Caliphate is a position in which elected people leading muslims in a religious way beside their politic and military authorities that preside State of Islam after the prophet Mohammed, have. As one of the reasons of so many events’ in the historical period directly or indirectly, caliphate, no doubt, has become the most debated topic even in current time. Differences between sources towards passing of caliphate on Ottomans and discrepancies between reality and comments relying on these sources, urged us to study about it. We tried to study the attitudes of Sultans’s towards caliphate before and after the expedition of Egypt which became symbolic event of caliphate’s passing on Ottomans, focusing on particularly first-hand sources and documents. We eventually reached some points during our study: In contrast to general idea, caliphate couldn’t protect its importance throughout history, caliphs has lost their authorities in time. Despite the endeavors of revival, it never become as strong as it was once. It was reached that the reason of expedition into east by Sultan Selim I, was more unique than receiving caliphate and different from the ones before him, that Selim I hadn’t so reverence for caliph, that even after the expedition, he caliphate title wasn’t in use in the that time sources and that the title was used by a few writers deliberately.
