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.
Relations between Ukraine and the North Atlantic Treaty Organization (NATO) started in 1991 following Ukraine's independence after the dissolution of the Soviet Union. Ukraine-NATO ties gradually strengthened during the 1990s and 2000s, and Ukraine aimed to eventually join the alliance. Although co-operating with NATO, Ukraine remained a neutral country. After it was attacked by Russia in 2014, Ukraine has increasingly sought NATO membership.
The Russo-Ukrainian War 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. These first eight years of conflict also included naval incidents and cyberwarfare. In February 2022, Russia launched a full-scale invasion of Ukraine and began occupying more of the country, starting the biggest conflict in Europe since World War II. The war has resulted in a refugee crisis and tens of thousands of deaths.
The war in Donbas, also known as the Donbas war, was a phase of the Russo-Ukrainian War in the Donbas region of Ukraine. The war began in April 2014, when a commando unit headed by Russian citizen Igor Girkin seized Sloviansk in Donetsk oblast. The Ukrainian military launched an operation against them. The war continued until subsumed by the Russian invasion of Ukraine in 2022.
The "little green men" were Russian soldiers who were masked and wore unmarked uniforms upon the outbreak of the Russo-Ukrainian War in 2014. They were active just before and during the Russian annexation of Crimea and carried regular weapons and equipment, but were always masked and wore distinctly unmarked green military fatigues. Russia, which had been denying any involvement in Ukraine prior to the annexation, used these little green men to give it plausible deniability on the international stage.
Many states and international organisations reacted to the war in Donbas, a phase of the Russo-Ukrainian War that took place from 2014 to 2022 in the Donbas historical region in eastern Ukraine.
The Russian-occupied territories of Ukraine are areas of southern and eastern Ukraine that are controlled by Russia as a result of the Russo-Ukrainian War and the ongoing invasion. In Ukrainian law, they are defined as the "temporarily occupied territories". As of 2024, Russia occupies almost 20% of Ukraine and about 3 to 3.5 million Ukrainians are estimated to be living under occupation; since the invasion, the occupied territories lost roughly half of their population. The United Nations Human Rights Office reports that Russia is committing severe human rights violations in occupied Ukraine, including arbitrary detentions, enforced disappearances, torture, crackdown on peaceful protest and freedom of speech, enforced Russification, passportization, indoctrination of children, and suppression of Ukrainian language and culture.
In March and April 2021, prior to the 2022 Russian invasion of Ukraine, the Russian Armed Forces began massing thousands of personnel and military equipment near Russia's border with Ukraine and in Crimea, representing the largest mobilisation since the illegal annexation of Crimea in 2014. This precipitated an international crisis due to concerns over a potential invasion. Satellite imagery showed movements of armour, missiles, and heavy weaponry towards the border. The troops were partially withdrawn by June 2021, though the infrastructure was left in place. A second build-up began in October 2021, this time with more soldiers and with deployments on new fronts; by December over 100,000 Russian troops were massed around Ukraine on three sides, including Belarus from the north and Crimea from the south. Despite the Russian military build-ups, Russian officials from November 2021 to 20 February 2022 repeatedly denied that Russia had plans to invade Ukraine.
Many states, international organizations, and civil society actors worldwide had expressed their reactions to the then-escalating crisis between Russia and Ukraine that started in March 2021. The crisis eventually culminated in a Russian invasion of Ukraine, beginning on 24 February 2022.
As part of the Russian invasion of Ukraine, the Russian state and state-controlled media have spread disinformation in their information war against Ukraine. Ukrainian media and politicians have also been accused of using propaganda and deception, although such efforts have been described as more limited than the Russian disinformation campaign.
On 24 February 2022, Russia invaded Ukraine in a major escalation of the Russo-Ukrainian War, which started in 2014. The invasion, the largest and deadliest conflict in Europe since World War II, has caused hundreds of thousands of military casualties and tens of thousands of Ukrainian civilian casualties. As of 2024, Russian troops occupy about 20% of Ukraine. From a population of 41 million, 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.
The Russian invasion of Ukraine received widespread international condemnation, leading to new sanctions being imposed on Russia, which triggered a Russian financial crisis. Reactions among governments have most often been negative, with criticism and condemnation, particularly in Europe, the Americas, and Southeast Asia.
"On conducting a special military operation" was a televised broadcast by Russian president Vladimir Putin on 24 February 2022, announcing the Russian invasion of Ukraine.
There have been several rounds of peace talks to halt the Russian invasion of Ukraine (2022–present) and end the Russo-Ukrainian War (2014–present). The first meeting was held four days after the start of the invasion, on 28 February 2022, in Belarus. It concluded without result. A second and third round of talks took place on 3 and 7 March 2022 on the Belarus–Ukraine border. A fourth and fifth round of talks were held on 10 and 14 March in Antalya, Turkey.
"Address concerning the events in Ukraine" was a televised address by Russian President Vladimir Putin on 21 February 2022, announcing that the Russian government would recognise the Ukrainian separatist regions of the Donetsk People's Republic and the Luhansk People's Republic as independent. During the speech, Putin also made a number of claims regarding Ukrainian history and Ukrainian domestic politics. Genocide experts, historians and other experts have shown these claims to be false and possibly justifying a genocide. The speech, which marked a significant escalation in the culminating Russo-Ukrainian crisis, was followed three days later by another speech declaring "a special military operation" in Ukraine—announcing the Russian invasion of Ukraine.
The Zeitenwende speech was an address delivered to the Bundestag by Olaf Scholz, the Chancellor of Germany, on 27 February 2022. His speech was a reaction to the Russian invasion of Ukraine on 24 February. Scholz described the attack as a "historic turning point" and announced that in response his government would use a €100 billion fund to significantly increase military spending, reversing Germany's previously cautious defence policy.
On 30 September 2022, Russia, amid an ongoing invasion of Ukraine, unilaterally declared its annexation of areas in and around four Ukrainian oblasts—Donetsk, Kherson, Luhansk, and Zaporizhzhia. Most of Luhansk Oblast and part of Donetsk Oblast had been controlled by pro-Russian separatists since 2014, while the Kherson and Zaporizhzhia Oblasts were invaded by Russia in 2022. The boundaries of the areas to be annexed and their borders were not defined; Russian officials stated that they would be defined later. None of the oblasts were fully under Russian control at the time of the declaration, nor since. If limited to the areas then under Russian control the annexation would still be the largest in Europe since World War II.
This timeline of the Russian invasion of Ukraine covers the period from 24 February 2022, when Russia launched a military invasion of Ukraine, to 7 April 2022 when fighting focused away from the north and towards the south and east of Ukraine.
This timeline of the prelude to the Russian invasion of Ukraine covers a period of heightened tensions between Russia and Ukraine from early 2021 until the start of the Russian invasion of Ukraine on 24 February 2022.
