1910s1970s

The term 1910s1970s denotes a broad historical span from the 1910s through the 1970s, a period marked by upheavals and rapid change in politics, society, and technology. It includes two world wars, the emergence of new international institutions, and major shifts in daily life worldwide.

The 1910s witnessed World War I (1914–1918), the collapse of several empires, and the Russian Revolution of 1917, which introduced communist governance in parts of Eurasia. The 1920s brought relative peace and modernization for some, but also economic volatility and social experimentation. The 1930s were defined by the Great Depression and the rise of authoritarian movements in Europe and elsewhere.

World War II (1939–1945) was a global conflict that redefined borders, accelerated technological innovations, and led to the founding of the United Nations. The postwar era reshaped international power dynamics through the Cold War, reconstruction, and decolonization movements across Africa, Asia, and the Caribbean.

From the 1950s to the 1970s, societies experienced rapid economic development, urbanization, and cultural change. Civil rights movements, feminist activism, and student movements challenged established norms. Technological advances in aviation, computing, space exploration, and communications transformed everyday life, while environmental awareness and energy concerns influenced policy and industry.
