The following questions may help to probe specific concepts:

Context & chronology	When did this happen? Where did it happen? In what order did it happen? What was the broader historical context? What were the characteristic features, conditions and outlook of the period? In what ways is the broader context significant? In what ways did the conditions and perspectives of the time trigger, shape, determine or constrain events? Did one or more elements in a sequence of events or situation combine to make another action/outcome possible/probable? How are our interpretation and explanations of context affected and shaped by hindsight?
Change and Continuity	What types and variation of change was taking place at the time? e.g. political, economic, social; cultural, religious, technological? Were there key events, turning points or individuals that triggered, precipitated or motivated change? What was the speed/ rate/ extent / impact of change? e.g. was it  rapid, gradual, erratic, violent, widespread or localised?  Did it affect certain groups / sectors of society more than others? What was the duration of change? e.g. short-lived or long-term? Did the change result in progress, regression, evolution or little real change? (continuity). How have our interpretations and explanations of continuity and change been influenced and informed by hindsight?
Cause and consequence	What variety of factors/ reasons combined to bring about change at any given time? What were the significant causes, turning points, sequence of events or developments? What combination of causes and consequences enabled or determined particular outcomes? Were some events or developments or people more important than others? What was the relative significance or importance of different factors? What were the intended and unintended short, medium and long term outcomes/ consequences? Which aspects made the most difference to the outcomes? How are our interpretation and explanations of causes and consequences influenced and informed by hindsight? How did individuals interact with the context to shape events? Which individuals were significant?  What part did they play? How did individual hopes, intentions, beliefs, motives and decisions affect their actions? How were individuals shaped by events? How are our interpretations and explanations of individual actions influenced by hindsight?
Role of individuals	How did individuals interact with the context to shape events? Which individuals were significant?  What part did they play? How did individual hopes, intentions, beliefs, motives and decisions affect their actions? How were individuals shaped by events? How are our interpretation and explanations of individual actions influenced by hindsight?
Significance	How important / remarkable was the event, issue or person at the time and/or since? How many lives were affected at the time, in the interim or since? How significant was the change at the time and since? What is the nature of the collective memory?  How relevant is the event, issue or person to people and circumstances today? How deeply / profoundly did the event, issue or person affect the context at the time? What have been the consequences?  How durable have the consequences been and why? How are the events remembered within the collective memory of a group or groups?  How and why do events then still resonate today? Why are these events so closely connected to group experiences, beliefs or situations over time? How are judgements about significance related to the value systems of the period in which they were produced? How have judgements about significance changed over time?
