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 since the High Middle Ages. It was also an early colonial power, with possessions around the world. France originated as West Francia (Francia Occidentalis), the western half of the Carolingian Empire, 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—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). France in the Middle Ages was a de-centralised, feudal monarchy. In Brittany and Catalonia (now a part of Spain), as well as Aquitaine, the authority of the French king was barely felt. Lorraine and Provence were states of the Holy Roman Empire and not yet a part of France. Initially, West Frankish kings were elected by the secular and ecclesiastic magnates, but the regular coronation of the eldest son of the reigning king during his father's lifetime established the principle of male primogeniture, which became codified in the Salic law. During the Late Middle Ages, rivalry between the Capetian Dynasty, rulers of the Kingdom of France and their vassals the House of Plantagenet, who also ruled the Kingdom of England as part of their so-called competing Angevin Empire, resulted in many armed struggles. The most notorious of them all are the series of conflicts known as the Hundred Years' War (1337–1453) in which the kings of England laid claim to the French throne. Emerging victorious from said conflicts, France subsequently sought to extend its influence into Italy, but was defeated
