Question: What major conflict occurred during the Crisis of the Late Middle Ages, on the continent containing the region which shares a border with Champagne-Ardenne?

full_context: Document 1: Devil's Backbone State Forest: Although much of future state forest was too steep and the soil too thin for agriculture, it nonetheless was part of a growing Virginia economy. The first industry to use the forest was iron furnaces established in the mid-18th century and existing until after the Civil War. Isaac Zane, a Quaker from Pennsylvania, built the first two of these furnaces (Zane's Old Furnace 1768-74 and The Marlboro Works 1772-95) and received grants of forest land which included the future state forest to be used to make charcoal as fuel.
Document 2: Rhine: Until the early 1980s, industry was a major source of water pollution. Although many plants and factories can be found along the Rhine up into Switzerland, it is along the Lower Rhine that the bulk of them are concentrated, as the river passes the major cities of Cologne, Düsseldorf and Duisburg. Duisburg is the home of Europe's largest inland port and functions as a hub to the sea ports of Rotterdam, Antwerp and Amsterdam. The Ruhr, which joins the Rhine in Duisburg, is nowadays a clean river, thanks to a combination of stricter environmental controls, a transition from heavy industry to light industry and cleanup measures, such as the reforestation of Slag and brownfields. The Ruhr currently provides the region with drinking water. It contributes 70 m3/s (2,500 cu ft/s) to the Rhine. Other rivers in the Ruhr Area, above all, the Emscher, still carry a considerable degree of pollution.
Document 3: Late Middle Ages: Around 1300–1350 the Medieval Warm Period gave way to the Little Ice Age. The colder climate resulted in agricultural crises, the first of which is known as the Great Famine of 1315-1317. The demographic consequences of this famine, however, were not as severe as the plagues that occurred later in the century, particularly the Black Death. Estimates of the death rate caused by this epidemic range from one third to as much as sixty percent. By around 1420, the accumulated effect of recurring plagues and famines had reduced the population of Europe to perhaps no more than a third of what it was a century earlier. The effects of natural disasters were exacerbated by armed conflicts; this was particularly the case in France during the Hundred Years' War.
Document 4: Southern California: The Tech Coast is a moniker that has gained use as a descriptor for the region's diversified technology and industrial base as well as its multitude of prestigious and world-renowned research universities and other public and private institutions. Amongst these include 5 University of California campuses (Irvine, Los Angeles, Riverside, Santa Barbara, and San Diego); 12 California State University campuses (Bakersfield, Channel Islands, Dominguez Hills, Fullerton, Los Angeles, Long Beach, Northridge, Pomona, San Bernardino, San Diego, San Marcos, and San Luis Obispo); and private institutions such as the California Institute of Technology, Chapman University, the Claremont Colleges (Claremont McKenna College, Harvey Mudd College, Pitzer College, Pomona College, and Scripps College), Loma Linda University, Loyola Marymount University, Occidental College, Pepperdine University, University of Redlands, University of San Diego, and the University of Southern California.
Document 5: Belgium: Belgium, officially the Kingdom of Belgium, is a country in Western Europe bordered by France, the Netherlands, Germany and Luxembourg. A small and densely populated country, it covers an area of 30,528 square kilometres (11,787 sq mi) and has a population of more than 11 million. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch - speaking, mostly Flemish community, which constitutes about 59 percent of the population, and the French - speaking, mostly Walloon population, which comprises about 40 percent of all Belgians. Additionally, there is a small group of German speakers, numbering around one percent, who live in the East Cantons. The capital and largest city is Brussels; other major cities are Antwerp, Ghent, Charleroi and Liège.
Document 6: Institute of technology: Hogeschool is used in Belgium and in the Netherlands. The hogeschool has many similarities to the Fachhochschule in the German language areas and to the ammattikorkeakoulu in Finland.
Document 7: Southern Europe: The Late Middle Ages represented a period of upheaval in Europe. The epidemic known as the Black Death and an associated famine caused demographic catastrophe in Europe as the population plummeted. Dynastic struggles and wars of conquest kept many of the states of Europe at war for much of the period. In the Balkans, the Ottoman Empire, a Turkish state originating in Anatolia, encroached steadily on former Byzantine lands, culminating in the Fall of Constantinople in 1453.
Document 8: Middle Ages: The first years of the 14th century were marked by famines, culminating in the Great Famine of 1315–17. The causes of the Great Famine included the slow transition from the Medieval Warm Period to the Little Ice Age, which left the population vulnerable when bad weather caused crop failures. The years 1313–14 and 1317–21 were excessively rainy throughout Europe, resulting in widespread crop failures. The climate change—which resulted in a declining average annual temperature for Europe during the 14th century—was accompanied by an economic downturn.
