Ottoman Empire - Silver Akce - Ahmed I (18 April 1590 – 22 November 1617) 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.[5] He is also well known for his construction of the Blue Mosque, one of the most famous mosques in Turkey.
