Fulk I of Anjou, called the Red, was son of viscount Ingelger of Angers, and was the first count of Anjou from 898 to 941. He increased the territory of the viscounty of Angers and it became a county around 930. During his reign he was permanently at war with the Normans and the Bretons. He occupied the county of Nantes in 907, but abandoned it to the Bretons in 919. He died around 941 and was succeeded by his son Fulk II.
Fulk V of Anjou (1089/1092 – November 13, 1143), also known as Fulk the Young, and after 1131 as Fulk of Jerusalem, was Count of Anjou from 1109 to 1129, and king of Jerusalem from 1131 to his death.
Fulk was born between 1089 and 1092, the son of Count Fulk IV of Anjou and Bertrade de Montfort.
Fulk and Melisende became joint rulers of Jerusalem in 1131 with Baldwin II's death.
