The concept of Arkham City was established long before the Joker's takeover of Arkham Asylum, conceived by Professor Hugo Strange and his secret master, Ra's al Ghul, and expanded on by Warden and later Mayor Quincy Sharp, the Joker's riot served as the lynchpin that the trio needed to enact the scheme. Arkham City was shut down after Strange and Ra's deaths.
Arkham Asylum was heavily damaged during the Joker's takeover, and many of its deranged inmates remained on the loose after his defeat, including Bane, Calendar Man, Scarecrow, Killer Croc, Mr. Freeze, and Two-Face. The asylum also suffered in losses among Arkham staff. At least 113 personnel died during the Joker's takeover, 103 of which were security guards.
Identified casualties included guard Thomas Armbruster and chief member of security Frank Boles. Aaron Cash, Louie Green, Eddie Burlow, William North, and Zach Franklin made up much of the surviving members of security. At least 10 medical staff also fell during the chaos, including doctor Penelope Young and orderly Robert Stirling.
Despite presiding over the disaster of the Asylum, Warden Quincy Sharp launched a successful bid for the role of Mayor of Gotham City following the first game. He proposed to the city government to rebuild Arkham, not on the island, but in the city itself. The proposal was approved and Dr. Hugo Strange, a top psychiatrist, was selected to administrate the new Arkham. Due to the damage to the island, it was decided that the city would sell the rights to Arkham Island to the highest bidder. TYGER, a private security company quickly purchased the island and, soon after, was named as the primary contractors for security in Arkham City.
Numerous people were involved in the new Asylum's creation, but by the time it was finished, most if not all of those involved were captured by Strange and imprisoned within the city walls as "loose ends."
As the new Asylum opened, Sharp, paranoid to end crime in Gotham, labelled everyone and anyone who even had the slightest criminal record to be inmates of Arkham City and had them imprisoned without trial or the right to objections. Strange furthered that by imprisoning anyone trying to investigate or speak out against the Asylum.
Commissioner James Gordon, suspicious of Hugo Strange's intentions and unaware of the abduction of political prisoners, sent in a ten-man squad of undercover cops from the 13th precinct to investigate what was really going on in Arkham City. Unfortunately, in an interview, Strange tipped the Penguin off to the undercover cops. They weren't able to report back before their true status as cops was exposed, and resulted in their capture by the Penguin's gang.
After he believed that the new asylum was a ticking time bomb, Bruce Wayne began making public moves against the asylum's existence, which resulted in his own incarceration into Arkham City. From within the asylum, as Batman, Bruce discovered the political climate within the city as well as the political prisoners and Strange's secret alliance with Ra's al Ghul.
During Wayne's movements inside the city, Strange decided that Quincy Sharp had outlived his usefulness, had him stripped of his position as mayor, had him incarcerated into Arkham City, and personally used the intentionally corralled chaos within the asylum to convince the Gotham City Council Members to enact Protocol 10: the destruction of the asylum and deaths of all the prisoners within.
As Protocol 10 was enacted, Batman confronted Strange personally and Ra's killed Strange for being defeated by Bruce. The chaos within the asylum was finally quelled when the Joker and Batman confronted each other within the asylum one final time, which resulted in the Joker's death and the asylum's condemnation.
With the decree that the entire asylum site to be shut down as soon as possible, as a result, Sharp's martial law was overturned and Gordon and the Gotham City Police Department were given back full jurisdiction in Gotham City. They were sent to arrest all TYGER forces, transferred all of the inmates away from the prison, rescued all the falsely imprisoned, and shut down the site once and for all.
However, Harley and Joker's remaining gang attacked the officers and forced them to retreat, but the GCPD managed to knock out Quinn and took her to the ward. For the next two weeks, SWAT forces evacuated the megaprison, however, Harley soon escaped and took over the Industrial District. As that was one of the last areas that was needed to be evacuated, the GCPD were forced to keep the site under lockdown and eventually summoned Batman. Quinn took various police officers hostage, Batman was lured into a trap by Harley, and subsequently went missing for two days. Worried, Oracle sent Robin in to investigate and locate Batman before Quinn could put her plans to kill Batman, Robin, and herself as vengeance for Joker's death into effect.
After the death of the Joker, the GCPD stormed the prison and arrested most of the villains: Victor Zsasz, Two-Face, Mad Hatter, Deadshot, Bane, Mr. Freeze, Black Mask, Penguin, Riddler, Harley Quinn, and Poison Ivy. There were some villains that they didn't find: Hush, and Calendar Man. They also could not find Ra's or Talia al Ghul's bodies. Later on, Bruce Wayne decided to make Gotham Reborn to reintegrate Arkham City back into Gotham City.
Unfortunately, as Hugo Strange had wrongfully imprisoned so many innocents and even those who had paid their debt to society, every last inmate was released. Commissioner Gordon was less than pleased, having to put up with parole hearings that were for formality's sake; Riddler was amused by this. Batman later dropped off tons of evidence from Arkham City at GCPD, belonging to Joker, Killer Croc, Mr. Freeze, Mad Hatter, Bane, Ra's al Ghul and Deadhsot. He even donated his R.E.C. to the evidence room as he had no use for it.

