Osman I reigned during which years?

• A. 1250-1270
• B. 1310-1345
• C. 1299-1326
• D. 1285-1310

Answer: (C)

Osman I's reign is dated roughly 1299 to 1326, marking the founding of the Ottoman state. The starting point reflects when Osman established a breakaway principality in northwest Anatolia and began expanding, while the end corresponds to his death, after which his son Orhan I continued building the empire. Some sources vary by a year or two, but 1299–1326 is the most commonly cited range. The other date spans either begin before Osman’s rise or extend beyond his death, so they don’t match the period of his actual governance.
