stand down. When the Russians did not, the German
army invaded Belgium. This violation of the interna-
tional treaty on Belgian neutrality (“a scrap of paper” in
the phrase of the chancellor Bethmann-Hollweg of
Germany) led the British to recognize that their inter-
ests were on the side of the French. For centuries,
British policy had opposed the dominance of the low-
lands (from where an invasion might be launched) by
any strong power—by Spain, later by France, or now
by Germany. European declarations of war rained down
in the first days of August, until the members of the
Triple Alliance, (except Italy) and the Triple Entente
were at war with each other over a crisis of Balkan na-
tionalism. As the British foreign secretary observed, af-
ter a long cabinet meeting had chosen war and the
streetlights of London were being extinguished for day-
break, “The lights are going out all over Europe.” That
somber statement was a good metaphor for the four
years of darkness that followed; at the time, however,
public opinion greeted the war with great enthusiasm
(see illustration 27.3) and brisk sales were made of
French (or German) dictionaries for “the stroll to Paris”
(or Berlin). Only limited expressions of antiwar senti-
ment were heard after Jean Jaurès, the leading socialist
proponent of organizing workers against war, was assas-
sinated on July 31 (three days after the assassination of
Franz-Ferdinand and the day before mobilization of the
French and German armies).
Other belligerents entered the war slowly. The Ot-
toman Empire, whose continuing collapse in the
Balkans had been such a factor in the coming of the
war, followed its close ties with Germany and its his-
toric rivalry with Russia into the war in October 1914.
Italy remained neutral, declaring that the Triple Al-
liance was binding only if Germany or Austria were in-
vaded, not when they invaded small neighbors. The
Italians then negotiated with both sides and eventually
joined the entente powers in 1915, when a secret
Treaty of London promised them significant territorial
compensation at the expense of the Habsburg Empire.
The United States likewise remained neutral despite
significant pro-British sentiment. Although a dispute
over submarine warfare clouded German-American re-
lations, President Woodrow Wilson kept the country
out of war and contributed to efforts for a negotiated
peace until entering the war on the side of the entente
powers in 1917.
World War I: From the Invasion
of Belgium to a World War
The decisive theatre of the war was the western front in
France and Belgium, although the largest armies met on
the eastern front and fighting reached into the Middle
East, Africa, and the Pacific Islands. More than sixty
million men were mobilized to fight, including millions
of Africans, Indians, Canadians, Australians, and Ameri-
cans. The French, for example, conscripted 519,000
Africans to fight in Europe. By 1917 the belligerents in-
cluded Japan and China (both on the side of the west-

War Enthusiasm.The beginning of
World War I was greeted with remark-
able public enthusiasm. Cheering
crowds volunteered to fight and hailed
departing soldiers. One of the most
memorable photographs of this war
fever was taken in Munich on the day
that war was declared, August 2, 1914.
Holding his hat near the center of the
happy crowd is Adolf Hitler, who soon
joined a Bavarian regiment and fought in
the war. The photographer, Heinrich
Hoffmann, later became Hitler’s court
photographer.
