House of Burgundy in the context of "Berengaria of Portugal"

The Heracleidae (/hɛrəˈklaɪdiː/; Ancient Greek: Ἡρακλεῖδαι) or Heraclids /ˈhɛrəklɪdz/ were the numerous descendants of Heracles, especially applied in a narrower sense to the descendants of Hyllus, the eldest of his four sons by Deianira (Hyllus was also sometimes thought of as Heracles' son by Melite). Other Heracleidae included Macaria, Lamos, Manto, Bianor, Tlepolemus, and Telephus. These Heraclids were a group of Dorian kings who conquered the Peloponnesian kingdoms of Mycenae, Sparta and Argos; according to the literary tradition in Greek mythology, they claimed a right to rule through their ancestor. Since Karl Otfried Müller's Die Dorier (1830, English translation 1839), I. ch. 3, their rise to dominance has been associated with a "Dorian invasion". Though details of genealogy differ from one ancient author to another, the cultural significance of the mythic theme, that the descendants of Heracles, exiled after his death, returned some generations later to reclaim land that their ancestors had held in Mycenaean Greece, was to assert the primal legitimacy of a traditional ruling clan that traced its origin, thus its legitimacy, to Heracles.

In the historical period, several dynasties claimed descent from Heracles, such as the Agiads and Eurypontids of Sparta, or the Temenids of Macedonia. In modern times, the same lineage has been claimed by the House of Burgundy and the kings of Castile.

Duke of Burgundy (French: duc de Bourgogne) was a title used by the rulers of the Duchy of Burgundy, from its establishment in 843 to its annexation by the French crown in 1477, and later by members of the House of Habsburg, including Holy Roman Emperors and kings of Spain, who claimed Burgundy proper and ruled the Burgundian Netherlands.

The Duchy of Burgundy was a small portion of the traditional lands of the Burgundians west of the river Saône which, in 843, was allotted to Charles the Bald's kingdom of the West Franks. Under the Ancien Régime, the duke of Burgundy was the premier lay peer of the Kingdom of France. Beginning with Robert II of France (r. 996–1031), the title was held by the Capetians, the French royal family. In 1032 King Henry I of France granted the duchy to his younger brother, Robert, who founded the House of Burgundy. When the senior line of the House of Burgundy became extinct in 1361, the title was inherited by King John II of France through proximity of blood. John granted the duchy to his younger son, Philip the Bold, in 1363. The Valois dukes gradually came to rule over a vast complex of territories known as the Burgundian State, and became dangerous rivals to the senior French royal line of the House of Valois.

Burgundy (/ˈbɜːrɡəndi/ BUR-gən-dee, French: Bourgogne [buʁɡɔɲ] ; Burgundian: Bregogne) is a historical region in France, encompassing the territory of the former administrative region of the same name, that existed from 1982 to 2015, and was merged since 1 January 2016 into the newly created administrative region of Bourgogne-Franche-Comté, encompassing its western half. In historical terms, that region was formed as the Duchy of Burgundy, which existed between the 10th and the 18th century. During the late medieval and early modern periods, the region was of great political importance, being the core of the Valois-Burgundian State, and also becoming a focal point of diplomacy and courtly culture that set the fashion for European royal houses and their courts. The regional capital, Dijon, was wealthy and powerful, being a major European centre of art and science, and of Western Monasticism.

The modern Burgundy encompasses only the north-western parts of the ancient Kingdom of the Burgundians, that had much wider territorial scope. In 843, under the Treaty of Verdun, old Burgundian lands were divided, with all of north-western regions being assigned to the West Frankish Kingdom. Since the beginning of the 10th century, those regions were organized as the Duchy of Burgundy, remaining under the sovereignty of the Kingdom of France. Since 1004, the House of Burgundy, a cadet branch of the French royal House of Capet, ruled over the Duchy, that roughly conformed to the borders and territories of the later administrative region of Burgundy. Upon the extinction of the Burgundian male line the duchy reverted to the King of France and the House of Valois.

The Duchy of Burgundy (/ˈbɜːrɡəndi/; Latin: Ducatus Burgundiae; French: Duché de Bourgogne) was a medieval and early modern feudal polity in north-western regions of historical Burgundy. It was a duchy, ruled by dukes of Burgundy. The Duchy belonged to the Kingdom of France, and was initially bordering the Kingdom of Burgundy to the east and south, thus being distinct from the neighboring Free County of Burgundy (modern region of Franche-Comté). The first duke of Burgundy (Latin: dux Burgundiae), attested in sources by that title, was Richard the Justiciar in 918.

In 1004, prince Henry of France, a son of king Robert II of France, inherited the Duchy, but later ceded it to his younger brother Robert in 1032. Robert became the ancestor of the ducal House of Burgundy, a cadet branch of the royal Capet dynasty, ruling over a territory that roughly conformed to the borders and territories of the modern region of Burgundy (Bourgogne). Upon the extinction of the Burgundian male line with the death of Duke Philip I in 1361, the duchy reverted to King John II of France and the royal House of Valois. The Burgundian duchy was absorbed in a larger territorial complex after 1363, when King John II ceded the duchy to his younger son Philip. With his marriage with Countess Margaret III of Flanders, he laid the foundation for a Burgundian State which expanded further north in the Low Countries collectively known as the Burgundian Netherlands. Upon further acquisitions of the County of Burgundy, Holland, and Luxemburg, the House of Valois-Burgundy came into possession of numerous French and imperial fiefs stretching from the western Alps to the North Sea, in some ways reminiscent of the Middle Frankish realm of Lotharingia.

The House of Valois-Burgundy (French: Maison de Valois-Bourgogne, Dutch: Huis van Valois-Bourgondië), or the Younger House of Burgundy, was a noble French family deriving from the royal House of Valois. (It is distinct from the Capetian House of Burgundy, descendants of King Robert II of France, though both houses stem from the Capetian dynasty.) The Valois-Burgundy family ruled the Duchy of Burgundy from 1363 to 1482 and eventually came to rule vast lands including Artois, Flanders, Luxembourg, Hainault, the county palatine of Burgundy (Franche-Comté), and other lands through marriage, forming what is now known as the Burgundian State.

The term "Valois Dukes of Burgundy" is employed to refer to the dynasty which began after King John II of France granted the French Duchy of Burgundy to his youngest son, Philip the Bold in 1363.

The Battle of Ourique (Arabic: معركة أوريكه) took place on 25 July 1139, in which the forces of Portuguese count Afonso Henriques (of the House of Burgundy) defeated those led by the Almoravid governor of Córdoba, Muhammad Az-Zubayr Ibn Umar, identified as "King Ismar" in Christian chronicles.
