Question

what are the different impacts of wars during the first half of the 20th century

Answer 1

The 20th century was dominated by a chain of events that heralded significant changes in world history as to redefine the era: World War I and World War II, nuclear power and space exploration, nationalism and decolonization, the Cold War and post-Cold War conflicts; intergovernmental organizations and cultural homogenization through developments in emerging transportation and communications technology; poverty reduction and world population growth, awareness of environmental degradation, ecological extinction;[6][7] 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. The term "short twentieth century" was coined to represent the events from 1914 to 1991.
