In much of the English-speaking world, the country ruled by Kim Jong Un is known simply and succinctly as North Korea. Yet this, of course, is not the country’s official name — the much longer Democratic People’s Republic of Korea — and Pyongyang shuns the shorter “North Korea” in all official and even semi-official dealings as a label legitimizing the peninsula’s division.

There is a degree of hypocrisy in these statements. Northerners themselves normally prefer to just say “the Republic” rather than to break their tongue over the convoluted sobriquet. But what’s funnier, in a rather dark way, is that the DPRK once referred to itself by a wrong name for several years, in a little-known episode that highlights the enduring political culture of fear north of the DMZ.
