👉 Château-Landon in the context of Ermengarde of Anjou, Duchess of Burgundy
Ermengarde of Anjou (c. 1018 – 18 March 1076), known as Blanche, was a Duchess consort of Burgundy. She was the daughter of Count Fulk III of Anjou and Hildegarde of Sundgau. She was sometimes known as Ermengarde-Blanche.
Ingelger (845 - 888), also called Ingelgarius, was a Frankish nobleman, who was the founder of the County of Anjou and of the original House of Anjou. Later generations of his family believed that he was the son of Tertullus (Tertulle) and Petronilla.
Around 877, he inherited his father Tertullus' lands in accordance with the Capitulary of Quierzy, which Charles the Bald had issued. His father's holdings from the King included Château-Landon in beneficium, and he was a casatus in the Gâtinais and Francia. Contemporary records refer to Ingelger as a miles optimus, an excellent soldier.
Gâtinais (pronounced[ɡɑtinɛ]) or Gâtine (pronounced[ɡɑtin]) was a province of France, containing the area around the valley of the Loing, corresponding roughly to the northeastern part of the département of Loiret, and the south of the present department of Seine-et-Marne. Under the Bourbons, the Gâtinais had already been divided between the provinces of Île-de-France and Orléans. In the words of the modern tourist slogan for the "two Gâtinais", it lies between the Seine and the Loire.
Under the Franks, Gâtinais was the pagus Wastinensis (eventually to become Wasteney in the 20th century), (or Vastinensis) one of five belonging to the Archbishop of Sens. The west part of Puisaye and the archbishop's other fiefs in the northwest of the modern department of Yonne, west of that river, are also often considered part of Gâtinais; as is the area around Étampes in the present department of Essonne. Around the 10th century, the main town of this province was Château-Landon, and a twenty-five-mile circle around Notre-Dame de Château-Landon basically comprised it.
