Fulk (fŭlk) [key], 1092–1143, Latin king of Jerusalem (1131–43), count of Anjou (1109–29) as Fulk V, great-grandson of Fulk Nerra. He journeyed (1120) to the Holy Land as a pilgrim and returned there in 1129, making his son, Geoffrey Plantagenet, count of Anjou as Geoffrey IV. Having taken as his new wife Melisende, daughter of King Baldwin II of Jerusalem, he succeeded his father-in-law in 1131. Fulk's reign was disturbed by dissensions among the Latin princes and by the raids of the Turks, whose prisoner he was for a time in 1137. He was succeeded as king of Jerusalem by his son by Melisende, Baldwin III.
