Those who believe that all of the prophecies of the book of Revelation were fulfilled in the first century (including the second advent, the resurrection and judgement of the dead, and the inaugeration of the eternal state) are called hyper-preterists, although adherents prefer to label their position "consistent" or "pure" preterism.
This is to distinguish their position from mainstream preterism (the prevailing opinion of postmillennialists, and also common among amillennialists and those in the Reformed tradition), which holds that many (but not all) of the prophecies were fulfilled in the first century through the destruction of Jerusalem, the reign of Nero (the beast), etc, but that some prophetic events (including the final judgement) have not yet come to pass.
