Final answer:
The Fourth Crusade resulted in failure due to a diversion from their original goal, lack of unity and leadership, and logistical challenges.
Step-by-step explanation:
The Fourth Crusade resulted in failure for several reasons. The correct answer is D. Crusaders never even reached the Holy Land and instead fought in the Byzantine Empire.
The Fourth Crusade was initially intended to recapture Jerusalem from the Muslims. However, the Crusaders ended up sacking Constantinople, the capital of the Byzantine Empire, in 1204. This diversion from their original goal weakened their efforts and ultimately led to failure.
The Crusaders never truly unified, and different factions within the Crusader army had differing motivations and interests. Additionally, they faced logistical challenges and lacked proper leadership. These factors contributed to their inability to achieve their objective and marked the failure of the Fourth Crusade.
