Imad ad-Din Zengi
Bohemond made peace with Imad ad-Din Zengi II, the Zengid ruler of Aleppo, in May 1182. However, Imad ad-Din was forced to surrender Aleppo to Saladin on 11June 1183. Fearing an attack on Antioch, Bohemond sold Tarsus to Roupen III, Lord of Armenian Cilicia, to raise funds. BaldwinIV of Jerusalem promised to send 300 knights to Antioch. Saladin did not invade the principality and signed a peace treaty with Bohemond. Bohemond attended the assembly that BaldwinIV had summoned to discuss the administration of the Kingdom of Jerusalem in autumn 1183. At the meeting, Guy of Lusignan was dismissed as regent, and his five-year-old stepson, Baldwin, was proclaimed co-ruler. A charter shows that Bohemond was in Acre in April 1185, suggesting that he was present when the leper BaldwinIV died around that time.
