18791925

18791925 designates the historical span from 1879 through 1925, a period that stretches from the late 19th century into the early 20th century. It covers the mature phase of the Second Industrial Revolution, rapid urbanization and globalization, and the political shifts that accompanied imperial expansion and rising mass politics.

Technological and scientific change accelerated: 1879 saw the practical electric light bulb, enabling new urban life, while electricity, the internal combustion engine, railways, aviation, and telecommunications transformed economies and societies in the ensuing decades. The early 20th century also produced advances in physics, medicine, and engineering.

The political landscape shifted dramatically. National rivalries among colonial powers and emergent nation-states fed competition and conflict. World War I (1914–1918) radically altered borders, economies, and political systems. The Russian Revolution of 1917 led to the creation of the Soviet Union in 1922. The postwar settlement produced the Treaty of Versailles (1919) and the League of Nations (1920).

Social and cultural currents reshaped societies: expanding suffrage, labor rights, and education broadened political participation in many countries. The 1918–1919 influenza pandemic caused widespread mortality. The 1920s saw financial experimentation and stabilization efforts, including the Dawes Plan (1924) to address German reparations, and a flourishing of modernist art and culture in many regions.

The era's legacies include changes in geopolitics, economics, and culture that influenced the interwar period and set the conditions for future upheavals and reforms.
