A form of historical speculation known commonly as counterfactual history has also been adopted by some historians as a means of assessing and exploring the possible outcomes if certain events had not occurred or had occurred in a different way. This is somewhat similar to the alternate history genre in fiction. Lists of false or dubious historical resources and historical myths that were once popular and widespread, or have become so, have also been prepared. classifications Classifications History
