christianity in the late middle ages quiz h whg: modern world hist a o / europe divided 4. why were the crusades considered ultimately unsuccessful? large numbers of crusaders converted to islam after reaching the middle east. popes who led the catholic church after 1250 a.d. lost interest in crusades. most crusaders never actually made it to jerusalem—they gave up and went home. later crusades failed in their mission to regain and maintain control of jerusalem.

Explanation:

The main goal of the Crusades was to regain and maintain Christian control of Jerusalem. Later Crusades were unable to achieve this objective, which is why they are considered ultimately unsuccessful. The other options are either inaccurate (large - scale conversions to Islam did not happen, and it's an over - generalization to say most Crusaders never made it to Jerusalem) or not the main reason for overall failure (popes losing interest is not the central reason for failure).

Answer:

Later Crusades failed in their mission to regain and maintain control of Jerusalem.
