6. Today’s Sponge Identify MAIN causes of World War I
Militarism: building up a country’s army, navy and military to gain military dominance over your rivals
Alliance System: “entangling” alliances
Imperialism: the actions used by one nation to exercise political and/or economic control over a smaller or weaker nation
Nationalism: loyalty or devotion to a nation

7. Causes of World War I: Imperialism
In the 19th century, a new phase of Western expansion into Asia and Africa began.
European nations began to view Asian and African societies as a source of industrial raw materials and a market for Western manufactured goods.
In this era, products of European factories were sent to Africa, Asia, and Latin America in return for oil, tin, rubber, and the other resources needed to fuel European industry and economy.

8. Causes of World War I: Imperialism
Imperialism is defined as the extension of a nation’s power over other lands.
The imperialism of the late 19th century was referred to as the “new imperialism.”
imperialism went beyond the establishment of trading posts in these regions.
Now European countries sought direct control over these territories.

9. Causes of World War I: Imperialism
Imperialism was tied to Social Darwinism and racism.
Social Darwinists believed that in the struggle between nations, the fit are victorious.
Europeans believed that they were racially and culturally superior to non-European people of the world.

10. By the late 1800s, nationalism, or a feeling of intense pride of one’s homeland, had become a powerful idea in Europe.
Nationalists place primary emphasis on promoting their homeland’s culture and interests above those of other countries.
One of the basic ideas of nationalism is the right to self-determination—the idea that who people belong to a nation should have their own country and government.

11. Nationalism
In the 1800s, nationalism led to a crisis in southeastern Europe in the region known as the Balkans.
once ruled by the Ottoman Empire and Austria-Hungary
As nationalism became a powerful force in the 1800s, the different national groups within these empires began to press for independence.
Serbia was one of the first nations of this region to obtain its independence
Russia supported the Serbs, Austria-Hungary wanted to limit its growth.

12. Militarism
Militarism means that the army and military forces are given a high profile by the government.
The growing European divide had led to an arms race between the main countries.
The armies of both France and Germany had more than doubled between 1870 and 1914 and there was fierce competition between Britain and Germany for mastery of the seas.

13. Militarism: the Naval Race
In the late 1890s, the Germans began building a navy challenging Great Britain’s historical dominance at sea.
By the early 1900s, an arms race had begun between Great Britain and Germany.

14. Militarism and World War I
The British had introduced the 'Dreadnought', an effective battleship, in 1906.
The Germans soon followed suit introducing their own battleships. The German, Von Schlieffen also drew up a plan of action that involved attacking France through Belgium if Russia made an attack on Germany. 

15. The Alliance System
In the 1860’s, Prussia—a German kingdom—launched a series of wars to unite the various German states into one nation. By 1871, Prussia had succeeded and the German Empire was born.
France and Germany quickly became enemies. To help unify Germany, the Prussians had attacked and defeated France in 1870, forcing the French to give up territory along the German border.
To defend itself, Germany joined into an alliance with Italy and Austria-Hungary. This alliance became known as the Triple Alliance.

16. The Alliance System
--The formation of the Triple Alliance alarmed Russian leaders, who feared that Germany might expand eastward into Russia.
--Russia also feared Austria-Hungary, and feared it threatened southeastern Europe. The Russians also supported the Slavs of southeast Europe.
--In 1894, Russia and France-- recognizing their common interests and fears of German and Austria-Hungary--signed the Franco-Russian alliance.

17. World War I: the Balkan Crisis
In the late 1800s, nationalism led to a crisis in southeastern Europe—an area known as the “Balkans.”
As nationalism had become a powerful force in Europe, different national groups in these regions had begun to push for independence, including: the Serbs, Bosnians, Croats, and Slovenes.

18. Serbian Nationalism
The first of these people to obtain their independence were the Serbs, who formed a nation called Serbia between the Ottoman Empire and Austro-Hungarian state.
In 1908, Austria-Hungary annexed Bosnia, which at the time belonged to the Ottoman Empire. This infuriated the Serbs.

19. The European Continent Goes to War
In late June 1914, the heir to the Austro-Hungarian throne, the Archduke Franz Ferdinand, visited the Bosnian capital of Sarajevo.
A Serbian nationalist named Gavrilo Princip rushed his car and shot Franz Ferdinand and his wife to death.
The assassination occurred with the knowledge of Serbian officials who hoped to start a war that would destroy the Austro-Hungarian Empire.

20. Europe Goes To War
Following the assassination of Franz Ferdinand, the Austro-Hungarian government decides to crush Serbia in order to prevent Slavic nationalism from undermining its empire.
Austia-Hungary sought the support of Germany in case Russia entered the war in defense of Serbia
Serbia counted on Russia for support in the event of an attack; Russia counted on the support of France.
On July 28, 1914, Austria-Hungary declared war on Serbia. Russia mobilized its army in response. Germany declared war on Russia on August 1st. Two days later, it declared war on France. WWI had begun.

21. Europe Goes To War
At the start of WWI, Germany launched a massive invasion of France. When German troops advanced through neutral Belgium, Britain declared war on Germany.
Those fighting for the Triple Entente were called the Allies: France, Russia, and Great Britain; Italy joined in 1915.
German and Austria-Hungary , along with the Ottoman Empire and Bulgaria, formed the Central Powers.
