FAQs on World War I - 1915 Video Lecture - UPSC Mains: World History

1. What were the main causes of World War I?
Ans. World War I was primarily caused by a combination of factors including militarism, alliances, imperialism, and nationalism. The arms race and military buildup among European powers, the formation of alliances between different countries, the competition for colonies and resources, and the strong sense of national pride and loyalty all contributed to the outbreak of the war.
2. How did the assassination of Archduke Franz Ferdinand lead to World War I?
Ans. The assassination of Archduke Franz Ferdinand of Austria-Hungary by a Serbian nationalist in 1914 served as a catalyst for the war. Austria-Hungary saw this act as a direct attack and issued an ultimatum to Serbia, which led to a series of events and declarations of war among different countries. The complex web of alliances and the escalation of tensions ultimately triggered the start of World War I.
3. What was the significance of trench warfare during World War I?
Ans. Trench warfare played a vital role in World War I as it became the dominant form of warfare on the Western Front. Trenches provided protection from enemy fire and created a stalemate situation where both sides were locked in a deadly and protracted struggle. The conditions in the trenches were harsh, with soldiers facing constant danger from artillery, machine guns, and diseases. This type of warfare led to a significant loss of life and a long-lasting impact on military strategies.
4. How did the United States become involved in World War I?
Ans. The United States initially adopted a policy of neutrality when World War I broke out in 1914. However, several factors led to its eventual involvement. These included unrestricted submarine warfare by Germany, the sinking of the British ocean liner Lusitania with American passengers on board, and the interception of the Zimmermann Telegram, which revealed Germany's attempt to form an alliance with Mexico against the United States. These incidents sparked public outrage and eventually prompted the United States to declare war on Germany in 1917.
5. What were the consequences of World War I?
Ans. World War I had far-reaching consequences on a global scale. It resulted in the loss of millions of lives, the redrawing of national borders, and the collapse of empires. The Treaty of Versailles, which ended the war, imposed heavy reparations on Germany and set the stage for future conflicts. The war also led to significant social and cultural changes, including advancements in technology, the women's suffrage movement, and the rise of new political ideologies such as communism and fascism.
