Ministry of Internal Affairs (Ukraine)

The National Guard of Ukraine is the Ukrainian national gendarmerie and internal military force. It is part of the Ministry of Internal Affairs, responsible for public security. Originally created as an agency under the direct control of the Verkhovna Rada on 4 November 1991, following Ukrainian independence, it was later disbanded and merged into the Internal Troops of Ukraine in 2000 by then-President Leonid Kuchma as part of a "cost-saving" scheme. Following the 2014 Revolution of Dignity, amidst the Russian intervention, the National Guard was re-established, and the Internal Troops were disbanded.

A gendarmerie is a military force with law enforcement duties among the civilian population. The term gendarme is derived from the medieval French expression gens d'armes, which translates to "rural police" or "men-at-arms". In France and some Francophone nations, the gendarmerie is a branch of the armed forces that is responsible for internal security in parts of the territory, with additional duties as military police for the armed forces. It was introduced to several other Western European countries during the Napoleonic conquests. In the mid-twentieth century, a number of former French mandates and colonial possessions adopted a gendarmerie after independence. A similar concept exists in Eastern Europe in the form of Internal Troops, which are present in many countries of the former Soviet Union and its former allied countries.

Civil defense or civil protection is an effort to protect the citizens of a state from man-made and natural disasters. It uses the principles of emergency operations: prevention, mitigation, preparation, response, or emergency evacuation and recovery. Programs of this sort were initially discussed at least as early as the 1920s and were implemented in some countries during the 1930s as the threat of war and aerial bombardment grew. Civil-defense structures became widespread after authorities recognised the threats posed by nuclear weapons.

Customs is an authority or agency in a country responsible for collecting tariffs and for controlling the flow of goods, including animals, transports, personal effects, and hazardous items, into and out of a country. Traditionally, customs has been considered as the fiscal subject that charges customs duties and other taxes on import and export. In recent decades, the views on the functions of customs have considerably expanded and now covers three basic issues: taxation, security, and trade facilitation.

The militsiya in Ukraine was a type of domestic law enforcement agency (militsiya) from 1917 until 2015. The militsiya was originally formed while Ukraine was governed by the Ukrainian Soviet Socialist Republic, part of the Soviet Union, and it continued to serve as a national police service in post-Soviet Ukraine until it was replaced by the National Police of Ukraine on 7 November 2015. The militsiya was under the direct control of the Ministry of Internal Affairs, and it was widely seen as corrupt and inconsiderable to the demands of the Ukrainian public. During Euromaidan, the Militsiya was accused of brutality against protestors as well as kidnapping Automaidan activists, leading to the reputation of the Militsiya being irreversibly damaged. This resulted in its replacement under the post-Maidan Poroshenko presidency.

Russian is an East Slavic language mainly spoken in Russia. It is the native language of the Russians and belongs to the Indo-European language family. It is one of four living East Slavic languages, and is also a part of the larger Balto-Slavic languages. Besides Russia itself, Russian is an official language in Belarus, Kazakhstan, and Kyrgyzstan, and is used widely as a lingua franca throughout Ukraine, the Caucasus, Central Asia, and to some extent in the Baltic states. It was the de facto language of the former Soviet Union.

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.

Petro Oleksiyovych Poroshenko is a Ukrainian businessman and politician who served as the fifth president of Ukraine from 2014 to 2019. Poroshenko served as the Minister of Foreign Affairs from 2009 to 2010, and as the Minister of Trade and Economic Development in 2012. From 2007 until 2012, he headed the Council of Ukraine's National Bank. He was elected president on 25 May 2014, receiving 54.7% of the votes cast in the first round, thus winning outright and avoiding a run-off. During his presidency, Poroshenko led the country through the first phase of the war in Donbas, pushing the Russian separatist forces into the Donbas Region. He began the process of integration with the European Union by signing the European Union–Ukraine Association Agreement.
