- Introduction
In the first half of the twentieth century, global wars and a
severe depression resulted in the decline of Western Europe.
The second period was defined by the great rivalry between
the Soviet Union and the United States. This period, known
as the cold war, led to the creation of alliance systems and
economic unions. Each crisis extended the nature of conflict
more fully around the globe.
Confidence and Internationalism on the War's Eve
International organization was one of the harbingers of
progress. The Geneva Convention of 1864, the establishment
of the Red Cross, the Telegraphic and Postal unions all
pointed toward greater international cooperation. Scientists
and industrialists began to display their accomplishments at
great fairs and international gatherings.
Internationalization had two weaknesses: dependence on
Western dominance and the emergence of strong nationalist
movements. These weaknesses affected political cooperation,
in particular. Discussions at the Hague in 1899 did result
in international agreements on treatment of war prisoners and
banned certain types of warfare, but disarmament was not
accepted. A permanent court of arbitration, the World Court,
did survive the conference.
- World War I
- Introduction
To many contemporary observers, the end of the nineteenth
century embodied the concept of human progress. Few believed
that international catastrophe was near at hand.
- The Onset of World War I
To distract citizens from internal problems, European nations
used first imperial conquests and then, after 1900, military
growth. The two alliance systems that enmeshed the major
European nations focused increasingly on the Balkans, where
Russia and Austria-Hungary were engaged in an uneasy struggle
for dominance. In the Balkans, a variety of small, recently
independent nations and Slavic minorities sought advantages
by appealing to whichever of the European powers seemed
likely to advance their causes.
When the Austrian Archduke Ferdinand was assassinated in
1914, Austria declared war on Serbia. Russia immediately
mobilized its forces to protect its Balkan ally. Germany,
France, and Britain were rapidly drawn into the conflict by
terms of the various alliance systems.
- Patterns of War in Europe
There were three fronts to the war. The first, the western
front, was in France, where German armies confronted French
and British troops for much of the war. The second front
covered a great distance across Poland and Russia. This
eastern front was the battleground between German and Russian
forces. The Italian front developed after 1915 between
Austria-Hungary and Italy. Surface sea battles were uncommon
during World War I, but the Germans mounted an intensive
submarine campaign against Allied shipping. The western front
featured trench warfare, where the new technology of machine
guns, barbed wire, poison gas, and massed artillery wreaked
havoc on the contending armies. There was little mobility
along the western front. The eastern front was more mobile.
The lines moved into western Russia. To meet the demands of
total war, governments more closely controlled national
economies and rationed scarce resources. Censorship and
propaganda were common. Sacrifices by combatants and
civilians were enormous.
- The War Outside Europe
Although the war was fought mostly in Europe between European
nations, others were drawn into the conflict. The British
called on contingents of troops from their Dominions in
Australia, Canada, and New Zealand. The United States was
slowly involved in the war. Initially the United States
profited from its neutral status, exporting materials and
food to the Allies. German submarine warfare eventually
affected American ships. In 1917, the United States entered
the war on the side of the Allies and helped to turn the tide
of battle against Germany.
- Combatants in Africa, Asia and the Middle East
There were minor skirmishes in the German colonies of Africa,
and the French used African troops in Europe. Indian
contingents served in the British army. Nationalism spread
from Europe to the colonies as a result of their
participation in World War I. Japan entered the war on the
side of the Allies as a justification for seizing German
colonies in the Pacific. China also declared war on Germany
in 1917, but never actually participated as a combatant.
In the Middle East, the Ottoman Empire's decision to join the
German alliance spelled the end of the Turks' hold over Arab
regions. The British fomented rebellions among Arabs seeking
independence from the Ottomans. The British also promised a
Middle Eastern homeland to the Jews in the Balfour
Declaration of 1917. Overall, the war advanced the prestige
and power of the United States and Japan, but diminished
Europe's hold over global empires.
