Timeline World Politics Since 1945
World Politics
Since 1945
A condensed timeline of the macro events that shaped the international order — from the Cold War to the fractures of today.

1945
Post-War Order
1945
United Nations Founded
San Francisco Conference establishes the UN. The five Allied powers become permanent Security Council members — a veto structure that endures to this day.
1947
Cold War Begins — Truman Doctrine
The US declares it will contain Soviet expansion anywhere. The world divides into two ideological blocs. This binary logic governs global politics for the next four decades.
1947
Marshall Plan
$13 billion in US aid rebuilds Western Europe. Ties European economies firmly to the American orbit and prevents communist political gains in war-ravaged nations.
1947
Indian Independence & Partition
Britain exits the subcontinent. India and Pakistan emerge as separate states. The partition displaces 15 million people and inaugurates decades of subcontinental rivalry.
1949
High Cold War
1949
NATO Founded
Western military alliance formalises US commitment to European defence. The USSR responds with the Warsaw Pact in 1955. Europe becomes the primary Cold War chessboard.
1949
Communist Revolution in China
Mao's forces defeat the Nationalists. The People's Republic is declared. The "loss" of China shocks Washington and deepens anti-communist paranoia in American politics.
1950–53
Korean War
The first hot proxy war of the Cold War. US and UN forces fight Chinese and North Korean troops. Ends in armistice, not peace — the peninsula remains divided at the 38th parallel.
1955
Bandung Conference — Non-Aligned Movement
29 newly independent Asian and African states meet in Indonesia. Nehru, Nasser, Sukarno articulate a "third way" between the two blocs. Decolonisation enters world politics as a structural force.
1956
Suez Crisis
Britain and France invade Egypt after Nasser nationalises the Suez Canal. The US forces them to withdraw. Europe's imperial era ends. American and Soviet power are confirmed as the only poles.
1962
Cuban Missile Crisis
Thirteen days in October bring the world closest to nuclear war. Kennedy and Khrushchev negotiate a back-channel resolution. Mutual Assured Destruction becomes the cornerstone of superpower relations.
1965–75
Vietnam War
The US fights communist North Vietnam in its costliest Cold War intervention. 58,000 Americans and over a million Vietnamese die. Saigon falls in 1975. American power is revealed to have limits.
1970s
Détente & Crisis
1972
Nixon Opens China
Nixon visits Beijing, ending 23 years of US-China estrangement. A strategic masterstroke — driving a wedge between China and the USSR. The foundations of today's great-power triangle are laid.
1973
Oil Shock
OPEC Arab states embargo oil exports in response to US support for Israel. Prices quadruple. The West faces recession and queues at petrol stations. Energy becomes a permanent geopolitical weapon.
1979
Soviet Invasion of Afghanistan
Moscow's Vietnam. The CIA arms the Mujahideen. A decade of brutal fighting ends with Soviet withdrawal in 1989. Afghanistan's ruination — and the radicalisation of Islamist fighters — has consequences for decades.
1979
Iranian Revolution
The Shah falls. Ayatollah Khomeini returns. Iran becomes an Islamic Republic, hostile to both superpowers. A new force — political Islam — enters the stage of global politics.
1985
End of the Cold War
1985
Gorbachev — Glasnost & Perestroika
The new Soviet leader opens the political and economic system. Reformist intentions spiral beyond control. The loosening of the grip sets Eastern Europe in motion.
1989
Fall of the Berlin Wall
Communist governments collapse across Eastern Europe in a cascade of revolutions. The Wall falls on 9 November. Fukuyama declares "the end of history." Liberal democracy appears to have won unconditionally.
1991
Dissolution of the Soviet Union
The USSR formally dissolves on 25 December. Fifteen new states emerge. The US becomes the world's sole superpower. The unipolar moment begins — and with it, dangerous overconfidence about American primacy.
1991
The Unipolar Moment
1991
Gulf War
US-led coalition expels Iraq from Kuwait. Demonstrates overwhelming American military power. Leaves Saddam in place — a decision that shapes the next decade.
1992–95
Bosnian War & Rwandan Genocide
Europe sees its worst atrocities since 1945. Rwanda loses 800,000 in 100 days while the world watches. The limits of the new world order are exposed. "Never again" is said again.
1994
NAFTA & WTO — Globalisation Peaks
Free trade agreements and the formation of the WTO in 1995 accelerate economic integration. Capital and goods flow freely. The political backlash takes two decades to arrive — but it does arrive.
1997
Asian Financial Crisis
Currency crises sweep Thailand, South Korea, Indonesia. The IMF imposes brutal austerity conditions. Asia learns that Western-led financial institutions serve Western interests. China draws its own conclusions.
2001
The War on Terror
2001
September 11 & the Afghan War
Al-Qaeda attacks the United States. 3,000 die. Within weeks the US invades Afghanistan and topples the Taliban. The war lasts twenty years. The Taliban return to power in 2021.
2003
Iraq War
The US and UK invade Iraq on false pretexts of WMDs. Saddam is toppled. The country collapses into sectarian war. The invasion destabilises the entire Middle East and fatally damages US credibility.
2008
Global Financial Crisis
Wall Street collapses. Governments bail out banks. The working and middle classes bear the cost. Faith in liberal market economics begins its long erosion. Populism has its origins here.
2010
Multipolar Fracture
2010–12
Arab Spring
Mass uprisings topple governments in Tunisia, Egypt, Libya, Yemen. Social media plays a catalytic role. Most transitions end in civil war, military rule, or chaos. Syria descends into the decade's worst humanitarian disaster.
2012
Xi Jinping Takes Power
Xi consolidates control of the Chinese Communist Party. He abandons the "hide and bide" foreign policy of Deng's era. China will assert itself — in the South China Sea, on Taiwan, in global institutions.
2014
Russia Annexes Crimea
Following Ukraine's Euromaidan revolution, Russia seizes Crimea and backs separatists in the Donbas. The post-Cold War European order is broken for the first time. Sanctions begin; deterrence fails.
2016
Brexit & Trump
Britain votes to leave the EU. Donald Trump wins the US presidency. Populist nationalism enters power in the core Western states simultaneously. The liberal international order loses its two most powerful architects.
2017
US–China Trade War Begins
Trump imposes tariffs on Chinese goods. The era of unchallenged globalisation ends. Technology decoupling, supply chain reshoring, and great-power competition replace the consensus of the 1990s.
2020
The Polycrisis
2020
COVID-19 Pandemic
A virus from Wuhan kills millions and shuts the world economy. Supply chains fracture. Borders close. State power expands overnight. The pandemic accelerates every existing trend — inequality, nationalism, distrust of institutions.
2022
Russia Invades Ukraine
Full-scale invasion on 24 February. The largest land war in Europe since 1945. NATO unity is tested and largely holds. Russia is isolated but not defeated. The war redraws European security permanently.
2023
Hamas Attack & Gaza War
Hamas kills 1,200 Israelis on 7 October. Israel's military response kills tens of thousands in Gaza. The Global South and the West divide sharply in their responses. The UN fractures along familiar lines.
2024
Year of Elections — Democracy Under Strain
Over 4 billion people go to the polls across 50+ countries. Incumbents lose everywhere. Trump returns to the White House. Far-right and nationalist parties gain across Europe. The post-war consensus continues to erode.
2025–26
New World Disorder
US retrenchment from NATO and multilateral institutions accelerates under Trump's second term. China and Russia deepen ties. The BRICS bloc expands. No single order governs the world — only competing spheres. History, it turns out, did not end.
