Reader's Guide
The Korean Peninsula's significance lies in its long history of kingdoms and dynasties, its cultural and technological developments (such as the creation of Hangul and Confucian influence), and its modern division into two ideologically opposed states. The demilitarized zone approximates the original partition, and tensions remain high.
