Final answer:
Baldwin IV and Guy of Lusignan had a complex relationship during the Crusades. Baldwin was the king of Jerusalem and Guy, his brother-in-law, became king after his death. Their relationship was marked by tension and conflict.
Step-by-step explanation:
Baldwin IV and Guy of Lusignan had a complex relationship during the time of the Crusades in the 12th century. Baldwin IV, also known as Baldwin the Leper, was the king of Jerusalem and had a great deal of power. Guy of Lusignan, on the other hand, was a prominent nobleman who had married Baldwin's sister Sibylla and became the king of Jerusalem after Baldwin's death.
Their relationship was complicated by a number of factors, including Guy of Lusignan's actions during the Battle of Hattin, where he was captured by the Muslim army and held as a prisoner. Baldwin IV resented Guy and saw him as a weak and ineffective ruler.
Despite their differences, Baldwin did not remove Guy from power during his reign and allowed him to continue ruling Jerusalem. However, their relationship was marked by tension and conflict. Baldwin's decision to appoint his sister Sibylla as queen, and therefore making Guy the king, was seen as a controversial move, and it further strained their relationship.
