Imperialism: Definition and Global Impact

Imperialism: The takeover of a country or territory by a stronger nation with the intent of dominating the economic, political, and social life of the people of that nation.

Consequences of Imperialism

  • Obligation to convert
  • Indoctrination
  • Loss of life
  • Loss of language and natural resources
  • Loss of identity

The First World War (1914–1918)

The First World War began on July 28, 1914, and ended on November 11, 1918. It was an armed confrontation on a world scale in which the most developed countries—the great industrial and military powers of Europe—participated. Later, the colonized countries of Africa and the United States, among others, would be added.

Phases of WWI

  1. 1914; War of Movements: A German plan was made (the Schlieffen Plan) which was based on a rapid attack on France through neutral Belgium. After defeating France, German troops could turn about and attack Russia, a backward country that would need a long time to mobilize its troops.
  2. 1915–1916; The War of Attrition: The stalemate on the Western Front led to a new sort of warfare: the war of attrition. This is a military strategy in which a belligerent side attempts to win a war by wearing down its enemy to the point of collapse through continuous losses in personnel and materiel.
  3. 1917; The Turning Point of the War: The Zimmermann Telegram was a 1917 diplomatic proposal from the German Empire to Mexico to make war against the United States. The proposal was intercepted and decoded by British intelligence. The revelation of the contents outraged American public opinion and helped generate support for the United States’ declaration of war on Germany in April 1917.
  4. 1918; The End of the War

Causes of WWI

  • Militarism: A policy of building up a strong military to prepare for war.
  • Alliances: Agreements between nations to provide aid and protect one another.
  • Nationalism: Extreme pride in one’s country.
  • Imperialism: When one country takes over another country economically and politically.
  • Assassination: The assassination of Austrian Archduke Franz Ferdinand.

Consequences of WWI

  • Terrible loss of life: eight million dead and millions of wounded people.
  • The USA became the first world power, while Europe started a long decadence.
  • The mass mobilization of men led to the incorporation of women into the workforce.
  • The Soviet Revolution and the spread of a prerevolutionary climate in Europe.
  • Exacerbated nationalism and the fear of a communist revolution.

Significant Peace Treaties

  • The Treaty of Versailles was a peace treaty signed at Versailles at the end of the First World War by more than fifty countries. This treaty officially ended the state of war between the Germany of the Second Reich and the Allies of the First World War.
  • The Treaty of Berlin was the main and initial act of the Congress of Berlin, by which the United Kingdom, the Austro-Hungarian Empire, France, the German Empire, the Kingdom of Italy, Russia, and the Ottoman Empire of Sultan Hamid revised the Treaty of San Stefano signed on March 3 of that same year.
  • The Treaty of Trianon was a peace treaty signed after the First World War between the Allies and the Kingdom of Hungary on June 4, 1920. It was signed in the Grand Palace of Trianon, France.
  • The Brest-Litovsk Treaty was a peace treaty signed on March 3, 1918, in the Belarusian city of Brest-Litovsk between the German Empire, Bulgaria, the Austro-Hungarian Empire, the Ottoman Empire, and Soviet Russia.

The Russian Revolution

The Russian Revolution encompasses all the political, social, and economic events that culminated in the overthrow of the Tsarist regime and established the Leninist regime in 1917, between February and October. This revolution was made possible, among other things, by the weakening of the army during the First World War.

The historical importance of the Russian Revolution lies in the fact that it was commanded, in the first place, by workers and soldiers; it was the people who overthrew the dynasty of the Tsars, a fact that resulted in the fall of absolutism and the implementation of a communist government. In this way, the working class guided Russia’s policy.

Causes of the Russian Revolution

  • Policies of the Czars: The last absolute king, Nicholas II, became Tsar in 1884, ruling by divine right without a democratic government.
  • Industrialization and Economic Growth: Russia was the most backward in Europe. Agriculture was the main economic activity, and there was little industrialization.
  • The Russo-Japanese War: Russia lost this conflict.
  • Bloody Sunday: A peaceful protest where troops opened fire on the crowd.
  • World War I: This broke the Russian economy, showed the weakness of the Tsar, and killed thousands of people. Russia eventually accepted the Peace of Brest-Litovsk, ending WWI with Germany.
  • March Revolution: Led by Lenin, the Bolsheviks accepted the Peace of Brest-Litovsk. Economic reforms included the New Economic Policy (NEP), alongside various political reforms.

Consequences of the Russian Revolution

  • Overthrow of the absolute monarchy of the Tsars.
  • The rise of Russia’s power globally in scientific, economic, political, and military fields.
  • The establishment of communism, with the creation of the Communist Federative Republic, which was renamed the Union of Soviet Socialist Republics (U.S.S.R.).
  • The division of the world in two: on one side was Capitalism and on the other, Communism. This opposition resulted in the Cold War.
