Carolingian Empire in the context of "Duchy of Croatia"

In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, comparable with the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages.

Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in Late antiquity (c. ~3rd–8th centuries) and into the Early Middle Ages (c. 5th–10th centuries). The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—once part of the Byzantine Empire—came under the rule of the Umayyad Caliphate, an Islamic empire, after conquest by Muhammad's successors. Although there were substantial changes in society and political structures, the break with classical antiquity was incomplete. The still-sizeable Byzantine Empire, Rome's direct continuation, survived in the Eastern Mediterranean and remained a major power. The empire's law code, the Corpus Juris Civilis or "Code of Justinian", was rediscovered in Northern Italy in the 11th century. In the West, most kingdoms incorporated the few extant Roman institutions. Monasteries were founded as campaigns to Christianise the remaining pagans across Europe continued. The Franks, under the Carolingian dynasty, briefly established the Carolingian Empire during the later 8th and early 9th centuries. It covered much of Western Europe but later succumbed to the pressures of internal civil wars combined with external invasions: Vikings from the north, Magyars from the east, and Saracens from the south.

France, officially the French Republic, is a country primarily located in Western Europe. Its overseas regions and territories include French Guiana in South America, Saint Pierre and Miquelon in the North Atlantic, the French West Indies, and many islands in Oceania and the Indian Ocean, giving it the largest discontiguous exclusive economic zone in the world. Metropolitan France shares borders with Belgium and Luxembourg to the north; Germany to the northeast; Switzerland to the east; Italy and Monaco to the southeast; Andorra and Spain to the south; and a maritime border with the United Kingdom to the northwest. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and the North Sea. Its 18 integral regions—five of which are overseas—span a combined area of 632,702 km (244,288 sq mi) and have an estimated total population of over 68.6 million as of January 2025. France is a semi-presidential republic. Its capital, largest city and main cultural and economic centre is Paris.

Metropolitan France was settled during the Iron Age by Celtic tribes known as Gauls before Rome annexed the area in 51 BC, leading to a distinct Gallo-Roman culture. In the Early Middle Ages, the Franks formed the kingdom of Francia, which became the heartland of the Carolingian Empire. The Treaty of Verdun of 843 partitioned the empire, with West Francia evolving into the Kingdom of France. In the High Middle Ages, France was a powerful but decentralised feudal kingdom, but from the mid-14th to the mid-15th centuries, France was plunged into a dynastic conflict with England known as the Hundred Years' War. In the 16th century French culture flourished during the French Renaissance, and a French colonial empire emerged. Internally, France was dominated by the conflict with the House of Habsburg and the French Wars of Religion between Catholics and Huguenots. France was successful in the Thirty Years' War and further increased its influence during the reign of Louis XIV.

The Carolingian dynasty (/ˌkærəˈlɪndʒiən/ KARR-ə-LIN-jee-ən; known variously as the Carlovingians, Carolingus, Carolings, Karolinger or Karlings) was a Frankish noble family named after Charles Martel and his grandson Charlemagne, descendants of the Arnulfing and Pippinid clans of the 7th century AD. The dynasty consolidated its power in the 8th century, eventually making the offices of mayor of the palace and dux et princeps Francorum hereditary, and becoming the de facto rulers of the Franks as the real powers behind the Merovingian throne. In 751 the Merovingian dynasty which had ruled the Franks was overthrown with the consent of the Papacy and the aristocracy, and Pepin the Short, son of Martel, was crowned king of the Franks. The Carolingian dynasty reached its peak in 800 with the crowning of Charlemagne as the first emperor of the Romans in the West in over three centuries. Charlemagne's death in 814 began an extended period of fragmentation of the Carolingian Empire and decline that would eventually lead to the evolution of the Kingdom of France and the Holy Roman Empire.

The Hungarian invasions of Europe (Hungarian: kalandozások, German: Ungarneinfälle) occurred in the 9th and 10th centuries, during the period of transition in the history of Europe of the Early Middle Ages, when the territory of the former Carolingian Empire was threatened by invasion by the Magyars (Hungarians) from the east, the Viking expansion from the north, and the Arabs from the south.

The Hungarians took possession of the Carpathian Basin (corresponding to the later Kingdom of Hungary) in a planned manner, with a long period of settlement between 862–895, and launched a number of campaigns both westward into former Francia and southward into the Byzantine Empire. The westward raids were stopped only with the Magyar defeat at the Battle of Lechfeld in 955, which led to the revival of the Holy Roman Empire in 962, producing a new political order in Western Europe. The raids into Byzantine territories continued throughout the 10th century, until the eventual Christianisation of the Magyars and the establishment of the Christian Kingdom of Hungary in 1000.

