France

The Jacquerie (French: [ʒakʁi]) was a popular revolt by peasants that took place in northern France in the early summer of 1358 during the Hundred Years' War. The revolt was centred in the valley of the Oise north of Paris and was suppressed after over two months of violence. This rebellion became known as "the Jacquerie" because the nobles derided peasants as "Jacques" or "Jacques Bonhomme" for their padded surplice, called a "jacque". The aristocratic chronicler Jean Froissart and his source, the chronicle of Jean le Bel, referred to the leader of the revolt as Jacque Bonhomme ("Jack Goodfellow"), though in fact the Jacquerie 'great captain' was named Guillaume Cale. The word jacquerie became a synonym of peasant uprisings in general in both English and French.

The Aosta Valley (Italian: Valle d'Aosta [ˈvalle daˈɔsta]; French: Vallée d'Aoste [vale dɔst] ; Arpitan: Val d'Aoûta [val duta] ; Walser: Augschtalann or Ougstalland; Piedmontese: Val d'Osta), officially the Autonomous Region of Aosta Valley, is a mountainous autonomous region in northwestern Italy. It is bordered by Auvergne-Rhône-Alpes, France, to the west; by Valais, Switzerland, to the north; and by Piedmont, Italy, to the south and east. The regional capital is Aosta.

Covering an area of 3,263 km (1,260 sq mi) and with 122,714 inhabitants as of 2025, it is the smallest, least populous, and least densely populated region of Italy. The province of Aosta having been dissolved in 1945, the Aosta Valley region was the first region of Italy to abolish provincial subdivisions, followed by Friuli-Venezia Giulia in 2017 (where they were reestablished later). Provincial administrative functions are provided by the regional government. The region is divided into 74 comuni (French: communes).

Chlodio (also Clodio, Clodius, Clodion, Cloio or Chlogio, probably died after 450), was a Frankish king who attacked and then apparently ruled Roman-inhabited lands around Cambrai and Tournai, near the modern border of Belgium and France. Very little is known about him, and he is mentioned only briefly in a small number of much later records.

His conquests gave him influence probably reached as far south as the River Somme. It represented an important change, extending Frankish rule more deeply within the Roman Empire, quite distant from the border regions near the Rhine where the Franks had already been established for a long time. Gregory of Tours reported that in his time people believed that the Merovingian dynasty, who were still ruling in his time, were descended somehow from Chlodio.

Spain, officially the Kingdom of Spain, is a country in Southern and Western Europe with territories in North Africa. Featuring the southernmost point of continental Europe, it is the largest country in Southern Europe and the fourth-most populous European Union (EU) member state. Spanning the majority of the Iberian Peninsula, its territory also includes the Canary Islands, in the Eastern Atlantic Ocean; the Balearic Islands, in the Western Mediterranean Sea; and the autonomous cities of Ceuta and Melilla, in mainland Africa. Peninsular Spain is bordered to the north by France, Andorra, and the Bay of Biscay; to the east and south by the Mediterranean Sea and Gibraltar; and to the west by Portugal and the Atlantic Ocean. Spain's capital and largest city is Madrid; other major urban areas include Barcelona, Valencia, Seville, Zaragoza, Málaga, Murcia, and Palma de Mallorca.

In early antiquity, the Iberian Peninsula was inhabited by Celts, Iberians, and other pre-Roman peoples. The Roman conquest of the Iberian peninsula created the province of Hispania, which became deeply Romanised and later Christianised. After the fall of the Western Roman Empire, the peninsula was conquered by tribes from Central Europe, among them the Visigoths, who established the Visigothic Kingdom centred on Toledo. In the early 8th century, most of the peninsula was conquered by the Umayyad Caliphate, with Al-Andalus centred on Córdoba. The northern Christian kingdoms of Iberia launched the so-called Reconquista, gradually repelling and ultimately expelling Islamic rule from the peninsula, culminating with the fall of the Nasrid Kingdom of Granada. The dynastic union of the Crown of Castile and the Crown of Aragon in 1479 under the Catholic Monarchs is often seen as the de facto unification of Spain as a nation state.

In the early modern period, from the Renaissance (c. 1500–1550) to the Revolution (1789–1804), the Kingdom of France was a monarchy ruled by the House of Bourbon (a Capetian cadet branch). This corresponds to the so-called Ancien Régime ("old rule"). The territory of France during this period increased until it included essentially the extent of the modern country, and it also included the territories of the first French colonial empire overseas.

The period is dominated by the figure of the "Sun King", Louis XIV (his reign of 1643–1715 being one of the longest in history), who managed to eliminate the remnants of medieval feudalism and established a centralized state under an absolute monarch, a system that would endure until the French Revolution and beyond.

The Kingdom of Navarre (/nəˈvɑːr/ nə-VAR), originally the Kingdom of Pamplona, occupied lands on both sides of the western Pyrenees, with its northernmost areas originally reaching the Atlantic Ocean (Bay of Biscay), between present-day Spain and France.

The medieval state took form around the city of Pamplona during the first centuries of the Iberian Reconquista. The kingdom had its origins in the conflict in the buffer region between the Carolingian Empire and the Ummayad Emirate of Córdoba that controlled most of the Iberian Peninsula. The city of Pamplona (Latin: Pompaelo; Basque: Iruña), had been the main city of the indigenous Vasconic population and was located in a predominantly Basque-speaking area.

International Gothic is a period of Gothic art that began in Burgundy, France, and northern Italy in the late 14th and early 15th century. It then spread very widely across Western Europe, hence the name for the period, which was introduced by the French art historian Louis Courajod at the end of the 19th century.

The spread of ideas and portable works, such as illuminated manuscripts throughout Europe led to consensus among artists and their patrons that considerably reduced variation in national styles. The main influences were northern France, the Duchy of Burgundy, Flanders and Brabant, the Imperial court in Prague, and Italy. Royal marriages such as that between Richard II of England and Anne of Bohemia helped to spread the style.

A seminary, school of theology, theological college, or divinity school is an educational institution for educating students (sometimes called seminarians) in scripture and theology, generally to prepare them for ordination to serve as clergy, in academics, or mostly in Christian ministry.

The English word is taken from Latin: seminarium, translated as 'seed-bed', an image taken from the Council of Trent document Cum adolescentium aetas, 'Since the age of adolescence' which called for the first modern seminaries.

The Huygens–Fresnel principle (named after Dutch physicist Christiaan Huygens and French physicist Augustin-Jean Fresnel) states that every point on a wavefront is itself the source of spherical wavelets and that the secondary wavelets emanating from different points mutually interfere. The sum of these spherical wavelets forms a new wavefront. As such, the Huygens–Fresnel principle is a method of analysis applied to problems of luminous wave propagation both in the far-field limit and in near-field diffraction as well as reflection.

France was ruled by monarchs from the establishment of the kingdom of West Francia in 843 until the end of the Second French Empire in 1870, with several interruptions.

Classical French historiography usually regards Clovis I, king of the Franks (r. 507–511), as the first king of France. However, most historians today consider that such a kingdom did not begin until the establishment of West Francia, after the fragmentation of the Carolingian Empire in the 9th century.
