In the era of Alexander, grandson of Caesar, the Taylorites were a political movement/religious cult among the rebellious humans and the human/ape hybrid 'Mud People', with some ape followers. The revered holy book they based their beliefs on was the journal of Dr. Lewis Dixon. The information he recorded therein, the tales told to him by Zira and Cornelius about the Earth's future dominated by apes, and about the arrival of the talking human Taylor, constituted a book of prophecy to the Taylorites. They demanded equal rights for humans and apes before the promised return of Taylor and his destruction of the planet.
