20th century

The 20th century was a century that began on January 1, 1901 and ended on December 31, 2000. It was the tenth and final century of the 2nd millennium. It is distinct from the century known as the 1900s (sometimes written as 19XX), which began on January 1, 1900 and ended on December 31, 1999.

Dubbed the "short twentieth century", this century in human history was dominated by chain of events that heralded significant changes in world history as to redefine the era: World War I and World War II, nationalism and decolonization, the Cold War and Post-Cold War conflicts, cultural homogenization through developments in transportation and communications technology, world population growth, awareness of environmental degradation, ecological extinction and the birth of the Digital Revolution. It saw great advances in communication and medical technology that by the late 1980s allowed for near-instantaneous worldwide computer communication and genetic modification of life.

Overview

The century had the first global-scale total wars between world powers across continents and oceans in World War I and World War II. Nationalism became a major political issue in the world in the 20th century, acknowledged in international law along with the right of nations to self-determination, official decolonization in the mid-century, and nationalist-influenced armed regional-conflicts.
