THE LEGACY OF WORLD WAR I 15

THE BREAKUP OF THE
AUSTRO-HUNGARIAN EMPIRE 1918–
The Hapsburg Empire’s collapse led to three new
states: Austria, Hungary, and Czechoslovakia.
Former Austrian territory was added to Poland,
Romania, and what later became Yugoslavia. Austria
had to pay reparations, was forbidden to unite with
Germany, and saw its army restricted. The old
Kingdom of Hungary lost two-thirds of its land and
many ethnic Hungarians to Romania and elsewhere.
Signing the Treaty of Versailles
WRITING THE PEACE
The victorious Allied politicians and
diplomats met in Paris in 1919 to draw up a
series of treaties with the defeated Central
Powers, each one named after the palaces,
chateaux, and towns to the west of Paris
where they were signed. The main treaty
was signed with Germany at Versailles
in June 1919, followed by St.-Germain-
en-Laye with Austria in September
1919, Neuilly-sur-Seine with Bulgaria in
November 1919, Trianon with Hungary
in June 1920, and finally the abortive
Sèvres treaty with Turkey in August 1920.

1915–1922 Around
1.5 million Turkish
Armenians are killed by
Turkish Nationalists.
1918 Russia signs the
Treaty of Brest-Litovsk,
giving up its claims
on lands west of the
Brest-Litovsk line.
THE LEGACY
OF WORLD WAR I
The end of war in Europe in 1918 saw the collapse of four
major empires. The map of the continent needed to be redrawn,
and the future home of millions of people decided. As new states
emerged and old conflicts were slowly resolved, the legacy of the
war continued to be felt across Europe for many years.
The peace treaties that settled the
future of Europe after 1919 were the
result of numerous compromises
between the “Big Four”: the victorious
Allied powers of the US, UK, France,
and Italy. American president Woodrow
Wilson wanted to forge a liberal peace
settlement based on national self-
determination, while French prime
minister Georges Clemenceau wanted
above all to ensure the future security
of his country and make Germany pay
for the war—a view that was shared by
David Lloyd George, prime minister
of Britain. The resulting treaties had
the overall effect of pleasing no one,
and left the people and governments of
many countries profoundly dissatisfied
with the outcome.
“My home policy: I wage war. My foreign policy: I wage
war. All the time I wage war.”
GEORGES CLEMENCEAU, 1918
Territorial disputes continued to divide
nations, notably in Eastern Europe,
while actual fighting continued in
Turkey until 1922. Many of the new
states were crudely carved out of
Austro-Hungary and the other old
empires, while defeated Germany
emerged as a shrunken republic and
imperial Russia, excluded from the
peace talks, became the world’s first
Communist state.
While some problems were
addressed by the peace treaties,
the legacy of the war had profound
social, economic, and political
consequences across Europe and
Asia, and would become one of
the defining causes of a new world
war within 20 years.

AFTER THE WAR
The borders of many European countries were
redrawn after World War I, as empires collapsed and
new countries were born. This new settlement was
often violent, and left its own damaging legacy.

END OF THE RUSSIAN EMPIRE 1917–
The February Revolution of 1917 that overthrew
the Romanov Czar and the October Revolution
that ended the provisional government led to
a Communist takeover of Russia. The Bolshevik
regime arranged a cease-fire with Germany in
December 1917, and in March 1918 signed the
Treaty of Brest-Litovsk, renouncing its claims on
Finland, the Baltic provinces, Poland, and Ukraine.

EMERGING STATES 1918–
The collapse of the Ottoman, German, Russian,
and Austro-Hungarian empires at the end of the
war led to the formation of new states in central
Europe: Estonia; Finland; Austria; Czechoslovakia;
Poland; Hungary; Lithuania; Latvia; and the
Kingdom of Serbs, Croats, and Slovenes. They
were joined by the Irish Free State, which broke
free from Britain in 1922 after a brutal civil war.
