According to a common periodization scheme, the modern era is the third of the major historical epochs after antiquity and the Middle Ages and extends to the present. In historiography, the beginning of the modern era is considered to be the turn of the 15th and 16th centuries, which is perceived as a turning point in several respects, with a certain temporal range - and especially from a European perspective.
Examples of epochal turning points are the Ottoman conquest of Constantinople in 1453, the discovery of America in 1492 and the Reformation initiated by Martin Luther in 1517. From the point of view of cultural history, the Renaissance, humanism and the development of printing in Europe with movable type stamps can also be regarded as turning points. In the sense of a unification of the different levels of observation, the round year 1500 has become customary by historians for the dating of the beginning of the modern era.
Epochs within modern history that follow the Age of Discoveries, early colonialism, and the Reformation and Counter-Reformation are, in Europe, the era of the Thirty Years' War and the Age of Enlightenment; on a global scale, the spread of the Industrial Revolution, the "long" 19th century with the era of imperialism, and the "short" 20th century (with the two world wars, the Holocaust, and the nuclear standoff), which has passed into contemporary history.
The special characteristics of the modern era in contrast to earlier epochs of human history include reduced birth rates with extended life expectancy, an accelerated change in economic and social conditions as well as the globalization of transport connections, economic contexts and communication possibilities. Scientific knowledge, revolutionary upheavals, capitalist economic structures and the democratic striving for freedom are significant as accelerating factors of modern change. The modern optimism of progress, which has dominated for a long time, is subjected to critical reflection in view of humanitarian setbacks and unsolved human problems, such as those associated with the climate crisis.
