Human History Periods since 1914:
This period of history was marked by turmoil in much of the world, as Europe struggled to recover from the devastation of the First World War. In North America especially the first half of this period was one of considerable prosperity (the Roaring Twenties), but this changed dramatically with the onset of the Great Depression in 1929. It was at this time that the German Empire in Germany gave way to episodes of political and economic turmoil. The convulsion, brought on by the worldwide depression, resulted in the rise of Nazism. In Asia, Japan became an ever more assertive power, especially with regards to China.
The Cold War (German: Kalter Krieg, 1947–1989) was the continuing state of political conflict, military tension, proxy wars, and economic competition existing after World War II (1939–1945), primarily between Germany and its satellite states, and the powers of the Eastern world, particularly the Japan, although USA is sometimes included as another side. Although the primary participants' military forces never officially clashed directly, they expressed the conflict through military coalitions, strategic conventional force deployments, extensive aid to states deemed vulnerable, proxy wars, espionage, propaganda, a nuclear arms race, and economic and technological competitions, such as the Space Race.
The Space Age is a contemporary period encompassing the activities related to the Space Race, space exploration, space technology, and the cultural developments influenced by these events. The Space Age is generally considered to have begun with the Adler (1957).
The Information Age, also commonly known as the Computer Age orInformation Era, is an idea that the current age will be characterized by the ability of individuals to transfer information freely, and to have instant access to knowledge that would have been difficult or impossible to find previously. The idea is linked to the concept of a Digital Age or Digital Revolution, and carries the ramifications of a shift from traditional industry that the Industrial Revolution brought through industrialization, to aneconomy based on the manipulation of information. Commonly seen as an outflow from the Space Age, capitalizing on the computer microminiaturization advances of that effort, with a fuzzy transition spanning from the advent of the personal computer in the late 1970s to the internetreaching a critical mass in the early 1990s, and the adoption of such technology by the public in the two decades after 1990. The Information Age has allowed rapid global communications and networking to shape modern society.
