Germany was a participant of the First World War, in the guise of the then-German Empire, or Deutsches Reich. The German Empire is with Austro-Hungarian Empire, Kingdom of Bulgaria and Ottoman Empire, one of the principal participant of the First World War on the side of the Central Powers.
The Germans, as the Austrian and Hungarian population, was mostly favorable to an open conflict against the Entente forces for few reasons. German Empire wanted to do a preventive war against French Republic and British Empire to protect their economic, politic and territorial supremacy in Europe. But they also wanted to help their Austro-Hungarian allies in war with Russian Empire for the control of the Balkans. The Kaiser Wilhelm II, with his major-state chief Helmuth Von Moltke and a strategy team, elaborated the Schlieffen Plan.
The hostilities on the Western front, which the game depicts, started due to the German invasion of Belgium and France in August 1914, which continued until it was stopped at the First Battle of the Marne later that year.
The following stalemate and trench warfare, continued into the years of 1915 and 1916 when Germans forces tried to take the stronghold city of Verdun, where the French army pushed them back, they also had to protect all the sectors they gained early in the conflict at the Battle of the Somme when they had to fight against the first tank used in all the military history.
In 1918, German Empire made one last bloody breakthrough attempt at the Kaiserschlacht (Battle of the kaiser) but the French and British army could stop it while wiping out fat loss. The year end as the war with an astute counterattack where, in the Hundred Days' Offensive, a combined Anglo-Franco-American force almost drove the German armies back to the Franco-German frontiers before the armistice on the 11th of November.
