Trần Thái Tông
This title was first awarded to Lê Văn Thịnh (d.1096). Subsequent exams starting in 1247 and onward were divided into three first class grades along the Chinese model with "trạng nguyên" as the first of three prizes. The first "trạng nguyên" under this system was Nguyễn Hiền. The full list of "trạng nguyên" therefore includes 55 scholars if beginning from Lê Văn Thịnh, but only 49 if commencing from Nguyễn Hiền (awarded 1247, in the reign of Trần Thái Tông).
