Middle AgeIn the history of Europe, the Middle Ages (or medieval period) lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages.
Modern AgeIn the linear, global, historiographical approach, modern history (the "modern period," the "modern era," "modern times") is the history of the period following post-classical history (in Europe known as the "Middle Ages"), spanning from about 1500 to the present. "Contemporary history" includes events from around 1945 to the present. (The definitions of both terms, "modern history" and "contemporary history", have changed over time, as more history has occurred, and so have their start dates.
Contemporary AgeContemporary history is politically dominated by the Cold War (1945–91) between the United States and Soviet Union whose effects were felt across the world. The confrontation, which was mainly fought through proxy wars and through intervention in the internal politics of smaller nations, ultimately ended with the dissolution of the Soviet Union and Warsaw Pact in 1991, following the Revolutions of 1989.
Ancient AgeAncient age refers to ages nearing or surpassing the life expectancy of human beings, and is thus the end of the human life cycle. Terms and euphemisms include old people, the elderly (worldwide usage), seniors (American usage), senior citizens (British and American usages), older adults (in the social sciences), and the elders (in many cultures—including the cultures of aboriginal people) From 3000 BF - 476 BF
