What's a thesis statement, and how do I write a good one?
A thesis statement lays out your argument (tells the reader what your essay will is all about). A good thesis statement should be near or at the end of your introduction paragraph. It should be clear, and you should be able to connect every other paragraph to it.
Why was the Stamp Act of 1765 significant?
