It is believed that individual instrumentalists may have been mentioned in the 8th century Orkhon inscriptions, the oldest written sources of the people who are ancestors of modern Turks. Such military bands as the mehters, however, were not definitively mentioned until the 13th century. It is believed that the first "mehter" was sent to Osman Gazi by the Seljuk Sultan Alaeddin III as a present along with a letter that salutes the newly formed state. From then on every day after the afternoon prayer; "mehter" played for the Ottoman ruler. The notion of a military marching band, such as those in use even today, began to be borrowed from the Ottoman Empire in the 16th century.
The sound associated with the mehterân also exercised an influence on European classical music, with composers such as Joseph Haydn, Wolfgang Amadeus Mozart, and Ludwig van Beethoven all writing compositions inspired by or designed to imitate the music of the mehters.
