In later centuries, Russian Tsars would declare a state of emergency and use death squad tactics in order to suppress domestic uprisings like Pugachev's Rebellion and the Russian Revolution of 1905. During the latter, Tsar Nicholas II of Russia ordered the Imperial Russian Army to ally itself with the Black Hundreds, an ultra-nationalist paramilitary group. Those captured in arms against the Tsar's forces were tried by military tribunals before being hanged or shot. According to Simon Sebag Montefiore, being caught wearing similar clothing to Anti-Tsarist militias was often enough for court martial followed by execution. These tactics were continued by the anti-communist White Movement during the Russian Civil War (1917-1920).
