After the end of the Population War, the victorious Human League did not simply dissolve. The Population War had been the most traumatizing experience of the modern era, easily eclipsing the Global War, Liberal War, and Napoleonic Wars. The Great Powers of the Human League did not want to see another extremist movement plunge the world into flames the way Korsgaardism and Malthusianism had in the previous conflicts. Also, many of the leaders of the Human League were proud of the Human League Declaration of Rights and saw value in seeing it upheld on the international stage. While the original membership of the Human League was the military alliance forged in opposition to Malthusian Mania, other nations quickly petitioned to join the League's efforts, such as redeemed France and Mexico. However, the Human League was also petitioned by break away nations such as Moskito and Cygne Noir. An early rule for joining the League was settling all border disputes prior to joining. The League Powers offered mediation services to settle disputes in aid of joining the League, giving birth to the Human League Agency for International Mediation (AIM).
A parallel development with the rise of the Human League was the Movement for International Peace. The movement was started by nations that had experienced excessive amounts of fighting within their borders over the past century, such as Mexico, Brazil, Germany, Austro-Bohemia, Hungary, and the Ottoman Empire. This popular movement called upon world leaders to find new ways to resolve disputes and to prevent future wars. The Movement for International Peace was joined by another popular movement, the Wounded Against War Inhumanity, which started with Population War survivors of Malthusian massacres and chemical warfare who sought to ban inhumane and indiscriminate violence in warfare (well in keeping with the Declaration of Human Rights). These peoples' movements would over the next few years have a profound impact on the popular imagination and on world leaders, leading to the Human League ban on developing, stockpiling, and especially use of chemical weapons and any agent of similar horrific or indiscriminate effect such as theorized biological or uraniumic (or other heavy elatomic) weapons. It would also spur the decades long process of military de-escalation and the rise of the Human League's Pax Legion.
The victors of the Population War were an odd combination of traditional Liberal nations and former Korsgaardian nations as well as some nations who had little in the way of major ideological underpinnings. Russia was in some ways the most resistant to any international disarmament movement. While Russia had sent massive troop numbers into the wars of the 19th and 20th centuries, the Rodina had been largely spared invasion for the most part and it was popularly perceived that Russian military might had been the shield of the nation (as well as the several somewhat friendly buffer states that Russia had managed to cultivate on its borders over the years). However, Russian intellectuals and the Tsar were anxious to be seen by the world as a more liberal, cultured nation than it had in the past so eventually was able to come to an agreement that ensured retention of enough military forces to defend Russia's borders (and indeed this was a concern of many of the victors given their experience of the aggression of the Malthusians).
Some defeated nations after the extremism of Malthusians had lost all taste for war, such as the Netherlands and Belgique. They passed new constitutions that forever foreswore war and replaced their military with a national police force. They asked the Human League to guarantee their borders and safety in return for their institutionalized pacifism, and this would be another role for the Pax Legion.

It was recognized within a couple years that the movements towards de-escalation and disarmament as well as some nations' desire to eschew militarism entirely would require an international force to enforce the peace, giving birth to the Human League's Pax Legion. The initial leadership of the Pax Legion was drawn from the Great Powers who had won the Population War for the Human League. However, when it came to designating which national would be the commander of the Legion forces, it was clear that old rivalries between the European Powers of the East and West would preclude those nations initially. However an obvious choice emerged from the relatively pacifistic but powerful nation of the United States of America. Thus it was not surprising that the Pax Legion was structured somewhat along the lines of the Legion of America. However, several renowned national forces would eventually be seconded to the Pax Legion and influence their culture and history, including the Russian Cossacks, Durrani Warriors, Sikhs, Gurkhas, the Samurai Brigade, the Black Watch, the Sable Legion, and countless other elite troops who would find a home for their martial traditions in an international force dedicated to defending the peace. The Pax Legion troops initially carried the weapons provided by their home nations, but a transitional period would see them equipped with the arms being shed by national forces as part of the disarmament process (especially motorised transport, ships and air vehicles), but eventually the Pax Legion would lead the world in the development of less lethal armaments in an ever increasing effort to pacify without destroying. Indeed, the Pax Legion eventually became heavily influenced via some of its United States of China cadre by the works of Sun Tzu and ever sought ways to enforce the peace before war ever need be initiated.
