World War II (1939–1945)

Chain of Causes:
Versailles humiliation → German economic collapse →
Hitler rises to power → Rhineland, Austria, Czechoslovakia annexed →
Poland invaded → UK and France declare war

Key Turning Points:
1941: Germany invades Soviet Union (Operation Barbarossa) — overextension of the front
1941: Pearl Harbor attack → United States enters the war
1942–43: Battle of Stalingrad — the tide turns against Germany
1944: D-Day landings in Normandy
1945: Atomic bombings → Japan surrenders

The Holocaust and Humanity’s Reckoning

6 million Jews, Roma, people with disabilities, and political prisoners murdered

Historical Lessons:
→ United Nations founded (1945): collective security system
→ Universal Declaration of Human Rights (1948): "Never Again"
→ Genocide Convention (1948): international law prohibiting mass atrocity

Nuremberg Trials:
→ Established the concepts of war crimes and crimes against humanity
→ "I was just following orders" rejected as a defense

The Cold War (1947–1991)

Ideological conflict: Capitalism (USA) vs Communism (USSR)

Key Events:
1947: Truman Doctrine — declared policy of containing communism
1948–49: Berlin Blockade
1950–53: Korean War (first hot war of the Cold War)
1962: Cuban Missile Crisis — the world on the brink of nuclear war
1969: Nixon's Détente (easing of tensions)
1979: Soviet invasion of Afghanistan
1989: Fall of the Berlin Wall
1991: Dissolution of the Soviet Union → end of the Cold War

The Cold War’s Significance for Korea

Division → Korean War → Armistice Agreement (1953)
→ Still an armistice, not a peace treaty
→ The only place where the Cold War has not yet truly ended

Decolonization and the Third World

Wave of independence across Asia and Africa after 1945:
1947: Indian independence and partition (India & Pakistan)
1948: Founding of Israel → start of the Middle East conflict
1949: Founding of the People's Republic of China
1960s: "Year of Africa" — wave of African independence
1975: Vietnam reunification

Challenges:
→ Arbitrary colonial borders disregarding ethnic boundaries → conflicts
→ Ongoing economic dependency inherited from colonialism
→ Non-Aligned Movement: a third path, aligned with neither the US nor the USSR

The Late 20th Century to the 21st Century

1990s:
→ End of Cold War → US unipolar moment
→ Breakup of Yugoslavia → civil war and ethnic cleansing
→ Rwandan Genocide (1994): 800,000 killed in 100 days

2001–2010s:
→ 9/11 attacks → wars in Afghanistan and Iraq
→ 2008 Financial Crisis → rise of China
→ Arab Spring (2010–11): pro-democracy movements across the Middle East

2020s:
→ COVID-19 pandemic → exposing the fragility of globalization
→ War in Ukraine: a return to Cold War dynamics?
→ US-China strategic competition: a new bipolarity?

Core Principles of Historical Thinking

1. Causal Reasoning:
   No event has a single cause.
   → Structural causes + triggering events + the intentions of key actors

2. Contextual Understanding:
   Do not judge the past by present-day values.
   → Understand events through the perceptions and conditions of the people who lived them

3. Multiple Perspectives:
   "Same event, different interpretations"
   → The history of the victors vs. the history of the subjugated

4. Learning from History:
   History doesn't repeat itself, but it rhymes.
   → Recognizing patterns → clues for anticipating the future

“Those who cannot remember the past are condemned to repeat it.” — George Santayana
