Age of Universal Peace

The Age of Universal Peace started at the beginning of the year 2409. It came following the Dalek invasion of Earth's solar system in 2400. (PROSE: Break-through!)

Historical discrepancies with the Dalek Wars

Accounts of the Age of Universal Peace lasting "two hundred years" until the beginning of the invasion of the 27th century, (COMIC: The Mechanical Planet) conflicted with accounts of the Dalek Wars, specifically the Second Dalek War which was fought throughout much of the 26th century. (TV: Frontier in Space, PROSE: Love and War, Prisoner of the Daleks, et al.)

The narrator of The Dalek Conquests noted that writing a precise chronological account of Dalek history was made very difficult by the fact that the Daleks possessed time travel. The exact details of the effects this may have had on Dalek history and the aftermath of the 25th century invasion in particular is unclear. (AUDIO: The Dalek Conquests)
