1. The Great War
World War I

2. Causes of the War
The rise of Germany as a great power changed the balance of power in Europe, the alliance systems that developed attempted to deal with this but turned Europe into two armed camps.
Nationalist unrest caused conflict and internal divisions.
Arms race contributed to tensions.

3. The Alliance Systems The Three Emperors League
The key to German preeminence was keeping France isolated.
Bismarck negotiated an alliance in 1872 (Dreikaiserbund).
The alliance joined Germany, Austria, and Russia to cooperate to maintain peace and the status quo.

4. The Russo-Turkish War
After revolt in Turkish controlled Bulgaria in 1876, Russia went to war with the Ottomans.
The Treaty of San Stefano (1878) established Serbia, Montenegro and Rumania as states and autonomy to Bulgaria.
The increased influence of Russia in the Balkans and the Mediterranean threatened Austrian and British interests.

5. Congress of Berlin Powers met to avoid war in Berlin in 1878.
The Treaty of Berlin reduced Russian influence in the region by giving Austria domination of Bosnia and the British control of Cyprus.
The compromise avoided war, but angered the Russians by reducing their war gains.

6. The Alliance Systems The Dual Alliance Revival of the Three Emperors
The Austro-Russian conflict ended the Three Emperors’ League.
Bismarck created an alliance with Austria in 1879.
Revival of the Three Emperors
Bismarck continued negotiations and revived the league in 1881, this again ended in 1887.

7. The Alliance Systems The Triple Alliance (1882)
Italian anger over French control over Tunisia made them ally with Germany and Austria.
Germany’s alliances with Austria, Russia, Italy and good relations with UK isolated France.
Franco-Russian Alliance
With the dismissal of Bismarck, Germany did not renew its alliance with Russia.
In 1894, France negotiated and secret alliance with Russia, primarily aimed at Britain in the Med.

8. Anglo-German Relations
In the 1890s, relations between Germany and Britain began to deteriorate.
Germany’s support for the Boers in South Africa angered the British.

The Entente Cordiale was negotiated in 1904, leading to increased cooperation.
Italian-French Agreement
Italy and France came to an secret agreement on colonial policy in North Africa.
This further weakened Germany’s position.

10. The First Moroccan Crisis
Germany provoked a crisis with France over French protectorate in Morocco.
German calls for Moroccan independence were denied by Britain, Russia, and Italy at the Algeciras Conference in 1906.
Germany’s belligerent attitude brought France, Britain and Russia closer together.

11. The Alliance Systems Anglo-Russian Entente Triple Entente
Britain and Russia came to an agreement on their spheres of control in Central Asia in 1907
Triple Entente
The agreement between Britain and Russia completed the process of alliances between the two nations and France.

12. The Bosnian Crisis
Austria wished to annex Bosnia and came to an agreement with Russia that gave them control of the Turkish straits in 1908.
The Austrians moved too fast and angered the Russians and the Serbians who hoped to annex Bosnia themselves.
Germany pledged to support Austria and Russia backed down in the spring of 1909.

13. The Second Moroccan Crisis
In 1911, Germany again opposed the creation of a French Moroccan protectorate.
The French and Germans came to a territorial agreement which eased tensions.
In 1912, the British began concentrating their navy in the North Sea and the French in the Mediterranean to deal with the German threat.

14. The First Balkan War
Italy’s defeat of Turkey in war in 1912 gave encouragement to Balkan states.
Bulgaria, Serbia, Montenegro, and Greece formed the Balkan League and went to war with Turkey in 1912.
The 1913 Treaty of London had Turkey lose all of its European territory (except on the straits) and the creation of Albania (against Russian and Serbian objections).

15. The Second Balkan War

17. The Outbreak of War
Austria made diplomatic demands that the Serbs could not accept (though they were willing to negotiate).
Austria was determined to deal with Serbia and declared war on July 28, 1914.
Germany had given Austria a “blank check” of support in the matter and appeared ready to go to war.

18. The Outbreak of War
Russia was not going to let its ally in the Balkans, Serbia, be defeated. So Tsar Nicholas II began mobilizing on July 30.
Germany demanded the Russians halt. When they refused, Germany declared war on Russia on August 1.

19. The Outbreak of War
Germany asked France its intentions. The French said they would follow their interests.
On August 3rd, Germany declared war on France.
The Germans, going by the Schlieffen Plan, invaded neutral Belgium to quickly defeat France before Russia could mobilize.
In response, Britain declared war on Germany on August 4th.
So began the Great War.

20. Europe on the Eve of World War I

21. Unexpected yet inevitable
Most early 20th century Europeans believed an all out European war was unlikely.
Economic growth and interdependence in trade and finance brought European states and the entire world closer than ever before.
Communications, advances in travel and tourism allowed people to appreciate other nations and cultures.

22. Unexpected yet inevitable
Despite growing interdependence, no international organization existed to diffuse crises (each state was sovereign.)
Most European nations increased the size of their armies, navies, and armaments.
Nations planned for war an instituted mandatory service requirements.
With heightened nationalism, most people welcomed war in 1914 in euphoria and the belief in quick victory (and little knowledge of war’s effects).

23. A War on Two Fronts
The Germans faced a war on two fronts on opposite sides of their nation; against Britain and France in the west and Russia in the East.

24. The Schlieffen Plan
The German plan was developed by Alfred Graf von Schlieffen in 1905 in the event of a war against France and Russia.
It called for invasion of neutral Belgium and a defeat of France by taking Paris in 6 weeks.
The Russians would be slow to mobilize, so Germany could then move its troops to the east.

26. War in the West Failure of the Schlieffen Plan
German General Helmuth von Moltke led his troops through a heavily defended area of Belgium, slowing their advance.
The British forces sent to help the French further slowed the German advance.

In 1915, the war in the west settled into a stable front the stretched from the Swiss border to the North Sea coast.

29. Trench Warfare
With the stability of the front lines, the war moved into trenches dug by armies on both sides, stretching for over 500 miles.

30. Trench Warfare
Soldiers lived in the trenches for weeks faced with filth, rats, regular artillery attacks, and the danger of poison gas attacks.

31. Trench Warfare
A “no-man’s-land” existed between the trenches of the two armies.
Soldiers would go “over the top” of their trenches and attempt to storm the other line, often being cut down by machine gun fire.

Many still were however when they attempted to charge enemy lines.

All other nations soon followed in using gas in war.

36. Impact of New Technology Tanks
Tanks were first used by the British in the Battle of the Somme in 1916.
The early tanks were to slow and not well armed, but they foretold how tanks could be used as weapons in the future.

37. Impact of New Technology Airplane
The introduction of the airplane allowed for reconnaissance of enemy positions, bombing of enemy positions, and the first air-to-air combat known as “dog fighting.”

38. Air Ace - The Red Baron

He had over 80 victories.

They turned to propaganda to do this.

51. Propaganda

German foreign minister Zimmerman had proposed to Mexico to attack the United States, in which in would receive the U.S. Southwest and prevent U.S. entry in the European War.
This enraged public opinion, and in April, 1917 the U.S. declared war on Germany.
