18791940

18791940 refers to the period between 1879 and 1940, a span that includes the late stages of the Second Industrial Revolution and the early decades of the 20th century. It was characterized by rapid change in economies, technologies, and social structures, setting the stage for much of modern global life.

The era witnessed significant industrial and technological transformation: electrification and the expansion of chemical industries reshaped production; mass production and new transport and communication networks accelerated economic growth. The spread of automobiles, aircraft, radio, and improved telegraph systems facilitated greater connectivity and urbanization, contributing to a more interconnected world.

Politically and militarily, the period experienced major upheavals. World War I (1914–1918) altered national borders and global power dynamics, followed by the Russian Revolution of 1917 and the subsequent formation of new states and ideologies. The interwar years saw attempts to construct a new international order, but also economic instability and the Great Depression after 1929. The rise of totalitarian movements in some countries and conflicts in various regions further reshaped global politics.

Science, culture, and society also evolved. In physics, relativity and quantum theory emerged; advances in medicine, chemistry, and agriculture improved living standards. The period witnessed significant cultural shifts, including modernist movements in art and literature, and expansions in social rights such as women’s suffrage in different regions.

The era effectively ends around 1940, as World War II escalates and redraws international alignments. The period left lasting legacies in political borders, economic systems, technology, and international institutions that continued to influence global affairs in the subsequent decades.
