ABSTRACT
Consequent on the conquest of the northern province of Korea by the Emperor Yo of Zui in a.d. 614, the military prestige of the continent increased rapidly over the Korean peninsula, and it had reached its highest point during the reign of the Emperor Taiso of To Dynasty. As Japan was kept informed of this situation through her Imperial messengers dispatched to To, the return home of students, and the interchange of priests for study, she kept a vigilant watch over To.
