Impacts of war on societies Notes

Impacts of War on Societies: How Do Wars Reshape Lives?

1. Wars don’t just redraw borders or replace leaders: they basically hit society’s reset button.
2. World War I and World War II were total wars, meaning entire populations (not just soldiers) got pulled into the chaos.
3. Civilians felt the impact through rationing, bombing, propaganda, and economies being redirected toward war.
4. These wars massively reshaped social structures, economies, political systems, and cultural attitudes.
5. Both conflicts permanently altered the global order, shifting power, alliances, and how nations understood themselves.
6. Basically: big wars don’t just end, they rebuild the world in a different shape.

1. Social Impacts: How War Changes People and Communities

Mass Death, Trauma, and Loss

1. WWI and WWII caused death on a scale no one had imagined.
   1. WWI: ~20 million dead
   2. WWII: >60 million.
2. Families lost fathers, sons, and entire generations of young men.
3. Psychological trauma increased dramatically: WWI introduced the term “shell shock,” while WWII produced widespread PTSD, especially among bombing survivors and concentration camp victims.

Women’s Roles and Social Change

1. With millions of men away fighting, women took over crucial jobs.
   1. WWI: women worked in munitions factories, transport, agriculture.
   2. WWII: women built tanks and aircraft, encrypted enemy messages (e.g., Bletchley Park), served as medics, mechanics, engineers.
2. This created long-term effects:
   1. Many countries extended voting rights to women after WWI.
   2. After WWII, women’s wartime contributions helped fuel later pushes for gender equality.

Refugees, Displacement, and Population Shifts

1. War uprooted millions:
   1. WWI caused mass movements in Eastern Europe and Armenia.
   2. WWII created the largest displacement in history: over 60 million refugees, including Holocaust survivors and civilians escaping the Eastern Front.
2. Entire ethnic groups were forced to relocate, permanently changing the cultural map of Europe.

2. Economic Impacts: Reshaping Work, Industry, and Resources

Total War Economies

1. Governments placed the entire economy under wartime control.
   1. Rationing controlled food and materials.
   2. Factories shifted to military production.
   3. Civilian industries were repurposed: car factories built tanks, typewriter companies built machine guns.

Destruction and the Cost of Rebuilding

1. WWI destroyed farmland and towns across France and Belgium.
2. WWII levelled entire cities: London, Berlin, Dresden, Tokyo, Warsaw, and Hiroshima were devastated.
3. Reconstruction required huge spending and international cooperation, like the Marshall Plan (1948), which helped rebuild Western Europe.

Technological Innovation

1. War speeds up technological development:
   1. WWI: tanks, chemical weapons, blood transfusion advances.
   2. WWII: radar, jet engines, penicillin, early computers, nuclear weapons.
2. Many of these technologies reshaped post-war life, medicine, communication, and industry.

3. Political Impacts: New Systems, New Borders, New Powers

Collapse of Old Empires

1. WWI ended four major empires:
   1. German, Austro-Hungarian, Ottoman, Russian.
   2. This created new nations and political instability.
2. WWII accelerated the end of colonial empires, as European powers were too weak to maintain overseas control.

Rise of New Superpowers and the Cold War

1. After WWII:
   1. The USA and USSR emerged as superpowers.
   2. Europe was no longer the centre of global power.
   3. The world divided into two ideological blocs, beginning the Cold War.

Growth of International Organisations

1. WWI → League of Nations (failed due to weak enforcement).
2. WWII → United Nations (still central to global diplomacy).
3. These organisations reflected the belief that international cooperation was necessary to prevent future wars.

4. Cultural Impacts: How War Changes Ideas and Identity

Art, Literature, and Memory

1. War influenced creative expression:
   1. WWI artists portrayed disillusionment, loss, and destruction.
   2. WWII produced diaries (Anne Frank), films, propaganda, and Holocaust testimonies.
2. Cultural memory helps societies process trauma and understand their history.

Changes in National Identity

1. Germany after WWI felt humiliated, which contributed to the rise of Nazism.
2. After WWII, Germany had to confront responsibility for war crimes.
3. Many countries redefined themselves through rebuilding, remembrance, or new political systems.

5. Long-Term Consequences: A New World Emerges

1. Wars permanently changed the 20th century:
   1. Women’s rights expanded
   2. Workers gained protections
   3. Welfare states grew
   4. More countries demanded independence
   5. Global organisations strengthened cooperation
   6. The Cold War reshaped international politics
   7. Human rights gained new urgency after WWII
2. War destroys - but it also forces societies to rebuild, rethink, and reform.
