The Songun concept was designed by Kim Jong-il to prioritize military matters and the Korean People’s Army (K.P.A.). However, this resulted in the formation of Songbun, which divides all North Koreans into three groups. The core, which includes professional revolutionaries, descendants of war heroes who perished working or fighting for the country, and peasant families, is the first of these categories. The second group, which includes people who had previously lived in South Korea or China, families of small-scale businessmen, academics, superstitious practitioners, and so on, is in flux. The hostile group, which includes descendants of landlords, capitalists, religious people, political prisoners, and those who aided South Korean forces during the Korean War, is the final category.
