Ahmed I was the sultan of the Ottoman Empire from 1603 to 1617. Ahmed's reign is noteworthy for marking the first breach in the Ottoman tradition of royal fratricide; henceforth, Ottoman rulers would no longer systematically execute their brothers upon accession to the throne. He is also well known for his construction of the Blue Mosque, one of the most famous mosques in Turkey.
