The Western Front was characterized by extensive trench warfare, with both sides constructing elaborate systems of trenches and fortifications to defend their positions. The fighting was highly intense and often resulted in heavy casualties, particularly during large-scale offensives such as the Battle of the Somme and the Battle of Verdun.
The Western Front was also notable for the use of new military technologies and tactics, such as tanks, aircraft, and chemical weapons, which had significant impacts on the conduct of warfare.
The Western Front remained the dominant and decisive theater of operations throughout World War I until the final Allied offensive, known as the Meuse-Argonne Offensive, which led to the armistice and the eventual defeat of Germany in November 1918.