Arkham City was actually a large part of the already built Gotham City that was turned into a lawless war zone for the criminals of Arkham Asylum and Blackgate Prison to run free and do whatever they pleased as long as they did not try to escape. The city was surrounded by high, impenetrable walls which could only be accessed via the various high security doors around the facility and presumably via the helicopters that patrolled the city around the clock. TYGER patrolled the walls, doors, and skies via the helicopters, and kept all of the possessions of the inmates in a large vault in the western part of the city which Catwoman tried to break into at one point.
The atmosphere in the city was hell, with most inmates being violent and involved in the mass gang war between Batman's greatest enemies. The Political Prisoners hid and scurried around the backstreets of the city, and a small community had been established in the middle of the city under a bridge. Despite the lack of general rules, the inmates were under the thumb of Strange who had propaganda posters everywhere, and often issued commands and new authoritarian rules via the citywide intercom that originated from Wonder Tower, the tallest building in the city which the inmates could not access.
Numerous buildings in Gotham were part of Arkham City regardless of their previous importance in the city. Among them were the First National Bank of Gotham City, the old GCPD Building, Ace Chemicals, the Solomon Wayne Courthouse, the Church and Medical Center, a large section of Gotham's docks, and the Industrial District. Most of those buildings played a role in the game's main story and Gotham's Most Wanted Side Missions.
Most of Batman's notable villains made their mark in the city, formed territories in their gang war against one another, and had numerous henchmen who wore masks or clothes that were related to their leader(s).
Joker and Harley Quinn took over the abandoned Steel Mill in the south-east corner of Arkham, the Industrial District, and converted it into The Joker's Funhouse. The Joker developed a violent roller coaster ride for new recruits to try out on, and also built a Ferris Wheel on the site too.
Two-Face, who was growing in power, took the Solomon Wayne Courthouse as his base, after he stole it from Calendar Man and imprisoned him in his cell below the courtroom. In the style of Two-Face, half of the courthouse, inside and out, was damaged and scarred like his face.
Penguin, who was the third member of the major gang war, commanded his henchmen from The Cyrus Pinkney Institute for Natural History, as well as the Iceberg Lounge. He had his own makeshift museum which displayed numerous objects related to his enemies including the captured Mr. Freeze. He also had a giant shark named Tiny living in the flooded atrium of the museum, and Solomon Grundy beneath the Iceberg Lounge.
Riddler did not participate in the gang war, and had no real control over the city, but he built five death traps to challenge Batman after he kidnapped Cash and the medical team. The Riddler also had numerous Thugs that were hidden around the city, and were identified by Batman as having a green tint to their clothes. Riddler also has his lair in the Bowery.
Among the other inmates were Mr. Freeze who operated in the old GCPD Building, Poison Ivy who operated from Gotham's park and occupied a lair in the north-east part of the city with her hypnotized thugs, Victor Zsasz hid out in a abandoned building near the Joker's lair and kidnapped victims to kill them, Killer Croc lurked in the city's sewers and the abandoned Subway tunnels, Bane appeared in the Krank co. Toys building, the Mad Hatter's small, mind-controlled group lived in a tea shop like lair, and Hush's Hideout was found near the courthouse. While using the confusion of the prison to her advantage, Catwoman occupied an apartment in the same building as Hush's apartment.

° Batman starts investigating Deadshot's victims, finds out what happened at the old GCPD building, and goes after Penguin. Penguin blows up the central part of the Old Gotham Freeway and cuts the city in two. Many of Penguin's and Joker' Henchmen are killed, and even more are cut off on the wrong side.

° Catwoman defeats Two-Face, who had set himself up in the Museum, and most of his men with him. Batman defeats Zsasz, frees his hostages, and goes after Riddler, whom he defeats and frees his hostages. Arkham City is now divided : The Bowery, the Museum, Park Row, and few other buildings except for the Cathedral and the Iceberg Lounge (where two security teams are fortified) are ruled by Two-Face, who goes missing leading to parts of his area being overrun by thugs with no loyalty. The second part - the Joker's Funland - is now controlled by Harley Quinn. Amusement Mile is no man's land, deserted and destroyed.

° Harley Quinn captures several police officers clearing up the prison on Commissioner Gordon's command and even managed to kidnap the Caped Crusader, but is also ultimately defeated by Robin and the Steel Mill is blown up, which ends the Arkham City Civil War for good.
- During Batman: Arkham Asylum, the player could find a hidden room in Sharp's office, which revealed a large blueprint map of the project. The secret room might not be present on unpatched versions of the game, however.
- The Easter Egg was so well hidden, that the developers had to leak it out themselves a year after release.
- To uncover the hidden room, place three charges of Explosive Gel on the wall opposite of the Scarface puppet in the display case, but at the bottom of the stairs.
- The Gotham Sirens appear to be the only female inmates.
- It was revealed that Strange had intended to open new prison camps in Keystone City and Metropolis, and that they were going to modeled after Arkham City.
- The Inmates were sometimes heard complaining about it being cold even when they were inside; given this mostly happened in the Joker's territory, it's because the thugs wear tank tops.
- Some of the posters in the prison said: "An institute for the criminally insane", despite the fact that all criminals, insane or not, were sent there. It was probably because Arkham Asylum actually was an institute for the criminally insane.
- There was a minor reference to Arkham City in the video game, Lego Batman 2: DC Superheroes, where Vicki Vale mentioned the mayor's plans to build a walled off part of the city where the super-criminals could run free, and was put on hold.
- Arkham City was seen from Gotham City during Arkham Knight, and appeared to be nearly identical to its appearance during Arkham City and no clean up appeared to have started yet. However, there were also major differences, as the island was turned around 90 degrees, meaning that the Steel Mill was on the opposite side of the island to the bridge, and that there was a wall between the Courthouse and the Museum, which wasn't the case in Arkham City.
- The prison was opened at least three months before the event's of the game, as some of the Political Prisoners mentioned how they hadn't had a warm meal in three months.
- Hugo Strange made it no secret to the inmates that he called little for them, willing to let them kill each other to save himself the trouble of Protocol 10.
- All the death and destruction caused by the inmates bears similarity to The Purge film series, where all crime is legal for one night a year.
