The original Caesar, played by Roddy McDowall in Conquest and Battle, was the son of Zira and Cornelius. He was born Milo at Armando's circus in 1973. Raised by Armando at the circus, he was unaware of the devastating plague that wiped out the Earth's cats and dogs until Armando finally brought him to California in 1991. The resulting events of Armando's arrest and subsequent death, and the realization that his fellow apes had been reduced to slavery, spurred Caesar to instigate the revolt that resulted in the ascendancy of the apes. Following the nuclear war that followed the revolution Caesar led his people far away from the cities where they lived an idyllic life until their presence was discovered by the mutated humans who lived in the Forbidden City.
