Goguryeo, a Korean kingdom, had a long line of rulers. Listed below are the rulers of Goguryeo in order of their reign.
Goguryeo, along with every developed East Asian state at the time wrote using Chinese characters, which was the universal writing system in East Asia.
Upon unifying China, the Sui dynasty attempted to establish dominance over all its neighbors and declare itself as the region's superpower. It managed to subjugate Japan, Vietnam, Tibet, and Southern Korea but Goguryeo (the most powerful of the three kingdoms of Korea) refused to acknowledge the Sui Dynasty's supremacy. This caused the Sui to invade Goguryeo resulting in the Goguryeo-Sui war. Goguryeo managed to defeat the Sui dynasty and after two failed invasions, the Sui dynasty failed economically which resulted in resentment of the Chinese people and ultimately the downfall of the dynasty. In essence, Goguryeo was the most significant factor contributing to the downfall of the Sui.
The three kingdoms in Korea were named Goguryeo, Baekje, and Silla.
King Dongmyeong, also known by the birth-name Jumong (surname: Go) was the first Taewang of Gorguryeo. source: Wikipedia
