Adela of Hamaland (also Adela of Elten) (952 – died after 1021), was countess of Hamaland in the Netherlands in about 973–1021. She was also the regent of Renkum in circa 983–?, likely as regent for her son Dirk of Renkum. Her claim on the inheritance of her father caused a conflict with her sister Liutgard of Elten, which lasted from 973 until 996. She first married Count Immed of Renkum (d. 983), the father of her son, and later Count Balderik of Hamaland, whom she made her co-regent by marriage.
Adela was the daughter of Count Wichman II of Hamaland (d. 973) and Liutgard of Flanders (d. 962), daughter of Arnulf of Flanders and Adele of Vermandois. Adela was the younger sister of Liutgard (d. 995), who became the abbess of Elten Abbey, which was founded by their father. Adela's first husband was Count Immedd of Renkum, a member of the Immedinger dynasty, with whom she had five children.
At the death of their father in 973, the emperor made Elten Abbey a Princely Imperial Abbey and Liutgard was thereby given sovereign status as princess abbess of Elten. A succession war erupted between the sisters, as Adela claimed the county as sovereign Countess of Hamaland and Liutgard claimed all the county as Elten territory. Liutgard had her vassal Balderich attack and burn Adela's fortress down.
In 983, Adela became a widow and regent of the county of Renkum as guardian of her minor son. She occupied the territory of Liutgard, but was forced by the emperor to end the occupation.
Upon the death of Liutgard in 995, Adela married her sister's former vassal Balderik, and he ruled as Count of Hamaland by marriage. One year later, the succession dispute between Adela and Elten was finally resolved by mediation of the Otto III, Holy Roman Emperor: the territory formally named county of Hamaland was split between Elten Abbey and Adela of Hamaland, and Adela's spouse Balderik was formally named the successor of her father. In 999, Adela and Balderik conquered the land given to Elten as well.
By their contemporaries, Balderik was regarded merely as the tool of Adela, and when his rival Wichman van Vreden was murdered in 1016, she, rather than Balderik, was blamed. The followers of Wichman laid siege to Adela's fortress, Uplade, where Balderik left her and escaped, leaving her to defend the fortress herself. Adela did not have enough soldiers, and therefore dressed women as soldiers and used them in her defense as well. The fortress was eventually captured by the enemy, but Adela was allowed to leave unharmed.
With Immed, Adela had the following children:
Adela has traditionally been given an infamous reputation in history. Contemporaries reviled her as a “treacherous wife” (perfida coniunx); a “second Salome” (secunda Herodiadis); and as acting like Jezebel (et sicut Hiezabel). The medieval historian Karl Leyser called Adela "the Lady Macbeth of the Lower Rhine".
