The conquest of Constantinople by the Ottomans in 1453 C.E. most directly resulted in which of the following?

The First Crusade was called in 1095, well before the fall of Constantinople. Although later Crusades were influenced by the ongoing conflicts between Christians and Muslims, the conquest of Constantinople did not directly initiate another call for crusade, as it occurred centuries after the initial crusading movements.

While the Ottomans did control key trade routes after the conquest, the assertion that it cut off most trade is misleading. Trade continued, albeit under different conditions and regulations imposed by the Ottomans, who facilitated trade through their empire rather than completely halting it.

Although the fall of Constantinople did bolster the spread of Islam in the region, it did not result in a direct or immediate spread into Western Europe. The political and cultural dynamics of the time were complex, and while the Ottomans expanded their influence, the spread of Islam was gradual and met with resistance in predominantly Christian areas.
