Eschatology is “a branch of theology concerned with the final events in the history of the world or of humankind.” Websters goes on to add, “specifically, any of various Christian doctrines concerning the Second Coming, the resurrection of the dead, or the Last Judgment.”
Often, teachings on eschatology might be referred to as “end times doctrine”. Other, closely related, doctrines that the Bible Study Framework tackles include premillennialism and preterism (aka realized eschatology, AD70 doctrine).
Studies in eschatology and all of its related theologies commonly includes fantastical descriptions, elaborate charts, and vastly differing conclusions. This is due to the fact that, as a biblical theology, it is based largely on interpretations from the prophetic texts of the Bible (e.g. Ezekiel, Daniel, Revelation, etc.). Consequently, these texts, by their very nature of being prophetic literature, are highly symbolic and allegorical lending themselves to imaginative speculation.
