Knowra Periodization Periodization Periodization divides the past into named periods according to selected changes or interpretive frameworks. Its boundaries and labels reflect choices about which developments matter.
Historical chronology : The arrangement of past events in their temporal sequence. Periodization organizes chronology into stretches marked by selected features.
Ancient history : The study of societies and events in the distant past, commonly ending with the fall of the Western Roman Empire. Its conventional endpoint illustrates how a period boundary becomes established.
Eurocentrism : A worldview that treats Europe as the central reference point for interpreting history and culture. Europe-centered periods can misrepresent societies whose timelines followed different patterns.
Geological time scale : A system that divides Earth's history into eons, eras, periods, epochs, and ages using geological evidence. Its evidence-based formal boundaries offer a contrast with interpretive historical periods.
Historical turning point : An event or development judged to mark a significant change in historical direction. Turning points often provide the boundaries between named periods.
Middle Ages : The period of European history conventionally placed between antiquity and the early modern era. The label began as a retrospective division between classical antiquity and a renewed present.
World-systems theory : A framework explaining global history through relationships among core, semi-peripheral, and peripheral regions. It organizes historical change around global economic relations rather than European eras.
Anthropocene : A proposed geological epoch defined by substantial human influence on Earth's systems. Debate over its start date exposes the stakes of naming a new period.
Historical continuity : The persistence of institutions, practices, or conditions across time. Continuities complicate divisions that imply a sharp break between periods.
Renaissance : A European cultural movement, beginning in Italy, associated with renewed engagement with classical learning and arts. Its placement as a distinct era reflects a particular account of cultural change.
