Conflicts

The 20th century was defined by two massive global wars and a long-standing ideological struggle between superpowers. These conflicts redrew the map of the world, led to the creation of international organizations like the UN, and advanced military and civilian technology at an unprecedented pace.

• World War I (1914-1918): The "Great War"; ended the era of empires.
• World War II (1939-1945): The largest and deadliest conflict in human history.
• The Cold War (1947-1991): Ideological battle between Capitalism (USA) and Communism (USSR).
• Decolonization: Wars and movements for independence in Asia and Africa.

• The Treaty of Versailles (1919) officially ended WWI and imposed heavy penalties on Germany, often cited as a cause for WWII.
• The League of Nations was the precursor to the United Nations, established after WWI to prevent future conflicts but ultimately failing.
• Hiroshima and Nagasaki (Japan) were the first and only cities to be targeted by atomic bombs (August 1945).
• The Marshall Plan was a US initiative to provide economic aid to Western Europe to help rebuild after WWII and prevent the spread of communism.
