In 901, the general Gung Ye rebelled against Later Silla and founded Later Goguryeo (renamed to Taebong in 911), which considered itself to be a successor of Goguryeo. Later Goguryeo originated in the northern regions, including Songak (modern Kaesong), which were the strongholds of Goguryeo refugees. Later Goguryeo's original capital was established in Songak, the hometown of Wang Geon, a prominent general under Gung Ye. Wang Geon was a descendant of Goguryeo and traced his ancestry to a noble Goguryeo clan. In 918, Wang Geon overthrew Gung Ye and established Goryeo, as the successor of Goguryeo, and laid claim to Manchuria as Goryeo's rightful legacy. Wang Geon unified the Later Three Kingdoms in 936, and Goryeo ruled the Korean Peninsula until 1392.
