Through various universes, Rick has been involved through resistance groups against the Galactic Federation, as well as other groups who consider his genius a threat, such as galactic terrorists, sub-galactic dictators and most of the entire Intergalactic government. To protect themselves and hide from opposing groups, a "few thousand" alternate versions of Rick decided to join together and create their own society. It is presumed the Citadel was in a dimension specifically created by Ricks, similarly to how Evil Rick created his dimension. The Citadel is known to have existed for at least 15 years, which predates Morty's birth. At the time of its foundation it was likely solely inhabited by Ricks, who would have been in their 50s or younger, but more and more Ricks continued to join the Citadel up to recent times.
A force referred to as the "Citadel's militia" performs military and security duties for the Council of Ricks. It is headed by a commander-in-chief. The militia is comprised mostly of uniformed Ricks, but some Mortys could also be seen in their ranks. SEAL Team Ricks appear to be an elite component of the militia.
Since many Ricks are against the idea of forming a government due to his own political views, a group "anti-Rick" activists are known to exist. Such Ricks include C-137 and The Scientist Formerly Known as Rick.
Rick C-137 is taken to the Citadel under suspicions of murdering 27 Ricks, he meets with the Council of Ricks then escapes. The Citadel is shown again when the Rickless Mortys are taken in: Evil Morty blending in with the crowd. Presumably, they were all placed with the schooling programme.Council of Ricks - also Galactic Federal prisoners, officials and guards. The Citadel engages in a brief conflict with the surviving members of the Galactic Federation and Prisoners.
The Citadel is revealed to have survived the teleportation and apparently has been relocated. An effort was made by numerous Ricks and Mortys to collect donations to redevelop the Citadel, including asking Rick C-137, in spite of his role in its destruction. The station has been repaired and with the death of the Council of Ricks, has transitioned into a democratic government. An election was held, and was won by a Morty who, unbeknownst to the population, was Evil Morty.
The Citadel is located within an orange/brown nebulae, and is a massive space station with a central glass dome, with three separate, smaller domed districts protruding from it. Several metallic plates extend from the bottom, presumably housing machinery used to keep the Citadel stable and in orbit.
The interior of the Citadel has a mixture of metal structures and natural fauna, with numerous fountains, trees, and distinct curved buildings. Somewhere within the Citadel, a large statue depicting an unspecified Rick sits in a central column. The Citadel contains a mega-city within its structure, with several divisions and districts such as the Mortytown ghetto where the Creepy Morty is located. The city has its own fully-functional economy and infrastructure, consisting of Ricks and Mortys.
In the middle of the Citadel, there is teleportation room, which is capable of teleporting the whole Citadel to a chosen location. It is fueled by the same green energy within the Portal Gun of every Rick.
The Citadel disposes of its garbage via a large portal that funnels the waste to other dimensions. Many Mortys believe the false myth that this portal is actually a wishing well.
The Ricks are generally considered the upper class, as they are adults and have a higher IQ, while the Mortys form the lower class. Many Ricks harbor prejudice against the Mortys. However, some Mortys have worked their way into positions of power, such as Evil Morty being elected president. Mortys also form part of the police force and there are many Morty business owners.
Every Morty is ideally assigned a Rick, but many Mortys appear to be either Rickless or living apart from their Ricks. Mortys who have not yet gained employment instead attend school but the curriculum is little more than brainwashing and psychological conditioning and is based entirely on them learning how to be subservient to their future Ricks.
Despite the Ricks being in the upper echelon of this society, there are Ricks that work menial jobs and those who sit at the top. It was this useless and menial work that made Rick J-22 fed up with the Citadel of Ricks and demand a portal gun to be free of his "prison". Ironically, as Rick stated, this kind of social system was the very thing that Ricks despised, and by becoming a part of this, a great many of the Ricks lost whatever made them unique, which Rick J-22 noted as well.
Despite Ricks anarchic tendencies, the Citadel was (rather hypocritically) governed by a Council of Ricks, consisting of six primary members. Following the destruction of the Citadel and subsequent death of all the Council members, the government shifted to a democratic system, complete with presidential elections. However, the true power of both governments resided in a larger, more secret Council of Ricks. After exploiting the election process and murdering most of the Shadow Council (among other rivals), Evil Morty established himself as a totalitarian dictator.
