The cause of the war in the Principality of Gion

Dissatisfaction caused by forced immigration and tax recovery in 1950s.

After the federal government launched the space migration plan to solve the problem of the earth's population burden, in order to reduce the pressure on the earth's population and encourage people to settle in the universe, during this period, the federal government provided welfare policies including housing, land, 100% employment, free medical care, education, etc., so as to encourage more people to settle in all aspects. The early pioneers of the universe also put forward the proposal of "moving most people into the universe in order to restore the earth's environment" in the federal parliament, which won the favor of countries with high population pressure on the earth (such as China and Japan in the Group of Eight). When 9 billion people immigrated to the universe, the federal government began to abolish the tax exemption policy formulated in the early years to attract immigrants, and the residents of the universe began to pay personal income tax, social insurance tax and other general taxes (excluding special taxes) like the residents of the earth, but the tax rate was still lower than the earth standard. The inevitability of abolishing this policy lies in the fact that the early immigration expenses and colonial satellite construction expenses were borne by the taxpayers of the earth. With most people moving to the universe, a situation has gradually formed in which a few taxpayers (earth residents) support most non-taxpayers (space residents). In the process of immigration, the federal government also paid a lot of financial expenditure. Considering the above factors, it is also reasonable for the federal government to resume taxation on cosmic residents. For those forced immigrants (similar to demolition, home in the universe), the federal government's immigration fee is a long-term interest-free loan for the difference between the house and part of the transportation cost, which is not enough by the government's financial expenditure. However, in order to reduce the burden of forced immigrants, the federal government divided the interest-free repayment model of immigration fees into several generations to pay off, thus reducing the living burden of one generation. However, the restoration of taxes and forced immigration have caused dissatisfaction among some astronauts who have been accustomed to tax exemption for 50 years and some astronauts who have been forced to emigrate. There are some idealists and political speculators among them. The independence movement initiated by deacons in SIDE 3 undoubtedly provided a paradise for these people to play. Killian Zabi, the initiator of the one-year war, and his Zabi family are one of these political speculators.

Side 3 Common psychological problems caused by residents' living environment

During the year-long war, the principality's army committed atrocities such as killing SIDE residents with NBC weapons, establishing a "centralized management community", and abusing prisoners of war. The Zabi family's success in taking power in SIDE 3 and gaining public support have a lot to do with the long-term psychological problems of SIDE 3 residents. First of all, of the seven faces built by the Federation, three are the only colonies on the back of the moon, where the earth is invisible to the naked eye. This objective environmental problem makes it easy for people living in colonies to abandon their own people, just like a lonely boat drifting in the sea, unable to find coordinates and land. Unable to overlook the earth, residents living in SIDE 3 have completely lost the necessary "mental health care". After Jean Zimm Deacon went to SIDE 3 to engage in the independence movement, the original open colony had to be transformed into a closed colony to accommodate more people due to the explosive population growth. Because the closed colony at that time was still in the early stage of experimental exploration, the adjustment of light source and weather was not mature technically, and it had to rely on microwave transmission from the other side, the surface of the moon and peripheral power plants to maintain illumination, and the switching between day and night only stayed on the ability to turn on the lights. The way to switch between day and night is extremely stiff, just like the fluorescent lamp (Yuba) in the bathroom, which makes people extremely uncomfortable. Therefore, the three-sided residents living in the closed colony lost their normal life of switching day and night by reflecting natural light through the mirrors in the open colony. Although it seems like a trivial matter, it is easy for those who can only enjoy fluorescent lamps because they can't see natural light all the year round. (In the real world, some Nordic countries living in high latitudes are extremely day and night, and rarely see sunshine all year round. People there can only simulate sunlight indoors with fluorescent lamps. These countries are also the countries with the largest number of depression patients in the world.). At the same time, SIDE 3 is the only colony with heavy industry. Its main industry comes from the development of the asteroid belt, which is extremely dangerous. On average, people die in accidents in the asteroid belt every day. On the other hand, SIDE 3, which relies on heavy industry, has a considerable proportion of the population engaged in this dangerous occupation, and most of these people do not live in colonies. The vibration of the living environment, commuting, lack of green space and weightlessness caused by heavy industry will have a psychological impact on people engaged in this industry (refer to the gloomy character of the heroine Wen Hai in Goddess of Death).
