Raynald of Châtillon
In order to carry out his attack on Egypt, Baldwin needed naval support. He thus sent Raynald of Châtillon to lead an embassy to Emperor Manuel, Raynald's stepson-in-law, in Constantinople in the winter of 1176-77. Manuel agreed to take part in the invasion in return for the establishment of Byzantine protectorate over the kingdom and restoration of the Orthodox patriarch, Leontius II, in Jerusalem. As Raynald's mission was successful, Baldwin consented to his marriage with the lady of Oultrejordain, Stephanie of Milly.
