START
Korea was under the rule of Japan, until Kim Il-Snail, a communist snail, revolted against the Japanease rule and had declared war on the Vatican, announcing all Catholics were enemies of the state. The South had succeeded also from Japan, and had announced to be in support of the Vatican.
WAR
South Korea launched several minor attempts into Snailrea, which were vast failures. Snailrea had begun slowly approaching and nearly annexed South Korea, until finally, HRE troops under Archbishop Bergoglio arrived. Bergoglio, as we know to be Francis, would fight tooth and nail, eventually routing the Snails and pushing them to China. The war under archbishop Bergoglio was short, and after recognizing Bergoglio's great and swift victories, Pope Pious XII made Bergoglio a Cardinal. Snailrea however was able to resist for years, and regained control of the country after HRE troops were pulled out to fight in VietFlabe.
TODAY
Francis had never had the interest to regain Snailrea, and eventually just left them alone. Cory Strudel would eventually take control, and would begin the complete slaughter of all communist snails, leaving the old communist snail dynasty dead, and Snailrea was over. It is now under Jucheist Kim Jong-un, who is Cory Strudel. It is very well accepted that if the Snails hadnt revolted and the HRE did not send Francis, its likely Francis would have never became the Pope.
