To build a dated sequence, list each event a source describes, give it a date or a date range, and then order those events. The key move is to separate when the event happened from when the source was written. This appears whenever a History question hands you several extracts and asks what happened and in what order.
The skill sits in chronology and historical context and supports every later cluster of History.
How do you build the sequence step by step?
- Read each source for events, not for its opinion yet. Underline every event it mentions.
- Record two dates for each source: the document date and the event date. If a source gives only one, write “not stated”.
- Look for time clues such as “last October”, “the following spring”, “three weeks later”.
- Place the events in order and mark each as dated, approximate or relative only.
- Note the evidence next to each entry, for example “Source A, line 2”.
Worked example
All of this is invented practice material about the imaginary harbour town of Port Selan. It is not real history.
Source A (invented council minute, 12 May 1902): “The council votes to build a seawall. The storm of last October showed the warehouses cannot be left exposed.”
Source B (invented newspaper report, 20 October 1901): “A storm struck the harbour overnight. Water entered the warehouses on the east quay.”
Source C (invented merchant’s letter, 2 January 1903): “The builder signed the seawall contract on 22 December. Work starts in the spring.”
Source D (invented harbour ledger entry, 15 August 1903): “The seawall is complete. The first ship tied up beside it today.”
Step 1 and 2, events and two dates.
| Source | Document date | Event described | Event date |
|---|---|---|---|
| A | 12 May 1902 | Council votes for the wall; refers to a storm | Vote: 12 May 1902. Storm: “last October” |
| B | 20 October 1901 | Storm floods warehouses | Overnight, about 19-20 October 1901 |
| C | 2 January 1903 | Contract signed; work to start | Signed: 22 December (year not stated) |
| D | 15 August 1903 | Wall complete; first ship docks | 15 August 1903 |
Step 3, time clues. Source A says “last October”. Because the minute is from May 1902, “last October” must mean October 1901. Source C gives no year for 22 December, but a letter written on 2 January 1903 refers to the December just ended, so it is December 1902.
Step 4, the sequence.
- About 19-20 October 1901: storm floods the east quay warehouses (Source B, confirmed by A).
- 12 May 1902: council votes to build a seawall (Source A).
- 22 December 1902: contract signed (Source C).
- Spring 1903: work to start (Source C, relative only, a plan and not a recorded event).
- 15 August 1903: wall complete, first ship docks (Source D).
Entry 4 is marked as relative only because the source says work “starts” in spring, which is an intention, not a recorded event.
What mistake do students make?
Mistaken sequence: 12 May 1902 vote, then 20 October 1901 storm, then 2 January 1903 contract…
The student used the document dates. That puts the vote before the storm, which contradicts Source A itself. The correction is to ask of each source, “what is it describing, and when did that happen?” The document date is useful later, when you judge how close the writer was to the event.
Check yourself
1. Source E (invented diary, 9 March 1904) says: “The ferry to the north bank stopped running last week.” Give the document date and the most precise event date.
Show answer
Document date: 9 March 1904. Event date: the week before, roughly 1-8 March 1904. It is approximate, so write it as “early March 1904” and not as a single day.
2. Using Sources A to D above, how long passed between the council vote and the completed wall? Give the answer in months.
Show answer
From 12 May 1902 to 12 May 1903 is 12 months. From 12 May to 15 August 1903 is 3 months and 3 days. The total is about 15 months.
3. Why should the plan to start work “in the spring” be marked differently from the contract signing?
Show answer
Signing is a recorded event with a date. “Work starts in the spring” is a plan stated in a letter. The sequence should show that it is an intention, because the letter does not prove the work began then.
Where this leads next
Once the order is secure, the next question is why events followed one another. Distinguishing a sequence from a causal explanation takes that step. When you want to test the whole module, use the integrated practice set.
