The Later Three Kingdoms period (889–936 AD) of ancient Korea saw a partial revival of the old three kingdoms which had dominated the peninsula from the 1st century BC to the 7th century AD. After the Unified Silla kingdom had ruled Korea alone from 668 AD, it slowly began to decline and the power vacuum this created led to several rebellious states rising up and taking on the old historical names of Korea's ancient kingdoms. A messy period of alliances and in-fighting followed, but one state would once again establish a dominant position – Goryeo, itself named in homage to the earlier northern Goguryeo kingdom – and form a unified Korean state and a dynasty which would last almost 500 years.

The Fall of Silla

The

Bone rank system
meant that few could rise above the position of their birth and ideas and innovation were stifled. The aristocracy began to resent the power and waste of the king, landowners resisted centralised control, and the peasantry grew more and more rebellious over the incessant taxes levied upon them. The state was falling apart from within.

The weakness of the central Silla government meant that local warlords and strongmen, always difficult to bring under state control at the best of times, now ruled their own territories as they pleased. Banditry swept across the peninsula, particularly infamous examples being Chongill, Kihwon, Yang Kil, and a group known as the Red Pantaloons (Chokkojok).

Kyŏn Hwŏn and Kung Ye

This period of political turmoil which turned into a free-for-all for control of Korea is referred to as the Later Three Kingdoms period (889-936 AD). Kyŏn Hwŏn (867-936 AD), a peasant leader and Silla army officer, took advantage of the political unrest in 892 AD and made himself military governor of the city of Muju. By 900 AD, Kyŏn became more ambitious and, joining forces with the bandit Yang Kil, formed a revival of the old Baekje (Paekche) kingdom in the south-west portion of the peninsula. He chose Wansan (modern Jeonju) as his capital.

Meanwhile, an aristocratic Buddhist monk leader,

Gaesong) and then Cheorwon. He also twice changed the name of his kingdom – to Majin in 904 AD and Taebong in 911 AD – illustrative of his unstable character. One thing that never changed was Kung's hatred of Silla
and his insistence that his subjects always refer to it as the 'nation of the damned.'

There then followed a protracted power struggle for control of the peninsula.

Wang Kŏn who probably had a hand in his hated predecessor's assassination. Wang had already distinguished himself as a naval commander, capturing several islands and blocking Baekje's trade with China and Japan. Wang selected the new name of Goryeo (Koryo) and moved the capital to Songak (modern Kaesong
) where his father had long been a wealthy merchant and local headman.

Wang Geon's Unification of Korea

Geochang to a force led by Wang. Back at the Baekje capital, Kyŏn Hwŏn faced a rebellion led by his son Kyŏn Sin-gŏm
, who, displeased that his father had favoured his younger brother as next in line for the throne, imprisoned Kyŏn Hwŏn.

Wang was now in possession of most of

Hongseong), refugees from the northern Manchurian state of Balhae
(Parhae) felt the situation stable enough to return to Korea.

Later Goguryeo territory, appealed to his old enemy Wang for help to remove Kyŏn Sin-gŏm. Kyŏn led a Goguryeo army to Baekje, and the resulting civil war and death of both Kyŏn Sin-gŏm and Kyŏn Hwŏn in 936 AD, greatly weakened Baekje and allowed Wang to finally unify the country once again under the name of Goryeo, origin of today's name for Korea. Wang, posthumously given the title of Taejo of Goryeo or 'Great Founder,' established a dynasty which would rule Korea
for the next five centuries.
