Every part of the History assessment rewards the same two habits: supporting each claim with precise evidence, and recognising that the past can be seen from more than one perspective. These skills run through Paper 1 (sources and their perspectives), Paper 2 (examples and concepts), Paper 3 (a range of perspectives on an argument) and the historical investigation. Used well, they turn accurate knowledge into argument.

Specific evidence

Evidence is what allows an examiner to believe your argument. Old examiner reports, across every paper, criticised “general assertions” that were “not well-supported”, and praised “detailed knowledge with good analysis”. The difference is usually one of precision. The table compares general statements with specific ones that make the same point.

General (weak)	Specific (strong)
The government used a lot of violence against protesters.	At Sharpeville on 21 March 1960 police killed 69 people at a protest against the pass laws, and on 8 April the government banned the ANC and the PAC.
Germany was much weaker economically than its enemies.	In 1914 the Allies had about 2.9 times the economic output of the Central Powers, by the estimates of Broadberry and Harrison.
Many Japanese Americans were put in camps.	Under Executive Order 9066 of February 1942, about 120,000 people of Japanese descent, two-thirds of them US citizens, were held in ten camps.
Women gained some rights after the revolution.	Divorce was legalised in 1914–1915 and the Law of Family Relations (1917) gave married women more control over property, but women won the national vote only in 1953.

Building an analytical paragraph

Evidence becomes argument through the way a paragraph is built. The diagram of the parts of a paragraph shows one reliable order: a point that answers the question, specific evidence, an explanation of how the evidence proves the point, the limits or complications, and a link back to the question.

Five boxes from left to right joined by arrows: point (an argument that answers the question); evidence (dates, names, numbers, sources); explanation (how the evidence proves the point); limits (what complicates it); link (how far the claim holds). — The parts of an analytical paragraph. Evidence sits in the middle, between the argument it supports and the explanation of why it matters; the last two steps turn a well-supported point into a judgement on the question.

Write an analytical paragraph for the essay question: “Terror was more important than propaganda in maintaining Stalin’s rule.” To what extent do you agree with this statement? Label each part.

Show the worked example

Point. Terror was the more important method in the late 1930s, because it removed every possible source of opposition and made obedience a matter of survival.

Evidence. During the Great Terror of 1937–1938, the NKVD’s own records show about 680,000 executions, and hundreds of thousands more people were sent to labour camps. The victims included more than half of the delegates to the Seventeenth Party Congress of 1934 and much of the senior command of the Red Army, among them Marshal Tukhachevsky, shot in June 1937.

Explanation. By destroying the party’s old leadership and the army command, the Terror eliminated the groups that could have replaced Stalin, and the arrest of ordinary workers and peasants on quotas taught the whole population that criticism, or even association with a suspect, could be fatal.

Limits. Yet terror alone cannot explain why many Soviet citizens supported Stalin. The cult of personality, socialist realist art and the celebration of heroes of labour such as Stakhanov in 1935 gave millions, especially the young and the newly promoted, reasons to believe in the regime, and terror was itself justified to the public through propaganda about spies and wreckers.

Link. Terror was therefore the more important method in removing opposition, but it worked alongside propaganda, which explained and justified it, so the statement is largely true for the elite and less true for the population as a whole.

Why it works. The point answers the question; the evidence is specific (dates, figures with their source, named victims); the explanation says how the evidence proves the point; the limits bring in the other side of the claim; and the link gives a qualified judgement on the statement.

Statistics and quotations

Numbers and short quotations are the most persuasive kinds of evidence, and the easiest to misuse. A few rules keep them accurate.

Round honestly. “About 120,000” or “more than 8,000” is better than a precise figure you are not sure of. An invented precise figure is worse than an honest approximation.
Give ranges for contested figures, and say why they differ. Estimates of deaths in the Soviet famine of 1932–1933 range from about 5.5 to 8.7 million for the USSR as a whole, because records were incomplete and historians count excess deaths differently. Showing that you know a figure is contested is itself a mark of understanding.
Attribute numbers where it matters. “The NKVD’s own records show …” or “by the estimates of Broadberry and Harrison …” tells the examiner where the figure comes from and how far to trust it.
Make numbers comparative. A number means more beside another: Allied and Central Powers output, US and Japanese aircraft production, African seats and European seats in Kenya’s Legislative Council.
Keep quotations short and integrated. A phrase of a few words, built into your own sentence, shows knowledge and saves time: the Atlantic Charter promised “the right of all peoples to choose the form of government under which they will live”. Never quote words you are not sure of; paraphrase instead.

Four kinds of perspective

The word perspective appears in every part of the assessment, with slightly different emphases. In Paper 1 it means the viewpoints of the sources; in Paper 2 Section A it is one of the four concepts; in Paper 3 it means the range of angles from which the argument in the question can be evaluated; in the IA it is part of the analysis of sources. All four uses share one idea: what people see in the past depends on where they stand.

Kind of perspective	What it is	Example
Groups at the time	How people in different positions experienced or understood an event	For the party leadership, collectivisation was the route to industrial growth; for peasants it meant the loss of land, deportation and famine
Sources	The viewpoint a source expresses or represents, shaped by its author, purpose and audience	The MK manifesto of 1961 presents armed struggle as forced on the ANC; government statements presented it as communist terrorism
Historians	Interpretations of the past, shaped by evidence, approach and the time of writing	Fritz Fischer (1961) places responsibility for 1914 on Germany; Christopher Clark (2012) spreads it across every capital
Angles on a question	Different factors, areas of life, regions or phases from which a claim can be tested	Testing “the war caused the movement” from political, economic and social angles, or for urban and rural people

Using historians well

A historian’s interpretation is useful in an essay when it does work: when it sharpens an argument, offers a view to test, or explains why a question is debated. To use one well you need four things: the historian’s name, their work and its date if possible, their argument in one sentence, and the evidence they stress. With those, you can say why their view is convincing or limited for the question you are answering.

