Etymology and terminology
Main Article: Name of Sehwang Federation

Sehwang, the national name of the Sehwang Federation, came from the efforts to build a unified economy of these countries as the national movement began in earnest in the early 19th century and gradually began to unite the autonomous communities of immigrants into one nation. At that time, even if people tried to unite migrants and natives to establish a single nation, there was nothing to put forward a symbol because they were not one nation. The immigrants were also divided into 3 ethnic groups, and the use of 'indigenous group' word also referred to 6 ethnic groups, etc. It was hung and used as a badge. Here, the name of the country/place called Sehwang was derived from Haixiao characters, which were commonly used by immigrants, with characters meaning bamboo and a character meaning insignia.

It has become known that this is Sehwang in the Sincheon language, and the country name itself is also called Sehwang. These, in turn, were similarly transliterated in the languages of the aborigines. So Sehwang is a value-neutral place name. For this reason, the meaning of Sehwangnese is changed and used in such a way that everyone identifies themselves as Sehwang people first and then identifies what kind of ethnicity they are.

Federal entities and administrative divisions
As long as there was the establishment of the Sehwang Federation in the coexistence of migrants and natives, there was no colonial rule. As a result of this influence, the Sehwang Federation gave extensive autonomy as a federal entity to the administrative district called 'Province(道, 도)', the largest administrative district experienced by the migrants. As such, Sehwang Federation uses the provincial system rather than the state system. Since the 1940s, due to the rapid population growth in major cities, there has been a large demand for wide-area administration in cities that cannot be addressed by the provincial system. Eventually, in 1950, this problem was solved by implementing a metropolitan system by dividing major cities into metropolitan cities that 'exercise extensive autonomy only in the administrative districts of major cities'. Accordingly, the Sehwang Federation is composed of 74 provinces and 8 metropolitan cities.

National railway history
Due to late industrialization, it was not until 1878 that the first railway from Gusan to Gwangsun via Jinyang and Geumgyo was opened. Afterwards, the railroad network connecting major cities across the country was opened by 1915, mainly in coastal areas. It was completely dieselized in the 1930s, but despite mile train transportation, the limit of transportation capacity was not overcome as a result of low turnover. Considering that electrification began in 1920 to secure the safety of railway transportation in the high mountain area, double-tracking and electrification of main lines were started in 1935 to increase the turnover rate and improve speed. As a result, all Sehwang's railways were electrified in 1946, and the trunk line secured a curve radius of more than 2000m and ran at more than 160km/h.
