20 Lira Mustafa III

Mustafa III ruled from 1757 to 1774, a reign defined largely by the disastrous Russo-Turkish War that ended with the Treaty of Küçük Kaynarca — the first major territorial concession the Ottomans made to Russia, and a turning point the empire never fully recovered from. The Darphane has drawn on his reign repeatedly for commemorative issues, partly because his reforms of the Ottoman coinage system give the pairing a certain internal logic.
