Henanfu or Henan Prefecture, also known as Luoyang, was a fu (superior prefecture) in imperial China in modern Henan, China, centering on modern Luoyang.[3] It existed (intermittently) from 713 to 1913. During the Later Tang dynasty (923–937) it was the national capital. For most of the Tang dynasty (before 907) it was known as the "Eastern Capital" (東都), and during the Northern Song dynasty (960–1127) it was known as the "Western Capital" (西京). From 1127 to 1234 the Jurchen conquerors named it Jinchang Prefecture (金昌府), also known as "Central Capital" (中京).[4] For these reasons, Henan Prefecture was also colloquially called Luojing (洛京, "Luo Capital").
