John II, Count of Soissons

He was well-connected with the trouvères: his younger brother Raoul was one and he received the dedication of a song by Pierrekin de la Coupele.

John's first marriage was to Mary (died c. 1241),[3] the heiress of Roger du Thour et de Chimay and his wife Agnes.

John's second wife was Matilda (died 12 May 1256), the daughter and eldest surviving child of Sulpice III of Amboise and Isabella, who had inherited the county of Chartres from her father, Theobald VI, Count of Blois.

After imprisoning several ecclesiastics, Louis IX and the Archbishop of Reims, Henry of Dreux, intervened to obtain an agreement between the feuding parties.

In 1242 John supported Louis against the rebellious Hugh X of Lusignan and the invading Henry III of England in a conflict that became known as the "Saintonge War".