- The War's End
Before the fighting ceased, the Russian Revolution of 1917
took Russia out of World War I. Lenin and the communists
signed the Treaty of Brest-Litovsk with the Germans. German
fortunes on the western front were not so good. By 1918, the
French, British and American troops pushed the German troops
back to the French borders. The military installed a
civilian government to take blame for the defeat. The new
government sued for peace in 1918.
- The Peace and the Aftermath
The peace agreed to at Versailles proved satisfactory to no
one. France obtained provinces lost in the war, but no
security against future German aggression. Japan's claims
for compensation were virtually ignored. The American
concept of an international body to prevent war was enacted
in the League of Nations, but the U.S. Congress refused to
join and entered a period of diplomatic isolation. China
lost territories to Japan. New nations were carved out of
central Europe, but they were small and weak. Germany was
forced to pay reparations for the war, which produced
internal discontent with the civilian government and economic
disaster. Russia, now communist, was not included in the
conference. The various discontents led to universal
diplomatic insecurity.
- The War's Devastations and Dislocations
The war was devastating both in terms of manpower and the
European psyche. The loss of men reduced available labor
forces and produced economic instability. Financial
insecurity resulted from the massive amounts of credit
extended to combatants during the war. Increased government
spending led to inflation. In terms of European imperialism,
there was little overt change, but colonies anticipated
enactment of President Wilson's announced programs of self-
determination.
The Ottoman Empire ceased to exist. It was replaced by a
stronger Turkish republic and a group of mandates that
divided up the Arab regions between France and Britain. A
few monarchies under Arab or Persian rulers also emerged from
the wreckage of the Ottoman Empire. The world trade system
had been reorganized with Japan and the United States as
major forces. The League of Nations, on which so many hopes
had been based, proved to be little more than an ineffective
discussion group.
- The Great Depression
- Introduction
The depression that dominated the 1930s affected the entire
world trade system. The Great Depression led to the
development of new governmental policies and triggered
political extremism.
- Causes of Economic Instability
There were numerous economic problems in the aftermath of
World War I. Germany suffered from massive inflation, which
was difficult to control. Britain, dependent on exports,
found a global market with much stiffer competition.
Agricultural overproduction sent prices for food products
plummeting in all nations. In Europe, falling farm prices
made it more difficult to repay war loans. Overproduction
was a particular problem in dependent countries of the world
trade system. The inability of colonies and dependent
regions to purchase European manufactured goods weakened
demand for Western goods. Nationalism frustrated
international attempts to deal with these problems. Tariffs
barriers, which further reduced trade, were erected in many
nations.
- Collapse and Crisis
The economic collapse first occurred in the United States in
1929. As American banks closed their doors, Europe, which
remained dependent on American credit, was drawn into the
crisis. Investment funds were withdrawn when creditors went
bankrupt. Without capitalization, industrial production fell
and with it the demand for labor. Massive unemployment made
it impossible for large numbers of people to consume goods,
thus contributing to falling demand. The social devastation
of the depression was evident at all levels. Symptoms of the
declining economy lasted until 1939.
- Worldwide Impact
One of the few economies that resisted the general trend to
depression belonged to the Soviet Union. Without ties to
most of the West, the Soviets were unaffected by the drop in
worldwide demand. Colonial nations that depended on exports
of raw materials suffered enormously. Japan, industrialized,
but heavily dependent on exports, suffered typically high
unemployment figures.
The depression increased Japanese paranoia about the West and
promoted more aggressive imperialism in Asia. In the West,
itself, the depression prompted new, government-led welfare
schemes and political radicalism. In part, reactions to the
depression helped to create the conditions that led to World
War II.
- World War II
- Introduction
Military expansion in Germany and Japan led to a series of
diplomatic crises during the 1930s. Passive responses from
other nations encouraged more aggressive behavior.
