He is remembered for strengthening royal authority and building Silla into a centralized kingdom.

On the contemporary Naengsuri silla monument, his name was inscribed as Jidoro(至都盧).

Jijeung began his program of legal reform in 502, when he outlawed the custom of burying servants with their masters.

In 503, he formally established the country's name as "Silla," it having previously been represented by a variety of Chinese characters.

Jijeung continued this program in the following years, with a reform of ceremonial dress in 504 and of local administration in 505.
