Vladimir Vladimirovich Putin is a Russian politician and former intelligence officer who is the president of Russia. Putin has held continuous positions as president or prime minister since 1999: as prime minister from 1999 to 2000 and from 2008 to 2012, and as president from 2000 to 2008 and since 2012. He is the longest-serving Russian or Soviet leader since Joseph Stalin.
Sevastopol, sometimes written Sebastopol, is the largest city in Crimea and a major port on the Black Sea. Due to its strategic location and the navigability of the city's harbours, Sevastopol has been an important port and naval base throughout its history. Since the city's founding in 1783 it has been a major base for Russia's Black Sea Fleet. During the Cold War of the 20th century, it was a closed city. The total administrative area is 864 square kilometres (334 sq mi) and includes a significant amount of rural land. The urban population, largely concentrated around Sevastopol Bay, is 479,394, and the total population is 547,820.
The Ukrainian Navy is the maritime forces of Ukraine and one of the five branches of the Armed Forces of Ukraine.
There are currently no diplomatic or bilateral relations between Russia and Ukraine. The two states have been at war since Russia invaded the Crimean peninsula in February 2014, and Russian-controlled armed groups seized Donbas government buildings in May 2014. Following the Ukrainian Euromaidan in 2014, Ukraine's Crimean peninsula was occupied by unmarked Russian forces, and later illegally annexed by Russia, while pro-Russia separatists simultaneously engaged the Ukrainian military in an armed conflict for control over eastern Ukraine; these events marked the beginning of the Russo-Ukrainian War. In a major escalation of the conflict on 24 February 2022, Russia launched a large scale military invasion across a broad front, causing Ukraine to sever all formal diplomatic ties with Russia.
The Revolution of Dignity, also known as the Maidan Revolution or the Ukrainian Revolution, took place in Ukraine in February 2014 at the end of the Euromaidan protests, when deadly clashes between protesters and state forces in the capital Kyiv culminated in the ousting of elected President Viktor Yanukovych, the return to the 2004 Constitution of Ukraine, and the outbreak of the 2014 Russo-Ukrainian War.
The Russo-Ukrainian War is an ongoing war between Russia and Ukraine, which began in February 2014. Following Ukraine's Revolution of Dignity, Russia occupied and annexed Crimea from Ukraine and supported pro-Russian separatists fighting the Ukrainian military in the Donbas war. The first eight years of conflict also included naval incidents, cyberwarfare, and heightened political tensions. In February 2022, Russia launched a full-scale invasion of Ukraine and began occupying more of the country.
From the end of February 2014, in the aftermath of the Euromaidan and the Revolution of Dignity, which resulted in the ousting of Russian-leaning Ukrainian President Viktor Yanukovych, demonstrations by Russian-backed, pro-Russian, and anti-government groups took place in major cities across the eastern and southern regions of Ukraine. The unrest, which was supported by Russian military and intelligence, belongs to the early stages of the Russo-Ukrainian War.
The annexation of Crimea by the Russian Federation took place in the aftermath of the 2014 Ukrainian revolution. On 22–23 February, Russian President Vladimir Putin convened an all-night meeting with security services chiefs to discuss pullout of deposed President, Viktor Yanukovych, and at the end of that meeting Putin remarked that "we must start working on returning Crimea to Russia.". Russia sent in soldiers on February 27, 2014. Crimea held a referendum. According to official Russian and Crimean sources 95% voted to reunite with Russia. The legitimacy of the referendum has been questioned by the international community on both legal and procedural grounds.
In February and March 2014, Russia invaded the Crimean Peninsula, part of Ukraine, and then annexed it. This took place in the relative power vacuum immediately following the Revolution of Dignity. It marked the beginning of the Russo-Ukrainian War.
The war in Donbas, or Donbas war, was a phase of the Russo-Ukrainian War in the Donbas region of Ukraine. The war began 12 April 2014, when a fifty-man commando unit headed by Russian citizen Igor Girkin seized Sloviansk in Donetsk oblast. The Ukrainian military launched an operation against them. It continued until it was subsumed by the Russian invasion of Ukraine in February 2022.
The Armed Forces of Ukraine 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 after Ukrainian independence in 1991.
The siege of Southern Naval Base lasted from 3 March 2014 until its definitive capture on 27 March 2014. The action began with the blockade of Donuzlav bay by the Russian missile cruiser Moskva. The Russian Navy later scuttled the Russian anti-submarine ship Ochakov and several smaller vessels in the mouth of the bay to prevent Ukrainian ships from sailing to open sea and reaching the Ukrainian fleet in Odesa. As a result, 13 Ukrainian ships were bottled up and eventually captured by Russia in Donuzlav bay. The blockade ended when the Russian Navy seized the last ship under the Ukrainian flag in Crimea, the minesweeper Cherkasy.
Casualties in the Russo-Ukrainian War included six deaths during the 2014 annexation of Crimea by the Russian Federation, 14,200–14,400 military and civilian deaths during the War in Donbas, and up to 500,000 estimated casualties during the 2022 Russian invasion of Ukraine.
On 24 February 2022, Russia invaded Ukraine in an escalation of the Russo-Ukrainian War that started in 2014. The invasion became the largest attack on a European country since World War II. It is estimated to have caused tens of thousands of Ukrainian civilian casualties and hundreds of thousands of military casualties. By June 2022, Russian troops occupied about 20% of Ukrainian territory. From a population of 41 million in January 2022, about 8 million Ukrainians had been internally displaced and more than 8.2 million had fled the country by April 2023, creating Europe's largest refugee crisis since World War II. Extensive environmental damage caused by the war, widely described as an ecocide, contributed to food crises worldwide.
On 27 February 2014, unmarked Russian soldiers were deployed to the Crimean Peninsula in order to wrest control of it from Ukraine, triggering the Russo-Ukrainian War. This military occupation, which the Ukrainian government considers to have begun on 20 February, laid the foundation for the Russian annexation of Crimea on 18 March 2014. Under Russia, the Ukrainian Autonomous Republic of Crimea was replaced by the Republic of Crimea, though the legitimacy of the latter is scarcely recognized internationally.
Beginning in July 2022, a series of explosions and fires occurred on the Russian-occupied Crimean Peninsula from where the Russian Army had launched its offensive on Southern Ukraine during the Russian invasion of Ukraine. Occupied since 2014, Crimea was a base for the subsequent Russian occupation of Kherson Oblast and Russian occupation of Zaporizhzhia Oblast. The Ukrainian government has not accepted responsibility for all of the attacks.