- New Authoritarian Regimes
The depression fragmented Japanese politics and gave rise to
various radical, ultranationalist groups. One military
faction attempted a coup in 1932. The coup failed, but
resulted in the establishment of a moderate military
government for four years. Militarism produced a more
aggressive foreign policy toward China, still attempting to
recover from the 1911 revolution. The Japanese army entered
the Chinese province of Manchuria in 1931. When the League
of Nations condemned the aggression, the Japanese withdrew
from the organization.
The depression also triggered political radicalism in
Germany. In the 1920s, the National Socialist party under
Adolf Hitler began to gain popularity as an advocate of
stronger central government and aggressive foreign policy.
Hitler was able to take power in 1933 legally, but soon
abolished parliamentary government and established a
totalitarian regime. Hitler removed all political rivals,
launched a racist attack on Jews, and built up the German war
machine. In Italy, Benito Mussolini had developed a similar
fascist government in the 1920s. Hitler's success in Germany
galvanized the Italian government.
- The Steps Toward War
Hitler withdrew Germany from the League of Nations and
intentionally broke the terms of the Treaty of Versailles by
suspending reparations, rearming, and entering the Rhineland.
Italy attacked Ethiopia in 1935 with impunity. When civil
war broke out in Spain, Italy and Germany actively supported
the right-wing faction. Only when Germany declared a union
with Austria and invaded Czechoslovakia in 1938 did the other
European nations demand a conference. At the Munich
conference, the leaders of France and Britain acceded to
Hitler's demands in return for the hope of continued peace.
The policy of appeasement failed, when Hitler's forces
swallowed all of Czechoslovakia in 1939. The Soviet Union
and Germany signed a peace treaty in the same year. Finally,
when Hitler invaded Poland in 1939, Britain and France
declared war.
In Asia, Japan's aggression against China spread to the
region around Beijing in 1937. The Japanese military rapidly
extended their control over much of eastern China, but were
unable to suppress resistance entirely. A stalemate set in
that lasted until 1945. In 1940, Germany, Italy, and Japan
signed a formal alliance, the Tripartite Pact. France and
Britain were ill-prepared to face renewed conflict after the
devastation of World War I. The United States continued to
follow a diplomatic course of isolation.
- The Course of the War: Japan's Advance and Retreat
The first years of the war featured widespread Japanese
successes in the Asian theater of war. With no farther
advance likely in China, Japan turned to other areas of Asia.
French Indochina, British Malaysia, and Burma were all
assaulted. The United States, with possessions in the
Philippines and Hawaii, attempted to halt the Japanese
advance diplomatically. During negotiations, the Japanese
attacked the American naval base at Pearl Harbor in the
Hawaiian islands in 1941. Following the loss of the
Philippines, the American forces recovered in the Pacific.
Moving from island to island, the American navy and marines
approached the Japanese home islands by 1944.
- Germany Overreaches
In the first stages of the war, German armored columns
practicing Blitzkrieg rolled through the poorly defended
nations of Poland, Denmark, Norway, Holland, Belgium, and
France. By 1940, much of continental Europe was under German
rule. A collaborationist French regime ruled southern France
from Vichy. Britain, led by Winston Churchill, remained as
the last Allied bastion in Europe.
With Europe under control, Hitler proceeded to carry out his
final solution, the genocidal extermination of the Jewish
population. Six million died in concentration camps. With
western Europe prostrate, Hitler ordered the invasion of the
Soviet Union in 1940. Despite massive casualties, the
Russian forces held back the German armies. The protracted
invasion of the Soviet Union critically weakened German
forces just as the United States entered the war in 1941.
U.S. and British forces launched an offensive against Germany
in northern Africa at the same time as the Soviet Union
turned back the last major German offensive. The Soviet
Union then began an offensive that reached Berlin in 1945.
Between 1942 and 1945, the U.S. and Britain invaded Italy,
then France, and finally Germany. As the Allies prepared
their final assault, Hitler committed suicide rather than
face defeat. The war in the Pacific ended shortly
afterwards. The American use of atomic bombs to reduce the
cities of Nagasaki and Hiroshima induced the Japanese to give
up the war effort.
