What I’ve discovered

 

 King Tamdok (c. 374 to 413 A.D.) was posthumously given the title Kwang Gae, which means

 ‘broad enlarger of territory’.

 

By advancing north and south, Kwang Gae overtook Paekche land to the north of the Han River;

he also expanded into much of Manchuria and parts of Inner Mongolia. He eventually ruled two thirds

 of the Korean peninsular.

 

In 392 A.D. King Kwang-Gae is recorded to have had nine Buddhist temples built.

 

 He did not quite succeed in unifying Korea, despite aiding Silla when they were attacked by the

Japanese pirates.

 

Kwang Gae’s son who also went on to expand his territory had a 24 foot monument erected in

414 A.D. next to his father’s tomb to record his achievements.

The monument had 18000 Chinese characters carved into it, which record his conquests of

64 walled cities (sometimes referred to as castles) and 1,400 villages.

 

This monument now finds itself located in present day Southern Manchuria.

 

He died aged just 39.

 King Kwang-Gae r. 391-413 A.D.
