Osman Nuri Pasha, also known as Gazi Osman Pasha, was an Ottoman Turkish field marshal. Being one of the most respected and decorated Ottoman pashas of all time, many songs have been written for him, and many places named after him. This is mainly because he held the Bulgarian town of Plevna for five months against superior Russo-Romanian forces in 1877 during the Russo-Turkish War, though the city eventually fell.
