The political history of France covers the history of political movements and systems of government in the nation of France, from the earliest stages of the history of France until the present day. This political history might be considered to start with the formation of the Kingdom of France, and continue until the present day. Political history is the narrative and survey of political events, ideas, movements, organs of government, voters, parties and leaders. It is closely related to other fields of history, including diplomatic history, constitutional history, social history, people's history, and public history. Political history studies the organization and operation of power in large societies. 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 colonies in Asia and Africa, and the largest being New France in North America. 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 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).
