I want to know the answer to the following question:
When was the reign of sultan Mehmed VI?
All the background I'm provided with is that "As such, the last Ottoman sultan Mehmed VI (r. 1918–1922) was a direct patrilineal (male-line) descendant of the first Ottoman sultan Osman I (r. 1299–1326), which was unparallelled in both Europe (e.g. the male line of the House of Habsburg became extinct in 1740) and in the Islamic world.". Is that enough to answer the question?
