Imperial anthems of the Ottoman Empire
The Ottoman Empire used anthems since its foundation in the late 13th century, but did not use a specific imperial or national anthem until the 19th century. During the reign of Mahmud II, when the military and imperial band were re-organized along Western European lines, Giuseppe Donizetti was invited to head the process.
