Continuity means something stayed substantially the same across the period. Variation means that, inside that continuity, some groups or details were different. A strong answer reports both, because “how much did it change?” cannot be judged without knowing what did not.
This lesson builds on using evidence to show a documented change and prepares the ground for structuring a balanced comparison. It sits in the change, continuity and comparison module.
Why look for what stayed the same?
Change questions ask “how much?” or “how far?”. The answer sits on a scale from “hardly at all” to “completely”, and continuity is what keeps it from sliding to the extreme.
If most jobs, places and customs were the same at both dates, then calling the period “a revolution” would overstate it. Continuity is the check on your own judgement.
How to find continuity, step by step
- List the features at the start date in your chosen dimension.
- List the features at the end date.
- Mark the features that appear in both lists. These are candidates for continuity.
- Look inside each one for variation. Did every group experience it the same way? Did the details change?
- Decide the weight. Is the continuity large (most people affected) or small (a minority)?
Worked example
Harbourtown is an invented town, and the evidence below is made up for practice.
Dimension: the main ways people earned a living, 1900 to 1950.
Features in 1900: sail-powered fishing boats, a weekly fish market on Fridays, fishing as the largest employer (70% of 1,600 workers, which is 1,120).
Features in 1950: motor-powered fishing boats, the Friday fish market, fishing as the second-largest employer (40% of 3,600 workers, which is 1,440), and a cannery as the largest.
Step 3, shared features: fishing from the same harbour, and the Friday market.
Step 4, variation inside them: the boats changed from sail to motor. Fishing’s share of work fell. The market sold fresh fish in 1900 but also supplied the cannery by 1950.
Invented source D (labelled as invented), a market trader’s diary, 1949: “Fridays are the same as when my father stood here, only the lorries are new.”
This is a viewpoint. It supports continuity in the market’s day, but it also mentions a change, the lorries. The diary tells us what the trader noticed, not everything that happened.
Step 5, weight: fishing still employed 1,440 workers in 1950, more than in 1900 in number. The continuity is large.
Judgement: “Although canning changed the town’s main employer, fishing and the Friday market continued, so change in Harbourtown’s work was substantial but not complete.”
The mistake to watch for
Two opposite slips happen here.
Mistaken answer 1: “Nothing changed in Harbourtown because people still fished.”
Mistaken answer 2: “Everything changed because there was a cannery.”
The first ignores the motor boats and the falling share. The second ignores the 1,440 fishing workers and the Friday market.
The correction is to hold both: name what continued, name what varied within it, and say which is more important for the question. A sentence beginning “Although” or “However” often helps you keep both in view.
Check yourself
1. The Friday market ran in 1900 and 1950. In 1900 it sold only fresh fish; by 1950 it also supplied the cannery. Is this continuity, change or both?
Show answer
Both. The weekly market continued (continuity), while what it sold and who it supplied widened (variation or change inside it).
2. A student writes, “Fishing continued, so nothing changed.” Give one piece of evidence that shows this is too simple.
Show answer
Fishing’s share of jobs fell from 70% to 40%, and boats changed from sail to motor. These show change inside the continuity.
3. Why might a historian weigh continuity as “large” in this example?
Show answer
Because the number of fishing workers rose from 1,120 to 1,440, so fishing still affected many people in 1950.
Where this leads next
With change and continuity both in hand, you are ready to structure a balanced historical comparison. If you want to revisit dating and context first, see chronology and historical context.
Judging “how far” takes practice, since it depends on weighing evidence rather than listing it. Our teachers support that kind of reasoning in online one-to-one History tuition.
