 An automated economy has created massive unemployment, which gives rise to an antitechnology movement called Humanism (a term having little to do with the historical philosophy of Humanism, and is indeed in many ways antithetical to it).Around 2170, the Humanists seize control of Earth, withdraw from the Solar Union, and abolish the Psychotechnic Institute.The Humanist regime quickly grows unpopular, and is overthrown by a popular uprising aided by Mars and Venus.