- Human Costs
The war was destructive of both combat troops and civilian
populations. The Japanese committed atrocities against the
Chinese population, and Hitler's genocidal assault on the
Jews during the Holocaust killed millions. Both German and
Allied air forces targeted civilian populations as targets in
bombing raids. The most extreme example of civilian bombing
was the use of atomic bombs against Japan at the end of the
war. At least 35 million people died during World War II.
- The Settlement of World War II
In the peace settlement that followed World War II, the
United Nations was created. All of the great powers were
included (the U.S., Britain, France, China, and the Soviet
Union). Internationalism was extended to include Africa,
Asia, and Latin America.
In postwar Europe, tensions emerged between the Soviet Union
on the one hand and the United States and Britain on the
other. In a series of conferences during the end of the war,
spheres of influence within postwar Europe were established.
Western leaders conceded Soviet control of much of occupied
Eastern Europe, but insisted on a Germany divided among the
victorious Allies.
The United States occupied Japan, which lost its imperial
possessions. Korea, a former Japanese colony, was divided
between the Soviet Union and the U.S. Former European
colonies in Asia were briefly reestablished prior to
successful independence movements.
European colonialism in Africa, the Middle East, and India
was also shaken. The Soviet Union rapidly established
communist regimes in those Eastern European nations created
after World War I. Western Europe was free to reestablish
democracy, but under the watchful eye of the United States.
Increasingly, a bipolar world dominated by the United States
and the Soviet Union emerged.
- The Cold War and Decolonization, 1945-1989
The United States and Britain attempted to respond vigorously
to the expansion of the Soviet Union in Eastern Europe. In
1947, the U.S. announced the Marshall Plan, a program of
economic assistance to Europe. The Soviet Union viewed the
plan as a means of extending U.S. influence in Europe. The
major point of conflict was Germany. The U.S. intended to
reconstruct Germany as a viable political unit and a barrier
against further Russian expansion. When the Soviet Union
attempted to blockade the free city of Berlin, the U.S.
airlifted supplies to keep the city open. A series of
alliances developed.
The U.S. created NATO for Western Europe and provided most of
the military force for the alliance. The Soviet Union
countered with the formation of the Warsaw Pact. Following
the Soviet development of an atomic bomb in 1949, the United
States and the Soviets entered into a period typified by
increasing atomic arsenals in each nation. With Europe
stabilized between two major power blocs, tensions rose
elsewhere in the world. The Korean War initiated regional
conflict. The United States enunciated its intentions of
halting the advance of communism anywhere in the world.
Although crises emerged, only the Vietnam War resulted in
actual conflict.
After the 1950s, the pressures of the cold war began to
subside. Soviet leaders initiated negotiations with the
United States that limited the proliferation of nuclear
weapons. Europe began to chart a more independent economic
and diplomatic path. The end of colonialism resulted in the
creation of nations that remained outside the bipolar
framework of the cold war. Economic internationalism became
more prevalent in the 1970s and 1980s. The oil crisis of the
1970s produced a ripple effect that disturbed most Western
economies, but there were no major depressions.
Multinational corporations gained increasing influence. The
cold war came to an end, when the Soviet Union could no
longer respond to American military spending. When Ronald
Reagan sought to establish a more confrontational policy with
the Soviet Union, the Soviet Union collapsed in 1991.
- Period III: The 1990s and Beyond
The end of the Cold War and the completion of decolonization set up another 20th-century period in world history, one that may extend well into the 21st century. This period features the dominance of the United States, regional conflicts, the reassertion of regional identities, large trade blocs, and wdespread adoption of policies favoring freer market forces.
- Conclusion: A Legacy of Uncertainty
The combined effect of two world wars and a depression sapped
the vitality of Europe. European weakness led to a bipolar
world dominated by the United States and the Soviet Union.
European colonialism elsewhere in the world came to an end. With the collapse of the Soviet Union, the cold war ended, hastening the rebalancing of world power.
