The years 892–936, when Silla split into three rival kingdoms until Goryeo reunified them.
See it on the Korean History map →What happened
After peasant tax revolts from 889, Silla lost its provinces to local strongmen (hojok), castle lords who ran their own towns and troops. The Later Three Kingdoms (후삼국) were Silla, now reduced to the Gyeongju area; Later Baekje, founded by Gyeon Hwon in the southwest; and Later Goguryeo, later called Taebong, founded by Gung Ye in the center-north. Wang Geon replaced Gung Ye in 918. After battles at Gongsan (927) and Gochang (930), Silla surrendered in 935 and Later Baekje fell in 936.
Why it matters
It replaced Silla's closed bone-rank aristocracy with new regional elites, who became Goryeo's ruling class.
How we know
The Samguk sagi's late Silla annals and its biographies of Gyeon Hwon and Gung Ye, the Goryeosa, and stone inscriptions at Seon Buddhist temples backed by local lords.
Still debated
Why Silla collapsed so quickly is debated: noble infighting, rigid bone ranks, tax revolts, or the rise of regional lords.

▸Later Three Kingdoms broke up Unified SillaWell documented
The connection
Tax revolts from 889 broke Silla's hold on the countryside. Local strongmen took over towns and troops, and two of them, Gyeon Hwon and Gung Ye, built kingdoms on Silla land. By about 900 Silla ruled little beyond the Gyeongju region, its kings dependent on one rival or the other.
When and how
889–935, beginning with the Sangju revolt of 889 under Queen Jinseong and spreading across Silla's provinces.
How we know
The Samguk sagi's annals of Queen Jinseong record the revolts and lost provinces; its biographies of Gyeon Hwon and Gung Ye describe the breakaways.
Debates and open questions
Confucian historians blamed Queen Jinseong's rule; modern historians point to deeper causes such as noble infighting, rigid bone ranks and the growth of local power.
▸Gyeon Hwon, founder of Later Baekje launched Later Three KingdomsWell documented
The connection
Gyeon Hwon founded the first breakaway kingdom. Gathering troops in the southwest, he took Mujinju (Gwangju) in 892 and in 900 proclaimed Later Baekje at Wansanju (Jeonju), presenting it as revenge for Baekje's destruction by Silla and Tang in 660. Other strongmen, including Gung Ye, soon followed.
When and how
892–900, in the southwest: Mujinju (today's Gwangju) and Wansanju (today's Jeonju).
How we know
His biography in the Samguk sagi gives the dates and quotes his speech at Wansanju about avenging Baekje's last king, Uija.
Debates and open questions
Sources differ on whether his state began in 892 or 900, and on when he first called himself king.
▸Gung Ye, founder of Taebong led a northern state during Later Three KingdomsWell documented
The connection
Gung Ye built the largest of the three states. He rose in a rebel band in the central region, declared Later Goguryeo in 901, renamed it Majin (904) and Taebong (911), and ruled from Cheorwon. He drew on northern loyalty to old Goguryeo and showed open hatred of Silla, reportedly calling it 'the city to be destroyed.'
When and how
901–918, in central Korea: Songak (Kaesong), then Cheorwon, today on the edge of the DMZ.
How we know
His biography in the Samguk sagi and early chapters of the Goryeosa record the names, capitals and campaigns.
Debates and open questions
How much his state rested on Goguryeo identity, versus his own Buddhist claims to kingship, is debated.
▸Later Three Kingdoms ended in reunification by GoryeoWell documented
The connection
Wang Geon won by mixing battle and diplomacy. Victory at Gochang in 930 swung regional lords to his side; generous treatment of Silla led its king to surrender in 935; a family split in Later Baekje sent Gyeon Hwon over to him. At Illicheon in 936 Goryeo destroyed Later Baekje and ended the division.
When and how
930–936, at Gochang (Andong), Gyeongju and Illicheon near Gumi; Wang Geon, Silla's King Gyeongsun, Gyeon Hwon and his son Singeom.
How we know
The Goryeosa and Samguk sagi agree on the sequence and dates of the final campaigns.
Debates and open questions
Some call 936 Korea's first true unification, since Goryeo also absorbed Balhae refugees; others give that title to Silla in 668. Both left Manchuria outside.
