- Yunker was a term for students of any military or junker school in between 1864 and 1917.
Junker schools in Russia were introduced in 1864. They were usually located next to district headquarters in a given region. Junker schools prepared low-rank military for officer rank. In 1900, the Russian government established junker infantry schools in Moscow and Kiev, and in 1902 a junker cavalry school in Yelizavetgrad. In 1901, the government transformed all former district junker schools into seven infantry schools (St.Petersburg, Vilna, Tiflis, Odessa, Kazan, Chuguyev, Irkutsk), one cavalry school (Tver) and three Cossack schools (Novocherkassk, Stavropol, Orenburg).
