An argument is a set of propositions designed to demonstrate that a particular conclusion, called the thesis, is true. An argument is not simply a statement of opinion, but an attempt to give reasons for holding certain opinions. An historical argument gives reasons for holding a certain opinion about an event in the past.
An historical argument should include the following elements: 1. Thesis Statement; 2. The Argument; 3. The Evidence. The historical argument should always be evaluated to assure that the argument is persuasive, the reasons for the argument are plausible, and there is sufficient evidence to support the argument. It is important that the historical argument take into account counter examples for the sake of objectivity.
