The Ramnulfids, or the House of Poitiers, were a French dynasty of Frankish origin ruling the County of Poitou and Duchy of Aquitaine in the 9th through 12th centuries. Their power base shifted from Toulouse to Poitou. In the early 10th century, they contested the dominance of northern Aquitaine and the ducal title to the whole with the House of Auvergne. In 1032, they inherited the Duchy of Gascony, thus uniting it with Aquitaine. By the end of the 11th century, they were the dominant power in the southwestern third of France. The founder of the family was Ramnulf I, who became count in 835.

Ramnulf's son, Ramnulf II, claimed the title of King of Aquitaine in 888, but it did not survive him. Through his illegitimate son Ebalus he fathered the line of dukes of Aquitaine that would rule continuously from 927 to 1204, from the succession of William III to the death of Eleanor, who brought the Ramnulfid inheritance first to Louis VII of France and then to Henry II of England.

The County of Poitou (Latin comitatus Pictavensis) was a historical region of France, consisting of the three sub-regions of Vendée, Deux-Sèvres and Vienne. Its name is derived from the ancient Gaul tribe of Pictones. The county was bounded on the north by the Duchy of Brittany, the counties of Anjou and Touraine, on the east by the County of La Marche and on the south by the County of Angoulême. The seat of the county was at Poitiers.

Poitou was ruled by the count of Poitou, a continuous line of which can be traced back to an appointment of Charlemagne in 778. From the 950s on, the counts were also dukes of Aquitaine. After the marriage of Eleanor of Aquitaine with Louis VII of France in 1138, the Seneschal of Poitou was responsible for the day-to-day affairs of the county. From 1154, through Eleanor's second marriage, Poitou passed to the kings of England.
