Post-León Monarchy states
The post-León Monarchy states, also referred to as the former León Monarchy (FLM), are independent states that emerged following the collapse of the León Monarchy during the First Great War. Currently 20 internationally recognized countries exist in the area, but borders have shifted drastically over the course of the Great Wars. The Former León Monarchy itself is divided in two areas, the five countries Middle Mavona which lie in the León Monarchy's eastern kingdoms and formerly Middle Mavona, and the 15 countries of Lower Mavona which lie on the Holy Mavonan Empire and formerly Lower Mavona.
The slow collapse of the Mavonan Empire, culminating in its split in 402 and the fall of Middle Mavona in 483, completely fractured the once stable region. The Holy Mavonan Empire slowly took over Lower Mavona, Christian kingdoms in Middle Mavona fought the Middle Mavonan Crusade until eight Christian kingdoms remained by the 13th century. These kingdoms slowly united under branches of the León Dynasty, forming the Eastern Union, which united with the Holy Mavonan Empire in 1749. The turn of the 18th century and the 19th century saw and increasing number of liberal and separatist revolutions which challenged León Dynasty rule. In 1912, the assassination of Peter VIII left no clear heir, and the succession was contested by the House of Khakmadoy and House of Santa Bárbara. The crisis directly led to the start of the First Great War.
A combination of financial problems, separatist rebellions, and Furbish liberalism led to the León Monarchy being dissolved at the Boston Peace Conference. The eight eastern kingdoms, twelve root duchies of the Holy Mavonan Empire, and patriarchates of Mavona and Portobuffolé became separate countries. Peace between them was short lived, in part because borders were based on kingdom borders which did not always reflect where populations were. The Early Post-León Monarchy wars lasted from the end of the war to the beginning of the Second Great War, and several foreign interventions were not able to keep the peace in the area.
During the Second Great War, Yedinburg Pact forces were able to conquer most of the former León Monarchy and consolidated them into the Federation of Lower Mavona and Federation of Middle Mavona. The goal was to keep both countries weak and reduce territorial disputes, but both countries were plagued with numerous rebellions. Some, including the Agnian Rebellion of 1949, which was supported by Gagium and The Furbish Islands, won de facto independence for countries despite terms of the treaty saying the former Second Coalition countries may not recognize rebellious governments.
The region once again saw heavy fighting during the Third Great War. The Third Coalition held referenda in all territories which led to several cities and countries being split off. Territorial disputes continued, and when occupying forces withdrew in 1989, the Later Post-León Monarchy wars began. A Furbish-led intervention caused much of the fighting to stop by 1996, but tensions remain high and wars continue to be fought into the present day.
