No Man's Land is a period in Gotham City when, after suffering the results of a magnitude 7.6 earthquake and two separate plague outbreaks, the U.S government declared Gotham not worth rebuilding and estranges the city from the rest of the country; destroying all bridges and arteries and forbiding people from entering or exiting the city.
With the national guard forming a barrackade around city limits, the Justice League of America were forbidden by law from entering the city. The situation was left to Batman and his associates to find a way to rebuild the city as the streets fell into ganglands and tribal territory.
Money became worthless; people instead would barter anything from batteries to services to protection for daily necessities. Graffiti tags were used to mark various territories between gangs and warlords.
It wasn't until Lex Luthor, intent on rebuilding and owning the city much like he did Metropolis, entered the city and forced public opinion against the US government's decision to estrange the city.
