The postwar economic boom ended as OPEC nations imposed oil embargoes on Western countries, triggering energy shortages and inflation. Simultaneously, Cold War rivalries and the legacy of colonialism fueled armed conflicts across Southeast Asia, the Middle East, Latin America, and Africa, while social progressive movements from the 1960s continued to reshape Western societies.
The 1970s were defined by oil-driven stagflation, widespread decolonization struggles, and Cold War proxy conflicts. Technological breakthroughs such as the Intel 4004 microprocessor transformed computing, while political revolutions—including Iran's Islamic Revolution and Chile's coup—restructured governments. China's international recognition, the Yom Kippur War, and the Soviet invasion of Afghanistan reshaped global geopolitics across the decade.
The decade produced a lasting shift from Keynesian toward neoliberal economic policy, first applied under Chile's post-coup government and later adopted broadly in the West. Computing entered the consumer era, laying groundwork for the personal computer revolution. The Iranian Revolution and Soviet-Afghan War set trajectories that dominated international affairs for decades, while African and Asian decolonization reshaped the post-colonial world order.
