Ahmed I - online puzzles
Ahmed I ( Ottoman Turkish: احمد اول Aḥmed-i evvel; Turkish: I. Ahmed; 18 April 1590 – 22 November 1617) was the Sultan of the Ottoman Empire from 1603 until his death in 1617. Ahmed's reign is noteworthy for marking the end of the Ottoman tradition of royal fratricide; henceforth Ottoman rulers would no longer 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.
