Nearly all references to Kim (pertaining to RationalWiki's mission) will refer to the crazies that have ruled North Korea from 1948 and onward. They are known as the Kim family or the second "Kim dynasty." In North Korea, the family is officially referred to as the "Mount Paektu Bloodline" (sometimes spelled "Baektu"). The mountain is traditionally sacred to Koreans (North and South) and neighboring Manchus; the Kim family appropriated its name for propaganda purposes.
Kim is also the most common family name on the Korean Peninsula, a common first name outside of Korea, an edible seaweed, and an ethnic group in Chad.