Document 9: Belgium: Belgium was the first continental European country to undergo the Industrial Revolution, in the early 19th century. Liège and Charleroi rapidly developed mining and steelmaking, which flourished until the mid-20th century in the Sambre and Meuse valley and made Belgium among one of the three most industrialized nations in the world from 1830 to 1910. However, by the 1840s the textile industry of Flanders was in severe crisis, and the region experienced famine from 1846 to 1850.After World War II, Ghent and Antwerp experienced a rapid expansion of the chemical and petroleum industries. The 1973 and 1979 oil crises sent the economy into a recession; it was particularly prolonged in Wallonia, where the steel industry had become less competitive and experienced serious decline. In the 1980s and 1990s, the economic center of the country continued to shift northwards and is now concentrated in the populous Flemish Diamond area.By the end of the 1980s, Belgian macroeconomic policies had resulted in a cumulative government debt of about 120% of GDP. As of 2006, the budget was balanced and public debt was equal to 90.30% of GDP. In 2005 and 2006, real GDP growth rates of 1.5% and 3.0%, respectively, were slightly above the average for the Euro area. Unemployment rates of 8.4% in 2005 and 8.2% in 2006 were close to the area average. By October 2010, this had grown to 8.5% compared to an average rate of 9.6% for the European Union as a whole (EU 27). From 1832 until 2002, Belgium's currency was the Belgian franc. Belgium switched to the euro in 2002, with the first sets of euro coins being minted in 1999. The standard Belgian euro coins designated for circulation show the portrait of the monarch (first King Albert II, since 2013 King Philippe).
Document 10: Science and technology in Wallonia: Science and technology in Wallonia, the southern region of Belgium (Europe), is well developed with the presence of several universities and research institutes.
Document 11: Jacques-Cartier River: Logging in the Laurentian highlands became an important economic activity during the second half of the 18th century. The Jacques-Cartier River was used for log drives to transport the logs to the Saint-Lawrence River and to the mills downstream. This practice was only stopped in 1975. With the settlement of French immigrants near the river's mouth came the formation of townships (modelled after English townships after their conquest of 1759) and new industries appeared such as flour mills.
Document 12: Late Middle Ages: Around 1300, centuries of prosperity and growth in Europe came to a halt. A series of famines and plagues, including the Great Famine of 1315–1317 and the Black Death, reduced the population to around half of what it was before the calamities. Along with depopulation came social unrest and endemic warfare. France and England experienced serious peasant uprisings, such as the Jacquerie and the Peasants' Revolt, as well as over a century of intermittent conflict in the Hundred Years' War. To add to the many problems of the period, the unity of the Catholic Church was shattered by the Western Schism. Collectively these events are sometimes called the Crisis of the Late Middle Ages.
Document 13: Ardennes: The trees and rivers of the Ardennes provided the charcoal industry assets that enabled the great industrial period of Wallonia in the 18th and 19th centuries, when it was arguably the second great industrial region of the world, after England. The greater region maintained an industrial eminence into the 20th century, after coal replaced charcoal in metallurgy.
Document 14: England in the Middle Ages: The 14th century in England saw the Great Famine and the Black Death, catastrophic events that killed around half of England's population, throwing the economy into chaos and undermining the old political order. Social unrest followed, resulting in the Peasants' Revolt of 1381, while the changes in the economy resulted in the emergence of a new class of gentry, and the nobility began to exercise power through a system termed bastard feudalism. Nearly 1,500 villages were deserted by their inhabitants and many men and women sought new opportunities in the towns and cities. New technologies were introduced, and England produced some of the great medieval philosophers and natural scientists. English kings in the 14th and 15th centuries laid claim to the French throne, resulting in the Hundred Years' War. At times England enjoyed huge military success, with the economy buoyed by profits from the international wool and cloth trade, but by 1450 the country was in crisis, facing military failure in France and an ongoing recession. More social unrest broke out, followed by the Wars of the Roses, fought between rival factions of the English nobility. Henry VII's victory in 1485 conventionally marks the end of the Middle Ages in England and the start of the Early Modern period.
Document 15: Institute of technology: In addition, France's education system includes many institutes of technology, embedded within most French universities. They are referred-to as institut universitaire de technologie (IUT). Instituts universitaires de technologie provide undergraduate technology curricula. 'Polytech institutes', embedded as a part of eleven French universities provide both undergraduate and graduate engineering curricula.
