the chief feature of the war on the western front was
Western Front (World War I) The Western Front was the main theatre of war during the First World War. Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France. The tide of the advance was dramatically turned with the Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trenches, stretching from the North Sea to the Swiss frontier with France, which changed little except during early 1917 and in 1918.
Hundred Years' War The war owes its historical significance to multiple factors. By its end, feudal armies had been largely replaced by professional troops, and aristocratic dominance had yielded to a democratisation of the manpower and weapons of armies. Although primarily a dynastic conflict, the war gave impetus to ideas of French and English nationalism. The wider introduction of weapons and tactics supplanted the feudal armies where heavy cavalry had dominated, and artillery became important. The war precipitated the creation of the first standing armies in Western Europe since the time of the Western Roman Empire and thus helping to change their role in warfare. With respect to the belligerents, in France, civil wars, deadly epidemics, famines, and bandit free-companies of mercenaries reduced the population drastically. English political forces over time came to oppose the costly venture. The dissatisfaction of English nobles, resulting from the loss of their continental landholdings, became a factor leading to the civil wars known as the Wars of the Roses (1455â€“1487).
