Hugh Capet in the context of "Hugh the Great"

The Kingdom of France is the historiographical name or umbrella term given to various political entities of France in the medieval and early modern period. It was one of the most powerful states in Europe from the High Middle Ages to 1848 during its dissolution. It was also an early colonial power, with colonies in Asia and Africa, and the largest being New France in North America geographically centred on the Great Lakes.

The Kingdom of France was descended directly from the western Frankish realm of the Carolingian Empire, which was ceded to Charles the Bald with the Treaty of Verdun (843). A branch of the Carolingian dynasty continued to rule until 987, when Hugh Capet was elected king and founded the Capetian dynasty. The territory remained known as Francia and its ruler as rex Francorum ('king of the Franks') well into the High Middle Ages. The first king calling himself rex Francie ('King of France') was Philip II, in 1190, and officially from 1204. From then, France was continuously ruled by the Capetians and their cadet lines under the Valois and Bourbon until the monarchy was abolished in 1792 during the French Revolution. The Kingdom of France was also ruled in personal union with the Kingdom of Navarre over two time periods, 1284–1328 and 1572–1620, after which the institutions of Navarre were abolished and it was fully annexed by France (though the King of France continued to use the title "King of Navarre" through the end of the monarchy).

The Capetian dynasty (/kəˈpiːʃən/ kə-PEE-shən; French: Capétiens/ka.pe.sjɛ̃/), also known as the House of France (French: La Maison de France), is a dynasty of Frankish origin, and a branch of the Robertians agnatically, and the Carolingians through female lines. 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 from the House of Capet ruled in France from the election of Hugh Capet in 987 until the death of Charles IV in 1328. That line was succeeded by cadet branches, first the House of Valois, and succeeding them the House of Bourbon, which ruled until the French Revolution abolished the monarchy in 1792 and tried and executed King Louis XVI in 1793. 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, a cadet branch of the Bourbons. Cadet branches of the Capetian House of Bourbon are still reigning over Spain and Luxembourg.

The dynasty had a crucial role in the formation of the French state. From a power base initially confined to their own demesne, the Île-de-France, the Capetian kings slowly but steadily increased their power and influence until it grew to cover the entirety of their realm. For a detailed narration on the growth of French royal power, see Crown lands of France. Members of the dynasty were traditionally Catholic, and the early Capetians had an alliance with the Church. The French were also the most active participants in the Crusades, culminating in a series of five Crusader kings – Louis VII, Philip Augustus, Louis VIII, Louis IX, and Philip III. The Capetian alliance with the papacy suffered a severe blow after the disaster of the Aragonese Crusade. Philip III's son and successor, Philip IV, arrested Pope Boniface VIII and brought the papacy under French control. The later Valois, starting with Francis I, ignored religious differences and allied with the Ottoman sultan to counter the growing power of the Holy Roman Empire. Henry IV was a Protestant at the time of his accession, but realized the necessity of conversion after four years of religious warfare.

The title Duke (and Prince) of the Franks (Latin: dux (et princeps) Francorum) has been used for three different offices, always with "duke" implying military command and "prince" implying something approaching sovereign or regalian rights. The term "Franks" may refer to an ethnic group or to the inhabitants of a territory called Francia.

The first office was that of the mayors of the palace of the Merovingian kings of the Franks, whose powers increased as those of the kings declined. The second was that of the second-in-command to the early kings of France, the last incumbent of which succeeded to the throne in 987. This title was sometimes rendered as Duke of France (dux Franciae). The third instance was that of the rulers in East Francia (now Germany) of the so-called "tribal" duchy of Franconia.

Robert the Strong (French: Robert le Fort; c. 830 – 866) was the father of two kings of West Francia: Odo (or Eudes) and Robert I of France. His family is named after him and called the Robertians. In 853, he was named missus dominicus by Charles the Bald, King of West Francia. Robert the Strong was the great-grandfather of Hugh Capet and thus the ancestor of all the Capetians.

The Robertians (sometimes called the Robertines in modern scholarship) are a proposed Frankish noble family and royal dynasty, whose members were ancestors of the Capetian dynasty that ruled over the Kingdom of France and several other countries (currently Spain and Luxembourg). Prominent Robertian ancestors of the Capetian dynasty appear in historical records as powerful nobles serving under various rulers of the Carolingian dynasty, mainly in West Francia, which later became France. Most notable of them were: the eponymous count Robert the Strong (d. 866) and his sons, West Frankish kings Odo (888–898) and Robert I (922–923), whose son – duke Hugh the Great was father to the first Capetian king Hugh Capet (987–996).

The House of Orléans (French: Maison d'Orléans), sometimes called the House of Bourbon-Orléans (French: Maison de Bourbon-Orléans) to distinguish it, is the fourth holder of a surname previously used by several branches of the Royal House of France, all descended in the legitimate male line from the dynasty's founder, Hugh Capet. The house was founded by Philippe I, Duke of Orléans, younger son of Louis XIII and younger brother of Louis XIV, the "Sun King".

From 1709 until the French Revolution, the Orléans dukes were next in the order of succession to the French throne after members of the senior branch of the House of Bourbon, descended from Louis XIV. Although Louis XIV's direct descendants retained the throne, his brother Philippe's descendants flourished until the end of the French monarchy. The Orléanists held the French throne from 1830 to 1848 and are still pretenders to the French throne today.
