World War V

World War V was a global conflict in the 49th century at which the Doctor was present, either during or prior to his fifth incarnation. (DW: The Unquiet Dead, BFA: Singularity) In it, much of Earth's art treasures were destroyed, though that did not include the Mona Lisa. (DWM: Art Attack) The Doctor once rebuked Qel for the failure of the Somnus Foundation's museum of future history to even mention the conflict in its entry on the 49th century. (BFA: Singularity)
