Good History Thesis Statements

Needs Work: The agricultural revolution was important. Society came about because of advances in farming and irrigation. This paper will look at “Hammurabi’s Code” and other documents to get a picture of the time period. The agricultural revolution allowed cities to form, specialization to occur, and things like religion, art, language, and money to be invented. This paper will show the good and bad aspects of the agricultural revolution.

This introduction makes it clear that there is evidence being used, but it does not take a position. Because the author is just describing the good and bad aspects, the paper will probably not add to the discussion of the topic, but merely reiterate what is already known.

Better: The agricultural revolution had an irreversible effect on the social world of humans. Advances in farming and irrigation allowed cities to form, specialization to occur, and more complex forms of government, religion, economy, language, and art to flourish. While the agricultural revolution allowed society as we know it to begin, not every innovation benefited humans. As larger populations grew, people were divided into social classes. Inequality, war, disease, and exploitation began to occur on a devastating level that hadn’t been seen in the time before the revolution and therefore the revolution damaged human populations more than it helped.

This introduction informs the reader of the main topic and the significance of the discussion. More importantly, the writer takes a position and hints at the major points that will be used to back up that position. It is not necessary to mention in the introduction the documents being used unless specifically required by your instructor.

Guide to Writing Thesis Statements

Back to Helpful HandoutsoWriting Center Home Page


Your thesis statement is the central argument of your essay. It must be concise and well-written.
  • Your thesis goes in the introductory paragraph. Don't hide it; make it clearly asserted at the beginning of your paper.
  • Your thesis must make an argument. It is the road map to the argument you will subsequently develop in your paper.

The key difference between an opinion statement and thesis statement is that a thesis conveys to the reader that the claim being offered has been thoroughly explored and is defendable by evidence. It answers the "what" question (what is the argument?) and it gives the reader a clue as to the "why" question (why is this argument the most persuasive?).

Examples of good thesis statements:
  • "The ability to purchase television advertising is essential for any candidate's bid for election to the Senate because television reaches millions of people and thus has the ability to dramatically increase name recognition."
  • The organizational structure of the United Nations, namely consensus voting in the security council, makes it incapable of preventing war between major powers."


1. Thesis statements must make a claim or argument. They are not statements of fact.

Statement of fact: "A candidates ability to afford television advertising can have an impact on the outcome of Congressional elections." This is essentially an indisputable point and therefore, not a thesis statement.

Similarly, the claim "The United Nations was established to promote diplomacy between major powers." is not likely to inspire much debate.

2. Thesis statements are not merely opinion statements.

Statement of opinion:"Congressional elections are simply the result of who has the most money." This statement does make a claim, but in this format it is too much of an opinion and not enough of an argument.

Similarly, "The United Nations is incapable of preventing war" is closer to a thesis statement than the factual statement above because it raises a point that is debatable. But in this format, it doesn't offer the reader much information; it sounds like the author is simply stating a viewpoint that may or may not be substantiated by evidence.

In conclusion, your thesis should make clear what your argument is; it should also provide the reader with some indication of why your argument is persuasive.

For example: In the congressional elections example, why is money important (and whose money? The candidates'? Corporations'? Special interests'?), are other factors irrelevant (the candidates' views on the issues?) and for which types of elections is this true (is your argument equally true for Senatorial elections and elections for the House of Representatives? Why or why not?)?

In the other example, you will need to think about why the United Nations is not capable of preventing war. Your thesis should indicate that you have an understanding of the relevant historical circumstances and that you are aware of alternative explanations.

Of course, one can re-work a thesis statement indefinitely and one can almost always find something at fault with it. The point is that you must be sure that your thesis statement is indicating to your reader that you have an argument to make.
