Final answer:
The initial advance on Jerusalem during the First Crusade was slow due to difficult terrain, resistance from Muslim forces, and lack of cohesion among the Crusaders.
Step-by-step explanation:
The initial advance on Jerusalem during the First Crusade was slow due to a combination of factors.
- The Crusaders faced numerous obstacles in their journey, including difficult terrain, harsh weather conditions, and a lack of resources. This slowed their progress and made it challenging to maintain a steady advance.
- The Crusaders also encountered strong resistance from the Muslim forces defending Jerusalem. They faced fierce battles and had to siege several cities before reaching Jerusalem.
- Additionally, the Crusaders were not a cohesive and organized army. They consisted of various groups with different motivations and goals, which often led to conflicts and delays.
Overall, these factors contributed to the slow initial advance on Jerusalem during the First Crusade.
