The Persian Cossack Brigade was an elite cavalry unit formed in 1879 in Persia (modern Iran). During much of their history they were the only functional, effective military unit of the Qajar Dynasty. Acting on occasion as kingmakers, this force played a pivotal role in modern Persian history during the Revolution of 1905–1911, the rise of Reza Shah and the formation of the Pahlavi Dynasty.
