Generals and Scholars is the first work in English to examine fully military rule during the Koryo. Although it lasted for only a century, the period was one of dynamic change—a time of institutional development, social transformation, and the reassertion of the civil service examination and Confucian ideology coupled with the flowering of Son (Zen) Buddhism. (When confronted with fundamental matters of rule, however, Ch'oe leaders frequently opted for the status quo and in the end aligned with many traditional civil elites to preserve their power.) The traditional tension between civilians and the military was eased as both came to accept the primacy and necessity of civilian values. Koryo generals, unlike those in Japan, learned they could govern more readily by relying on civil leaders administering a strong central government than on a call to arms. Institutional innovations from this period survived well into the next and Son Buddhism continued to flourish throughout the country.
