A chronology is a dated sequence of events that you can reason with. In a Russia depth study it appears whenever a question gives a date range, asks what came before or after something, or needs you to decide whether one development could have caused another.
It sits at the base of the Russia depth-study pathway and builds on chronology and historical context.
What makes a chronology useful rather than just a list?
A list of dates is memory. A chronology is structure: each entry has a precise date or range, a label for what kind of thing it is, and a place within a phase.
Use three tools.
- Points and spans. A signing or a death is a point. A civil war or an economic programme is a span with a start and an end.
- Phases. Group entries into periods that your syllabus or teacher treats as a unit, for example the year of the two 1917 changes of government, a war, a period of recovery.
- Arrows. Between entries, mark where one development plausibly led to another. An arrow is a claim, so be ready to support it.
Watch the calendar
Until early 1918 Russia used the Julian calendar. In the twentieth century it ran thirteen days behind the Gregorian calendar. Russia changed in early 1918, so 31 January became 14 February.
This is why the Bolshevik seizure of power is traditionally called the “October Revolution” in the Julian calendar, while the same day falls in November in the Gregorian calendar. Neither label is an error. Use the convention in your course and say which you use.
Worked example
Question: Put these events in order and group them into phases.
- Treaty of Brest-Litovsk signed (March 1918)
- Tsar Nicholas II abdicates (March 1917, Gregorian dating)
- New Economic Policy introduced (1921)
- Civil war (1918 to 1921)
- Bolshevik seizure of power (7 November 1917, Gregorian; 25 October in the Julian calendar)
Step 1, separate points from spans. The civil war is a span. The other four are points.
Step 2, sort by date. Abdication (March 1917), seizure of power (November 1917), Brest-Litovsk (March 1918), civil war (begins 1918, ends 1921), NEP (1921).
Step 3, phase. Change of government in 1917: abdication and seizure of power. Ending one war and fighting another: Brest-Litovsk and the civil war. Change of policy as the fighting ended: the NEP.
Step 4, add one arrow. Brest-Litovsk took Russia out of the First World War, but the civil war that followed meant the country did not move to peace. Write the arrow as a claim and note the evidence you would use.
Final chronology: March 1917, November 1917, March 1918, 1918 to 1921 (span), 1921.
The mistake to watch for
A common slip is to order by “which one I learned first” or to put the civil war at a single year.
Mistaken answer: “Civil war 1918, Brest-Litovsk 1919, NEP 1921.”
The student treated the civil war as a point and misdated the treaty, so the cause-and-effect order is wrong.
Correction: ask two questions for every entry. Is it a point or a span? What is the safest anchor for its date?
Check your textbook for the exact start and end of any span.
Check yourself
1. Put in order: NEP introduced (1921), abdication of Tsar Nicholas II (March 1917), Brest-Litovsk (March 1918).
Show answer
Abdication (March 1917), Brest-Litovsk (March 1918), NEP (1921).
2. A source says the Bolsheviks took power “on 25 October”. Another says “7 November”. Can both be right?
Show answer
Yes. They describe the same day using the Julian and Gregorian calendars, thirteen days apart. The only error would be to treat them as two events.
3. Should the civil war be drawn as a point or a span, and why?
Show answer
A span, because it lasted for years, from 1918 to 1921 in the standard outline. A point would hide that other events happened during it.

With the order secure, you can ask what a source says about it in Interpret a source in its documented setting. Test the whole pathway later in the integrated practice set.
