Mustafa Shokay, born into an aristocratic family in the village Aulie-Tarangyl in the Kyzyl-Orda region and of Kipchak and Kazakh origin, was one of the leaders of a revolt in 1917 against the Bolsheviks . After the revolt was crushed, he fled the country and lived in exile in Europe. During this time, he became one of the leading authorities on the history of Central Asia and was an ardent Turkestani nationalist. He later went on to help form the Turkestan Legion, who allied themselves with Germany during the Second World War, hoping to establish an independent state in Central Asia.
Mustafa is played by Aziz Beyshenaliev.
Anyway, (at least according to this clip) he also had a very dramatic love story with his wife, a Jewish redhead called Maria Yakovlevna ...
The music is by the duo Musicola. The singer, Karina Abdullina, apparently also plays the role of Shokay's wife.
My favourite scene:
Here are some more screencaps from this film, and here's a bit more about Musicola.
Apparently, Shokay is buried here in Berlin.
