Review Questions

• Compare and contrast the causes of World War I and World War II.
  • The causes of World War I largely revolved around nationalism, militarism, and a tangled system of alliances that escalated a regional conflict into a global war. In contrast, World War II's origins can be traced to unresolved issues from World War I, such as the harsh conditions of the Treaty of Versailles, which fostered resentment in Germany. Additionally, economic instability during the Great Depression contributed to the rise of totalitarian regimes in Germany and Italy, directly leading to their aggressive expansionist policies.
• Evaluate the impact of the World Wars on global political structures and alliances.
  • The World Wars fundamentally altered global political structures by dismantling empires and establishing new nation-states. After World War I, empires like Austria-Hungary and the Ottoman Empire dissolved, leading to redrawn borders and new political entities. After World War II, the emergence of superpowers, primarily the United States and the Soviet Union, created a bipolar world order that defined international relations for decades. This shift also laid the groundwork for modern international organizations like NATO and the UN.
• Assess how the economic impacts of both World Wars influenced social changes in the post-war periods.
  • The economic impacts of both World Wars led to significant social changes during their respective post-war periods. After World War I, many nations faced economic hardships that spurred movements for social reform, including labor rights and women's suffrage as women entered the workforce in unprecedented numbers. In the aftermath of World War II, wartime production had transformed economies, leading to post-war booms. This period also saw increased government involvement in economies through welfare programs aimed at rebuilding societies, ultimately reshaping class dynamics and improving living standards.
