Laterano is a parallel to the Papal States, noted by its religious influence. The name derives from the Lateran Palace, the main residence for the Pope.
The name itself also likely refers to the Lateran Treaty (Pacta Lateranensia) that led to the creation of the modern Vatican City, the successor of the Papal States, in 1972.
Many Lateran pagi and avenues are named after Catholic saints and Apostles in the Bible such as Stephen and Saint Servatius.
Ambrosio Monastery might be named after Saint Ambrose.
Elements of Switzerland are also found in Laterano such as its political neutrality, its non-restrictive gun-laws, and its dessert culture.
The Pontifica Cohors Lateran is a direct reference to the Swiss Guards, named Pontifica Cohors Helvetica in Latin.
The Summit of Nations and the institution of the Legeti are akin to the formation of the United Nations. One of its city, Geneva, is also the second headquarters for the U.N.
The world-wide gun-control/enforcement of gun-laws through Laterano is a parallel to the Geneva Conventions.
Landen Monastery's practice of selling their own homemade bread and beer mirrors those of actual monasteries in Europe. Many of said monasteries produce and sell their own alcoholic beverages especially wines and baked goods.
The expansion of Landen Monastery in educational aspect outside Laterano also mirrors Catholic religious orders expansion outside Vatican and Italy. These religious orders often build schools or at the very least participate in educational activities such as being school teachers or university professors.
The Pathfinders' mission to break Laterano's old tradition and restrictive laws is likely a reference of Martin Luther's breaking off from the Catholics and setting up the Protestant church.
The date when the Lateran Declaration is published (March 18) is when the teaser trailer of Arknights: Endfield is released.
