Ferdinand of Portugal ( port : Fernando, old French : Ferrand; * 1188 ; † 1233 ) was a Count of Flanders and Hainaut from 1212 as the husband of Countess Johanna . He was a younger son of King Sancho I of Portugal .
Ferrand was married to Countess Johanna on January 1, 1212 through the mediation of his aunt Mathilde, the widow of Count Philip of Flanders , who was the ward of King Philip II of France at the royal court in Paris . On the trip to Flanders, however, the couple were captured by Crown Prince Ludwig , who wanted to force the handover of the inheritance of his mother, Isabella von Hennegau , one of Johanna's aunties. This legacy included the county of Artois , but was once given by Joan's father, Count Baldwin IX. forcibly retained after Isabella's death (1190).
After Johanna and Ferrand ceded the cities of Aire-sur-la-Lys and Saint-Omer to the Crown Prince, they were released. However, as a result of these events, Ferrand changed into an oppositional stance towards the crown. When King Philip summoned his vassals for an invasion of England in Boulogne in 1213 , Ferrand refused to take part in the army. After the king had to cancel the invasion, he turned with the army towards Flanders, which he quickly subjugated; Ferrand could only stay in Walcheren . Together with the also renegade Count Rainald I von Dammartin , he fled to England in the autumn of 1213, where they paid homage to King John Ohneland in January 1214 and thus made themselves guilty of felony against the King of France . A little later, Ferrand landed with an army, supported by English knights under William Longespée , again on the coast of Flanders and united there with an army of the Roman-German Emperor Otto IV to lead the decisive blow against the King of France. The allies were defeated but on July 27, 1214 in the battle of Bouvines , Ferrand was wounded and was captured by King Philip. He was imprisoned in the fortress tower of the Louvre for more than twelve years ; during this time Countess Johanna von Flanders and Hainaut ruled alone.
Only after the death of King Louis VIII Ferrand was released again by the ruling Queen Mother Blanka of Castile in January 1227. He had to pay a ransom of 25,000 livres and hand over the cities of Douai and Lille to the Crown. From then on he was loyal to the crown and supported the regent in the fight against the rebellious barons around Peter Mauclerc . He died in 1233 and was buried in the Cistercian Abbey of Marquette.
His daughter Maria, who was born in 1231 but died in 1235, emerged from his marriage to Countess Johanna.
