Truth (The Lie of the Land)
From Tardis Wiki, the free Doctor Who reference
During the Monks six month occupation of Earth in the late 2010s, the "True History" was a propaganda message presented by the Twelfth Doctor, which told the Monks' altered version of human history. Among other influences, the Monks took credit for saving Earth from the Daleks, the Cybermen, and the Weeping Angels. However, the Doctor was merely acting as such to gain the Monks' trust so he could overthrow them. (TV: The Lie of the Land)
