allies. He achieved both goals through a web of al-
liances collectively known as the Bismarckian system,
with which he dominated European diplomacy for
twenty years (1871–90). Bismarck’s accomplishment
radically altered European statecraft. Whereas the Met-
ternichian system had kept the peace by a delicate bal-
ance of power in which none of the great powers
became too dominant and none felt too threatened, the
Bismarckian system kept peace through the lopsided
superiority of the German alliances and the compara-
tive weakness of France.
French nationalists nonetheless dreamt of the day
of revenge—la revanche—on Germany, the day when
the republic would reclaim “the lost provinces” of Al-
sace and Lorraine, whose borders were marked on the
maps of French schools in a deep black. Realistic na-
tionalists such as the hero of 1870, Léon Gambetta, un-
derstood that Germany had become too powerful to
fight alone. The French must wait for revanche;in Gam-
betta’s words, they should “[t]hink of it always, speak of
it never.” Despite a war scare in 1875 and a tense period
during the Boulangist nationalism of the late 1880s, no
French government planned a war of revenge.
The first treaty in Bismarck’s alliance system was
the Three Emperors’ League (Dreikaiserbund) of 1873, an
outgrowth of state visits exchanged by William I of
Germany, Franz Joseph of Austria-Hungary, and
Alexander II of Russia. The Dreikaiserbundrepresented an
amicable understanding (an entente) among recent ri-
vals who shared a belief in monarchical solidarity.
(France remained the only republic in monarchical Eu-
rope.) The king of Italy soon embraced this counterrev-
olutionary league, siding with Germany despite the
debt Italians owed to the French from their wars of uni-
fication. The British remained outside this league, fa-
voring a policy of continental nonalignment that came
to be called splendid isolation.
The development of the Bismarckian system accel-
erated as a result of warfare in the Balkans in 1875–78,
which convinced Bismarck to seek more formal treaties.
The provinces of Bosnia and Herzegovina (see map
27.1) rebelled against Turkish rule in 1875, and the
Principality of Serbia intervened to support them.
The Serbs had won autonomous government in their
rebellion of 1817 and had become the center of Pan-
Slavism, an ardent nationalism dedicated to the unity of
the southern Slavs. The insurrection against the Ot-
toman Empire next spread to Bulgaria in 1876, and the
Turks responded with violent repression known in the
European press as “the Bulgarian horrors.” This enlarged
Balkan war forced the European powers to address a
problem that had come to be called the eastern ques-
tion. This was the question of the survival of the
Ottoman Empire—still known as “the sick man of Eu-
rope”—and the fate of territories under the control of
Constantinople. The eastern question posed the danger
of Austro-Russian conflict because both governments
coveted Ottoman territory in the Balkans. To avoid
such a confrontation, Bismarck adopted the role of “the
honest broker” of the eastern question and presided
over the Congress of Berlin (1878) to end the fighting.
The British endorsed the congress because it served
their policy of preserving the Ottoman Empire rather
than dismantling it. The Berlin settlement placated
Turkish honor by returning some territory lost in the
fighting, and it awarded Balkan territory to both the
Russians (Bessarabia) and the Austrians (Bosnia-
Herzegovina). Bismarck bought French backing with
support for colonial expansion. The Slavic nationalist
movements of the Balkans—both Serbian and Bulgar-
ian—were not satisfied: Serbs won their independence
