For decades North Korea has been one of the world's most secretive societies. It is one of the few countries still under nominally communist rule.
North Korea's nuclear ambitions have exacerbated its rigidly maintained isolation from the rest of the world.
The country emerged in 1948 amid the chaos following the end of World War II. Its history is dominated by its Great Leader, Kim Il-sung, who shaped political affairs for almost half a century.
