The monarchs of France ruled, first as kings and later as emperors, from the Middle Ages to 1870. There is some disagreement as to when France came into existence. The earliest date would be the establishment of the Merovingian Frankish kingdom by Clovis I in 486 with the defeat of Syagrius, the last Roman official in Gaul. That kingdom's rulers were deposed in the 8th century. The Treaty of Verdun established the Kingdom of Western Francia in 843. Another date favored by many medieval historians is 987, the beginning of the Capetian Dynasty, and of rule by the Direct Capetians.
However, the relevance of such traditional outlooks on the origins of modern nations is historically dubious (see below for recent studies). In light of these recent trends, this list begins with Charles the Bald and the Kingdom of Western Francia, originating in 843, the state which would directly evolve into modern France. For earlier Frankish monarchs, see List of Frankish Kings.
In addition to the monarchs listed below, the Kings of England and Great Britain from 1340-1360 and 1369-1801 also claimed the title of King of France. For a short time, this had some basis in fact - under the terms of the 1420 Treaty of Troyes, Charles VI had recognized his son-in-law Henry V of England as regent and heir. Henry V predeceased Charles VI and so his son, Henry VI, succeeded his grandfather as King of France. Most of Northern France was under English control until 1435, but by 1453, the English had been expelled from all of France save Calais (and the Channel Islands), and Calais itself fell in 1558. Nevertheless, English monarchs continued to claim the title until the creation of the United Kingdom in 1801. Various English kings between 1337 and 1422 had also claimed the title of King of France, but only intermittently.
The title "King of the Franks" (Latin: Rex Francorum) remained in use until the reign of Philip IV. During the brief period when the French Constitution of 1791 was in effect (1791-1792) and after the July Revolution in 1830, the style "King of the French" was used instead of "King of France (and Navarre)". It was a constitutional innovation known as popular monarchy which linked the monarch's title to the people, not to the territory of France.
The name of France comes from the Germanic tribe known as the Franks. The Merovingian kings began as mere chieftains, the oldest known being Pharamond. Clovis I was the first of these to rise to true kingship. After his death, his kingdom was split between his sons into Soissons (Neustria), Paris, Orleans (Burgundy), and Metz (Austrasia). Various other kingdoms would continue to break apart and be formed as the various Merovingian kings warred with each other.
The Carolingians overpowered the Merovingian kings. First they became their majordomos (mayor of the palace) in Austrasia. Eventually, they united the entire Frankish kingdom for the first time since Clovis. With Mayor Pippin the Younger, the Merovingians were completely phased out. The Carolingian Dynasty would be the first true French monarchy. The great and extended kingdom of Pippin's son, the legendary Charlemagne (Charles I), was split by Louis I (Louis the Pious). In 843, while Louis's son Lothair was in power, the great Frankish kingdom was split. The Eastern Kingdom became Germany, the Middle Kingdom became Lotharingia and later part of the Holy Roman Empire, and the Western Kingdom became France. Charles the Bald was the first ruler of the independent West Franks (France).
