World War V

World War V was a global conflict in the 49th century. The Doctor was present, no later than his fifth incarnation. (DW: The Unquiet Dead, BFA: Singularity)

During the conflict, much of Earth's art treasures were destroyed, though these did not include the Mona Lisa. (DWM: Art Attack)

The Fifth 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)

It was the first world war fought on Earth in over 2,400 years as World War IV took place prior to the 25th century. (CC: Frostfire)
