Why did the Christians and the Muslims hate each other in the third crusades?

The animosity between Christians and Muslims during the Third Crusade stemmed from a combination of religious zeal and territorial disputes. The Crusades were framed as holy wars, with Christians seeking to reclaim Jerusalem, which they viewed as a sacred city, while Muslims, led by figures like Saladin, sought to defend their land and faith from what they perceived as foreign invaders. This conflict was exacerbated by centuries of tension, cultural differences, and previous violent encounters. Ultimately, the clash was fueled by both deep-seated religious convictions and the desire for power and control over key regions.
