6. Change and Continuity
- Continuity and Change are interwoven: both can exist together- Chronologies- the sequencing of events- can be a good starting point
- Change is a process, with varying pace and patterns. Turning points are moments when the process of change shifts in direction or pace
- Progress and decline are broad evaluation of change over time. Depending on the impacts of change, progress for one people may be declined for another
- Periodization helps us organize our thinking about continuity and change. It is a process of interpretation, by which we decide which events or developments constitute a period of history
