Count of Poitiers in the context of "Aquitaine"

Richard I (8 September 1157 – 6 April 1199), known as Richard the Lionheart or Richard Cœur de Lion (Old Norman French: Quor de Lion) because of his reputation as a great military leader and warrior, was King of England from 1189 until his death in 1199. He also ruled as Duke of Normandy, Aquitaine, and Gascony; Lord of Cyprus; Count of Poitiers, Anjou, Maine, and Nantes; and was overlord of Brittany at various times during the same period. He was the third of five sons of Henry II of England and Eleanor of Aquitaine and was therefore not expected to become king, but his two elder brothers predeceased their father.

By the age of 16, Richard had taken command of his own army, putting down rebellions in Poitou against his father. Richard was an important Christian commander during the Third Crusade, leading the campaign after the departure of Philip II of France. Despite achieving several victories against his Muslim counterpart, Saladin, he was ultimately forced to end his campaign without retaking Jerusalem.

Warinus of Poitiers (also Warin, Guerin, Gerinus, Varinus; died 677 AD) was the Franco-Burgundian Count of Poitiers and later Count of Paris. He was from a noble family. He was martyred at Arras in 677.

Renaud (795 – 843) was Frankish Count of Herbauges, Count of Poitiers and Count of Nantes. His name is also spelled Rainaldus or Ragenold, and he is sometimes known as Reginald in English. He is referred to as Renaud of Aquitaine, but seems to have been a member of the Rorgonid family of Maine.

The County of Herbauges consisted of three pagi south of the Loire: Arballicus (Herbauges), Metallicus (the Mauges), and Teofalicus (Tiffauges) and was separate from the County of Poitou, of which Renaud also appears to have been Count. His appointment as Count is prior to July 835 when he appears in a battle against the Normans in Noirmoutier.

Ranulf I (also Ramnulf, Rannulf, and Ranulph) (820–866) was a Count of Poitiers (from 835) and Duke of Aquitaine (from 852). He is the son of Gerard, Count of Auvergne. Few details are known about Ranulf I, except that he died in 866 in Aquitaine from wounds received in the Battle of Brissarthe against the Vikings (in which Robert the Strong also died).

Aymar or Adémar (died 2 April, 926) was Count of Poitiers from 890 to 902 and Count of Angoulême from 916 to 926.

William III (913 – 3 April 963), called Towhead (French: Tête d'étoupe, Latin: Caput Stupe) from the colour of his hair, was the "Count of the Duchy of Aquitaine" from 959 and Duke of Aquitaine from 962 to his death. He was also the Count of Poitiers from 935 and Count of Auvergne from 950. The primary sources for his reign are Ademar of Chabannes, Dudo of Saint-Quentin, and William of Jumièges.

William VIII (c. 1025 – 25 September 1086), born Guy-Geoffrey (Gui-Geoffroi), was duke of Gascony (1052–1086), and then duke of Aquitaine and count of Poitiers (as William VI) between 1058 and 1086, succeeding his brother William VII (Pierre-Guillaume).
