The Autonomy Act was legislation passed by the US Congress in 2052. It devolved political powers to Mega-City One, Mega-City Two, and Texas City, allowing them virtual self-government except for foreign affairs and the military. Some Americans considered this the end of the United States as a superstate, though Governor Robert L. Booth welcomed the change.
Within three years of the Act, Mega-City One imposed immigration laws on Americans trying to enter the city.
