years thereafter the country was ruled under a regency led by her French mother, Mary of Guise, who succeeded in marrying her daughter to the future Francis II of France. The young couple were king and queen of France and Scotland from 1559 until Francis died in 1560. Mary returned to a Scotland heaving with political revolt and religious revolution, which made a continuation of the alliance impossible.

Cordial economic and cultural relations did continue however, although throughout the 17th century, the Scottish establishment became increasingly Presbyterian, often belligerent to Catholicism, a facet which was somewhat at odds with Louis XIV's aggressively Catholic foreign and domestic policy. The relationship was further weakened by the Union of the Crowns in 1603, which meant from then on that although still independent, executive power in the Scottish government, the Crown, was shared with the Kingdom of England and Scottish foreign policy came into line more with that of England than with France.

England and Scotland

edit

When Elizabeth I of England died in 1603, the heir to the English throne was King James VI of Scotland. Generally called the Union of the Crowns, this dynastic union was in place from 1603 until 1653 (when the monarchy was officially abolished) and again from 1659 until the two nations were politically united in 1707.

United Kingdom and Hanover

edit
 
Portrait of William IV by Martin Archer Shee, 1833. William IV was the last monarch to rule both Britain and Hanover.

The personal union between the United Kingdom of Great Britain and Ireland and the Kingdom of Hanover, jointly ruled by the head of the House of Hanover since 1707, ended with the death of William IV in 1837, and was replaced with a dynastic union: due to the different laws of succession, he was succeeded by two members of the dynasty, in the United Kingdom by his niece Victoria, the daughter of his late next brother Prince Edward, Duke of Kent and Strathearn, and in Hanover by his second next brother Ernest Augustus. This lasted until the annexation of Hanover by Prussia in 1866.
