President of Ukraine in the context of "Constitution of Ukraine"

A commander-in-chief or supreme commander (supreme commander-in-chief) is the person who exercises supreme command and control over an armed force or a military branch. As a technical term, it refers to military competencies that reside in a country's executive leadership, a head of state, head of government, or other designated government official.

While often used interchangeably, the title of Supreme Commander–in–Chief is technically different, since the two titles can be in use simultaneously. For example, in the case of the Armed Forces of Ukraine, the supreme commander-in-chief is the president of Ukraine, while the commander-in-chief is its professional head.

The Armed Forces of Ukraine (AFU) are the military forces of Ukraine. All military and security forces, including the Armed Forces, are under the command of the president of Ukraine and subject to oversight by a permanent Verkhovna Rada parliamentary commission. They trace their lineage to 1917, while the modern armed forces were formed again in 1991. The Armed Forces of Ukraine are the fifth largest armed force in the world in terms of both active personnel as well as total number of personnel with the eighth largest (14th largest) defence budget in the world, and it also operates one of the largest and most diverse drone fleets in the world. Due to the ongoing Russo-Ukrainian War, the Ukrainian Armed Forces has been described as "the most battle-hardened in Europe," but has suffered many casualties.

Ukraine's armed forces are composed of the Ground Forces, the Air Force, the Navy, the Air Assault Forces, the Marine Corps, the Special Operations Forces, the Unmanned Systems Forces, and the Territorial Defense Forces. Ukraine's navy includes its own Naval Aviation. The Sea Guard is the coast guard service of Ukraine, and it is organized as part of the Border Guard Service, not subordinate to the navy. The National Guard serves as a paramilitary reserve component of the Armed Forces.

The Commander-in-Chief of the Armed Forces of Ukraine (Ukrainian: Головнокомандувач Збройних сил України, romanized: Holovnokomanduvach Zbroinykh syl Ukrayiny) is the professional head of the Armed Forces of Ukraine. The position was created by President Volodymyr Zelenskyy on 28 March 2020, before which the Chief of the General Staff was the commander-in-chief.

The Revolution of Dignity (Ukrainian: Революція гідності, romanized: Revoliutsiia hidnosti), also known as the Maidan Revolution or the Ukrainian Revolution, took place in Ukraine in February 2014 at the end of the Euromaidan protests. Scores of protesters were killed by government forces during clashes in the capital Kyiv. Parliament then voted to remove President Viktor Yanukovych, return to the 2004 Constitution of Ukraine, and call new elections. The revolution prompted Russia to occupy Crimea, starting the Russo-Ukrainian War.

In November 2013, a wave of large-scale protests known as "Euromaidan" began in response to President Yanukovych's sudden decision not to sign a political association and free trade agreement with the European Union (EU), instead choosing closer ties to Russia. Euromaidan soon developed into the largest democratic mass movement in Europe since 1989. The Verkhovna Rada (Ukrainian parliament) had overwhelmingly approved finalizing the EU association agreement; Russia had pressured 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 and abuse of power, the influence of Russia and oligarchs, police brutality, human rights violations, and repressive anti-protest laws.

Viktor Fedorovych Yanukovych (born 9 July 1950) is a former Ukrainian politician who served as the fourth president of Ukraine from 2010 to 2014. He also served as the prime minister of Ukraine several times between 2002 and 2007 and was a member of the Verkhovna Rada (parliament) from 2006 to 2010. Yanukovych was removed from the presidency during the 2014 Revolution of Dignity, which followed months of protests against him. Since then, he has lived in exile in Russia.

Yanukovych was a member of the pro-Russian Party of Regions. Before entering national politics, Yanukovych was the governor of his native Donetsk Oblast from 1997 to 2002. He was simultaneously the chairman of the oblast's legislature from 1999 to 2001. He first ran for president in the 2004 election, where he was declared the winner against Viktor Yushchenko. However, allegations of electoral fraud and voter intimidation caused widespread protests, in what became known as the Orange Revolution. The Ukrainian Supreme Court nullified the election and ordered a rerun, which Yanukovych lost to Yushchenko. Yanukovych ran for president again in 2010, this time beating Yulia Tymoshenko in an election deemed free and fair by international observers.

The State Border Guard Service of Ukraine (abbr. SBGSU; Ukrainian: Державна Прикордонна Служба України, romanized: Derzhavna Prykordonna Sluzhba Ukrainy, pronounced [derˈʒɑu̯nɐ prɪkorˈdɔnːɐ ˈsluʒbɐ ʊkrɐˈjinɪ]; abbr. ДПСУ, DPSU) is the border guard of Ukraine. It is an independent law enforcement agency, organized by the Constitution of Ukraine as a military formation, the head of which is subordinated to the President of Ukraine.

The Service was created on July 31, 2003, after the reorganization of the State Committee for Protection of the State Border. During wartime, units of the State Border Guard Service fall under the command of the Armed Forces of Ukraine. The State Border Guard Service includes the Ukrainian Sea Guard, which is the country's coast guard. It is also responsible for running Temporary Detention Centres, in which refugees are held.

The Council of Ministers of the Autonomous Republic of Crimea (Ukrainian: Рада міністрів Автономної Республіки Крим; Russian: Совет министров Автономной Республики Крым), briefly SovMin, is the executive branch of government of the Autonomous Republic of Crimea, a republic within southern Ukraine that is currently suspended due to Russian occupation of the Crimean Peninsula since February 27, 2014. The Council of Ministers derived its authority from the Constitution and laws of Ukraine and normative acts of the Verkhovna Rada of Crimea which bring them into its competency.

The Chairman, who is appointed by the Verkhovna Rada (parliament) with approval of the President of Ukraine, headed the cabinet.
