Duchy of Longueville
It emerged as the Longueville lordship , which over time was expanded to include Longueville County and finally to a duchy in 1505, before it expired in 1694 when the last duke died.
It was founded by William the Conqueror as a rule for his confidante Gautier Giffard from the noble family Giffard . At the beginning of the 13th century it belonged to William Marshal, 1st Earl of Pembroke , the regent of England .
During the Hundred Years War , Longueville was confiscated by King Philip IV of France and given to his minister Enguerrand de Marigny in 1305 . In 1314 the county was confiscated again and Marigny was executed in 1315.
1319 got Louis , Count of Évreux Longueville. It then belonged to the family of the Counts of Évreux until his grandson, King Charles the Evil of Navarre , had to cede the area to King Charles V of France in 1356 . Charles V gave Longueville to Charles von Artois , the younger son of Robert III. , Pretender in Artois . Charles of Navarre got Longueville back, but had to give it back in 1364.
Charles V donated the county on May 27, 1364 to Bertrand du Guesclin , the Connétable of France , with the county of Tancarville , which until then was under the county of Longueville, made a royal fief and the city of Montivilliers ( Seine-Maritime ) into the Domaine royal was acquired.
During the English occupation of the country, Longueville was owned by Gaston de Foix , Count of Bénauges . King Charles VII gave them to Archibald Douglas and finally to John of Orléans , the Count of Dunois and companion in arms of Joan of Arc , who bequeathed them to his descendants.
After the heirless death of Duke Jean Louis in 1694, Longueville fell back to the crown ( domaine royal ).