Weak use	Strong use
Fischer said Germany caused the war, but Clark disagrees.	Fritz Fischer, drawing on German government archives in Griff nach der Weltmacht (1961), argued that Germany’s leaders encouraged Austria-Hungary in July 1914 because they accepted a general war as the price of expansion. This supports the claim that the decisions in Berlin were decisive. Christopher Clark’s The Sleepwalkers (2012) qualifies it: by examining Belgrade and St Petersburg as closely as Berlin, Clark shows that leaders in every capital made choices that brought war closer, which suggests that the question “who caused the war?” is less useful than “how did a Balkan crisis become a general war?”.

Debates are often described in terms of schools. An orthodox interpretation is the first widely accepted account, often close to the view of the victors or the government of the time; revisionism challenges it, often with new evidence or a new approach; post-revisionism tries to combine the strongest parts of both. The origins of the Cold War are a standard example: an orthodox view in the West blamed Soviet expansion; revisionists from the 1960s, such as William Appleman Williams, stressed American economic interests; post-revisionists such as John Lewis Gaddis in the 1970s spread responsibility between the two powers. Use these labels only when you can say what each school argued.

Why historians disagree

Explaining why interpretations differ is a stronger move than simply reporting that they do, because it lets you judge between them. Most disagreements come from four sources.

Reason	What it means	Example
Evidence	New archives or sources change what can be known	Soviet documents released in the 1990s showed that Stalin approved Kim Il Sung’s attack in spring 1950, weakening interpretations that saw the Korean War mainly as a response to the South or to the United States
Time of writing	Historians write in and for their own present	Fischer’s argument shocked West Germany in the 1960s because it suggested continuity between the aims of 1914 and those of the Nazi era
Approach or ideology	Marxist, liberal, social, cultural and other approaches look for different causes	Marxist historians explained the French Revolution as a bourgeois revolution; revisionists stressed political and financial crisis
The question asked	Historians asking different questions reach different answers from the same evidence	Clark asks how the war came about, not who was guilty, so his answer spreads responsibility more widely

An essay asks: To what extent do you agree with the perspective that Stalin intended the famine of 1932–1933 in Ukraine? Show how to weigh two historians’ interpretations.

Show the worked example

Step 1: state each interpretation precisely. Robert Conquest, in The Harvest of Sorrow (1986), and Anne Applebaum, in Red Famine (2017), argue that Stalin used the famine to break Ukrainian peasant resistance and national feeling. R. W. Davies and Stephen Wheatcroft, in The Years of Hunger (2004), accept that Stalin’s policies caused the famine and that he refused relief, but argue that the evidence does not show an intention to destroy Ukrainians as a nation.

Step 2: identify what they agree on. Both accept that the regime’s procurement policies caused millions of deaths and that relief was withheld. The disagreement is narrower than it first appears: it is about intent.

Step 3: explain why they differ. Conquest wrote during the Cold War with limited access to Soviet archives; Applebaum and Davies and Wheatcroft used the archives opened after 1991 but read them differently. Applebaum stresses measures aimed at Ukraine in particular, such as the blacklisting of villages and the ban on peasants leaving the republic in January 1933; Davies and Wheatcroft stress the famine across the USSR, including Kazakhstan, and argue that the leadership misjudged the harvest.

Step 4: weigh them against the question. Measures targeted at Ukraine support the perspective that Stalin intended the famine to fall hardest there; the famine’s spread to other regions and the absence of a documented order to cause it support the view that it was the result of ruthless policy rather than a plan. A judgement might be that Stalin knowingly used the famine against Ukrainian resistance once it had begun, which supports the perspective in part, while the evidence for an original plan to cause it is weaker.

Why it works. The historians are used to test the claim, not to decorate it; their agreement and disagreement are both identified; their differences are explained by evidence and approach; and the judgement says how far each supports the perspective in the question. The subject is treated with care, and the contested view is attributed to those who hold it.

Silences and marginalised voices

A perspective can be missing as well as present. The written record over-represents those who could write and whose papers were kept: governments, elites, men, colonisers. The experiences of enslaved people, peasants, women, colonised peoples and minorities often survive only in other people’s records, in oral testimony or in the traces of what they did. Noticing who is missing, and asking how their absence affects an argument, is a sophisticated use of perspectives in every paper.

Nottingham Trent University, “How to Write a history essay: Advice and Tips”: university historians on argument, evidence and structure. Not written for the IB, but its advice on supporting every claim with evidence applies to every paper.

Common mistakes

General assertions. Claims without dates, names or numbers. Every paragraph should contain at least two pieces of specific evidence.
Evidence without explanation. Facts listed but not linked to the argument.
Name-dropping. Historians mentioned without their argument, or with an argument attributed to them that they do not hold. If unsure, describe the interpretation without a name.
Presenting a contested figure or view as settled. Give ranges, and attribute contested interpretations.
Treating perspectives as bias to be dismissed. A one-sided source is still evidence, above all of its author’s view. Ask what it can show, not only what is wrong with it.

TED-Ed, “Debunking the myth of the Lost Cause: A lie embedded in American history” (Karen L. Cox): the Lost Cause interpretation of the US Civil War and how historians have assessed it. It illustrates how an interpretation reflects its authors’ purpose and time.
