Thesis ideas for WWI Essay?

A thesis statement is the main point you are trying to prove in your essay. This next part may sound insulting, but it's not intended to be--stay with me, okay? Remember how in first grade we learned that every paragraph has a topic sentence and supporting details? And how in second or third grade, we learned to elaborate on our supporting details for each paragraph? Well, for your essay, each of your points that you talk about in the essay is a supporting detail and the paragraphs about each are the elaboration. The thesis is the topic sentence of the whole essay.