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).

Western civilization traces its roots back to Europe and the Mediterranean. It began in ancient Greece, transformed in ancient Rome, and evolved into medieval Western Christendom before experiencing such seminal developmental episodes as the development of Scholasticism, the Renaissance, the Reformation, the Scientific Revolution, the Enlightenment, the Industrial Revolution, and the development of liberal democracy. The civilizations of classical Greece and Rome are considered seminal periods in Western history. Major cultural contributions also came from the Christianized Germanic peoples, such as the Longobards, the Franks, the Goths, and the Burgundians. Charlemagne founded the Carolingian Empire and he is referred to as the "Father of Europe". Contributions also emerged from pagan peoples of pre-Christian Europe, such as the Celts and Germanic pagans as well as some significant religious contributions derived from Judaism and Hellenistic Judaism stemming back to Second Temple Judea, Galilee, and the early Jewish diaspora; and some other Middle Eastern influences. Western Christianity has played a prominent role in the shaping of Western civilization, which throughout most of its history, has been nearly equivalent to Christian culture. (There were Christians outside of the West, such as China, India, Russia, Byzantium and the Middle East). Western civilization has spread to produce the dominant cultures of modern Americas and Oceania, and has had immense global influence in recent centuries in many ways.

Following the 5th century Fall of Rome, Europe entered the Middle Ages, during which period the Catholic Church filled the power vacuum left in the West by the fall of the Western Roman Empire, while the Eastern Roman Empire (or Byzantine Empire) endured in the East for centuries, becoming a Hellenic Eastern contrast to the Latin West. By the 12th century, Western Europe was experiencing a flowering of art and learning, propelled by the construction of cathedrals, the establishment of medieval universities, and greater contact with the medieval Islamic world via Al-Andalus and Sicily, from where Arabic texts on science and philosophy were translated into Latin. Christian unity was shattered by the Reformation from the 16th century. A merchant class grew out of city states, initially in the Italian peninsula (see Italian city-states), and Europe experienced the Renaissance from the 14th to the 17th century, heralding an age of technological and artistic advance and ushering in the Age of Discovery which saw the rise of such global European empires as those of Portugal and Spain.

Slovenia, officially the Republic of Slovenia, is a country in Central Europe. Formed in 1991, Slovenia borders Italy to the west, Austria to the north, Hungary to the northeast, and Croatia to the south and southeast; its southwestern boundary consists of a 46.6 km coastline on the Adriatic Sea. Slovenia is mostly mountainous and forested, covers 20,271 square kilometres (7,827 sq mi), and has a population of approximately 2.1 million people. Slovene is the official language. Slovenia has a predominantly temperate continental climate, with the exception of the Slovene Littoral and the Julian Alps. Ljubljana, the capital and largest city of Slovenia, is geographically situated near the centre of the country. Other larger urban centers include Maribor, Ptuj, Kranj, Celje, and Koper.

Slovenia's territory has been part of many different states, including the Byzantine Empire, the Carolingian Empire, the Holy Roman Empire, the Kingdom of Hungary, the Republic of Venice, the Illyrian Provinces of Napoleon's First French Empire and the Habsburg Empire. The Kingdom of Serbs, Croats, and Slovenes was formed in December 1918; in 1929, the Kingdom became known as Yugoslavia. In 1946, after World War II, Slovenia was established as one of six republics that made up the socialist federation of Yugoslavia. In June 1991, Slovenia declared independence from Yugoslavia and became an independent sovereign state.

The Catholic Church in France, Gallican Church, or French Catholic Church, is part of the worldwide Catholic Church in communion with the Pope in Rome. Established in the second century in unbroken communion with the bishop of Rome, it is sometimes called the "eldest daughter of the Church" (French: fille aînée de l'Église).

The first written records of Christians in France date from the second century, when Irenaeus detailed the deaths of 90-year-old bishop Saint Pothinus of Lugdunum (Lyon) and other martyrs of the 177 AD persecution in Lyon. In 496 Remigius baptized King Clovis I, who therefore converted from paganism to Catholicism. In 800, Pope Leo III crowned Charlemagne Emperor of the Roman Empire, forming the political and religious foundations of Christendom in Europe and establishing in earnest the French government's long historical association with the Catholic Church. In reaction, the French Revolution (1789–1799) was followed by heavy persecution of the Catholic Church. Since the beginning of the 20th century, Laïcité, absolute neutrality of the state with respect to religious doctrine, is the official policy of the French Republic.
