Defender of the Fatherland Day is a holiday observed in Russia, Turkmenistan, Belarus, Kyrgyzstan, Kazakhstan and Tajikistan.

The Donetsk–Krivoy Rog Soviet Republic or Donetsk–Kryvyi Rih Soviet Republic was a self-declared Soviet republic of the Russian SFSR proclaimed on 12 February 1918. It was founded three days after the government of the Ukrainian People's Republic (UPR) signed its Treaty of Brest-Litovsk with the Central Powers, which recognised the borders of the UPR. Lenin did not support the creation of the entity and neither did Sverdlov. Some other Bolsheviks like Elena Stasova, however, sent a telegraph of best wishes.

The Orange Revolution was a series of protests and political events that took place in Ukraine from late November 2004 to January 2005, in the immediate aftermath of the run-off vote of the 2004 Ukrainian presidential election, which was claimed to be marred by massive corruption, voter intimidation and electoral fraud. Kyiv, the Ukrainian capital, was the focal point of the movement's campaign of civil resistance, with thousands of protesters demonstrating daily. Nationwide, the revolution was highlighted by a series of acts of civil disobedience, sit-ins, and general strikes organized by the opposition movement.

The Titushky were mercenary agents in Ukraine who supported the Ukrainian security services during the administration of Viktor Yanukovych, often posing as street hooligans in sports clothing with the purpose of serving as provocateurs at pro-European and anti-Yanukovych political rallies that would incite violence in order to get protestors arrested. Their role grew more prominent in the wake of Euromaidan, where they were involved in numerous clashes and acts of violence during the movement.

Euromaidan, or the Maidan Uprising, was a wave of demonstrations and civil unrest in Ukraine, which began on 21 November 2013 with large protests in Maidan Nezalezhnosti in Kyiv. The protests were sparked by President Viktor Yanukovych's sudden decision not to sign the European Union–Ukraine Association Agreement, instead choosing closer ties to Russia and the Eurasian Economic Union. Ukraine's parliament had overwhelmingly approved of finalizing the Agreement with the EU, but Russia had put pressure on Ukraine to reject it. The scope of the protests widened, with calls for the resignation of Yanukovych and the Azarov government. Protesters opposed what they saw as widespread government corruption, abuse of power, human rights violations, and the influence of oligarchs. Transparency International named Yanukovych as the top example of corruption in the world. The violent dispersal of protesters on 30 November caused further anger. Euromaidan led to the 2014 Revolution of Dignity.

The Security Service of Ukraine or SBU is the law enforcement authority and main intelligence and security agency of the Ukrainian government, in the areas of counter-intelligence activity and combating organized crime and terrorism. The Constitution of Ukraine defines the SBU as a military formation, and its staff are considered military personnel with ranks. It is subordinated directly under the authority of the president of Ukraine. The SBU also operates its own special forces unit, the Alpha Group.

The National Bolshevik Party, also known as the Nazbols, operated from 1993 to 2007 as a Russian political party with a political program of National Bolshevism. The NBP became a prominent member of The Other Russia coalition of opposition parties. Russian courts banned the organization and it never officially registered as a political party. In 2010, its leader Eduard Limonov founded a new political party, called The Other Russia. There have been smaller NBP groups in other countries.
