Agnatic seniority in the context of "Patrilineality"

A hereditary monarchy is a form of government and succession of power in which the throne passes from one member of a ruling family to another member of the same family. A series of rulers from the same family would constitute a dynasty. It is historically the most common type of monarchy and remains the dominant form in extant monarchies.

In most extant hereditary monarchies, the typical order of succession uses some form of primogeniture, but there exist other methods such as seniority and tanistry (in which an heir-apparent is nominated from among qualified candidates). Research shows that hereditary regimes, in particular primogeniture, are more stable than forms of authoritarian rule with alternative succession arrangements.

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).

Feudal fragmentation is a process whereby a feudal state is split into smaller regional state structures, each characterized by significant autonomy, if not outright independence, and ruled by a high-ranking noble such as a prince or a duke. Feudal fragmentation is usually associated with European history, particularly during the Middle Ages.

Feudal fragmentation occurred after the death of the legitimate ruler leaves no clear heirs, and rulers of various subdivisions of the original state fail at electing or agreeing on a new leader for the previous, larger entity. In some cases (for example, the Holy Roman Empire), such a leader may be elected, yet wield much lesser powers than those of his predecessor. Feudal fragmentation is related to the concepts of agnatic seniority and principate.

The monarchies of Malaysia exist in each of the nine Malay states under the constitutional monarchy system as practised in Malaysia. The political system of Malaysia is based on the Westminster parliamentary system in combination with features of a federation.

Nine of the states of Malaysia are constitutionally headed by traditional Malay rulers, collectively referred to as the Malay states. State constitutions limit eligibility for the thrones to male Malay Muslims of royal descent. Seven are hereditary monarchies based on agnatic primogeniture: Kedah, Kelantan, Johor, Perlis, Pahang, Selangor and Terengganu. In Perak, the throne rotates among three branches of the royal family loosely based on agnatic seniority. One state, Negeri Sembilan, is an elective monarchy; the ruler is elected from male members of the royal family by hereditary chiefs. All rulers, except those of Perlis and of Negeri Sembilan, use the title of Sultan. The ruler of Perlis is styled the Raja, whereas the ruler of Negeri Sembilan is known as the Yang di-Pertuan Besar.

The Silesian Piasts were the elder of four lines of the Polish Piast dynasty beginning with Władysław II the Exile (1105–1159), eldest son of Duke Bolesław III of Poland. By Bolesław's testament, Władysław was granted Silesia as his hereditary province and also the Lesser Polish Seniorate Province at Kraków according to the principle of agnatic seniority.

The Distinguished Order of the Golden Fleece (Spanish: Insigne Orden del Toisón de Oro, German: Orden vom Goldenen Vlies) is a Catholic order of chivalry founded in 1430 in Brugge by Philip the Good, Duke of Burgundy, to celebrate his marriage to Isabella of Portugal. Today, two branches of the order exist, namely the Spanish Fleece and the Austrian Fleece; the current grand masters are King Felipe VI of Spain and Karl von Habsburg, head of the House of Habsburg-Lorraine, respectively. The Grand Chaplain of the Austrian branch is Cardinal Christoph Schönborn, Archbishop of Vienna.

The separation of the two existing branches took place as a result of the War of the Spanish Succession of 1701–1714. The grand master of the order, Charles II of Spain (a Habsburg), had died childless in 1700, and so the right to succeed to the throne of Spain (and incidentally to become the Sovereign of the Order of the Golden Fleece) initiated a continental conflict. On one hand, Charles, brother of the Holy Roman Emperor Joseph I, claimed the Spanish crown as an agnatic member of the House of Habsburg, which had inherited the Burgundian titles and had held the Spanish throne for almost two centuries. However, the late king of Spain had named Philip of Bourbon, his sister's grandchild, as his successor in his will. After the conclusion of the war in 1714, the European powers recognized Philip of Bourbon as King of Spain, but the old Burgundian Habsburg territories became the Austrian Netherlands (1714–1797), and with them went the Treasure of the Order and its archive. The two dynasties, the Bourbons of Spain and the Habsburgs of Austria, have ever since continued heading the separate orders of the Golden Fleece.
