The Russo–Ukrainian War is usually dated from February 2014, not from Russia’s full-scale invasion of 24 February 2022. Its roots, however, lie in the collapse of the Soviet Union, competing ideas about Ukraine’s sovereignty and geopolitical alignment, unresolved historical narratives, and Russia’s increasingly forceful effort to retain influence over former Soviet states. This summary follows Wikipedia’s accounts and reflects its use of both historical description and attributed scholarly interpretations. Russo–Ukrainian War
Ukraine became independent in 1991 when the Soviet Union dissolved. Its independence was confirmed by a referendum in December that year, in which a large majority voted for statehood, including majorities in every region. Russia also emerged from the USSR as an independent state and formally recognized Ukraine. Yet the two countries inherited unusually close and complicated connections: families, language, industry, Soviet institutions, energy networks, and military infrastructure were intertwined. Crimea hosted Russia’s Black Sea Fleet, while many Ukrainians spoke Russian as their first language or were bilingual. These facts did not erase Ukraine’s separate political identity, but they made the relationship unusually sensitive.
The post-Soviet settlement also produced a major security issue. Soviet nuclear weapons were located on Ukrainian territory after 1991. Ukraine ultimately agreed to relinquish them and accede to the Nuclear Non-Proliferation Treaty. In the 1994 Budapest Memorandum, Russia, the United Kingdom, and the United States gave Ukraine security assurances: they affirmed respect for its independence, sovereignty, and existing borders; pledged to refrain from threats or use of force against its territorial integrity or political independence; and committed to consultation if questions arose. The memorandum’s legal character has subsequently been debated, but politically it became central to Ukrainian arguments that Russia had broken assurances it had explicitly made. Budapest Memorandum
In the 1990s and early 2000s, Ukraine tried to balance relations with Russia and the West. It developed ties with the European Union and NATO while remaining economically dependent on Russia in important areas, particularly energy. This balancing strategy reflected domestic diversity as well. Political preferences did not map perfectly onto language or ethnicity, but western and central regions generally leaned more toward European integration, while some eastern and southern regions often showed greater support for close relations with Russia. Elections frequently turned on this divide, though Ukraine remained a unitary state with a shared national political system.
A major point of contention was NATO. After the Cold War, NATO admitted a number of central and eastern European states. Russia increasingly portrayed this expansion as a threat to its security and as evidence that Western powers had disregarded Russian interests. Ukraine’s relationship with NATO was uneven: at times Ukrainian leaders sought closer cooperation, while at other times they slowed or reversed that course. Russia’s position was that Ukraine’s NATO membership was unacceptable; Ukraine and many Western governments stressed the principle that sovereign states can choose their own security arrangements. The 1999 Charter for European Security, signed by Russia, affirmed each state’s right to choose or change such arrangements and to join alliances. Russo–Ukrainian War
The 2004 Orange Revolution sharpened the political stakes. A disputed presidential election initially declared Viktor Yanukovych the winner, but mass protests over fraud led to a rerun, won by the more pro-Western Viktor Yushchenko. The Orange Revolution demonstrated the ability of Ukrainian civic mobilization to affect national politics and was viewed by Russian leaders with suspicion. Russia saw “colour revolutions” in former Soviet countries not simply as domestic democratic uprisings but as Western-backed geopolitical shifts. Ukraine’s internal politics then remained unstable, with rivalry among pro-European leaders and periodic gains by Yanukovych and his Party of Regions.
In 2008, Ukraine and Georgia sought a clearer route toward NATO membership at the alliance’s Bucharest summit. NATO did not grant them Membership Action Plans, partly because several members feared provoking Russia, but declared that both countries would become members in the future. Russian President Vladimir Putin strongly opposed the prospect. Later that year, Russia fought a war with Georgia and took effective control of the breakaway territories of Abkhazia and South Ossetia. Wikipedia notes that scholars have treated this conflict and the Western response to it as part of the context in which Russia assessed the risks of using force in its neighbourhood. Russo–Ukrainian War
Yanukovych won Ukraine’s presidency in 2010. His government pursued closer relations with Russia and extended Russia’s lease for the Black Sea Fleet base at Sevastopol in Crimea. At the same time, Ukraine continued negotiating an Association Agreement with the European Union, including a deep free-trade arrangement. The agreement became more than a trade issue: it symbolised a choice between deeper integration with the EU and a Russian-led economic and political sphere.
In 2013, Ukraine’s parliament broadly supported finalising the EU agreement. The Kremlin pressured Kyiv to abandon it, imposing restrictions on Ukrainian imports and signalling that further economic consequences could follow. A Russian presidential adviser, Sergey Glazyev, warned that Russia might no longer recognize Ukraine’s borders if the agreement were signed. In November 2013, Yanukovych abruptly suspended preparations for signing the EU agreement. This decision triggered protests in Kyiv that became known as Euromaidan. Russo–Ukrainian War
Euromaidan began as a pro-European protest but broadened into a movement against corruption, police violence, and Yanukovych’s concentration of power. Demonstrators occupied Kyiv’s Maidan Nezalezhnosti, or Independence Square. The government’s violent dispersal of protesters increased support for the movement. New anti-protest laws in January 2014 intensified the crisis. After deadly confrontations in February, Yanukovych fled Kyiv; parliament voted that he had withdrawn from performing his duties and set an early presidential election. Ukrainians who supported the uprising call it the Revolution of Dignity. Russia characterized it as an unconstitutional coup, and this competing interpretation became a core part of the Russian justification for subsequent actions. Euromaidan
The political vacuum after Yanukovych’s departure was followed by unrest in Crimea and eastern Ukraine. Crimea was particularly significant. It had been part of the Russian Empire from 1783, had a Russian-majority population by 2014, and was home to the Black Sea Fleet. It was transferred administratively from the Russian Soviet republic to the Ukrainian Soviet republic in 1954, when both were within the USSR. After Ukrainian independence, Crimea remained part of Ukraine as an autonomous republic; Sevastopol had special status. Crimea was also the homeland of the Crimean Tatars, who had been deported en masse by Stalin in 1944 and whose leaders largely opposed Russian intervention in 2014. 2014 Russian Annexation of Crimea
In late February 2014, armed men in unmarked uniforms seized key sites in Crimea, including the regional parliament and airports. Russia initially denied that these were Russian forces, though Putin later acknowledged their role. Under armed control, Crimea’s parliament replaced the regional government and set a referendum. The vote was held on 16 March, during Russian military occupation, and did not include an option to retain the existing constitutional arrangement. Russian-installed authorities reported overwhelming support for joining Russia. Crimea declared independence and Russia formally incorporated Crimea and Sevastopol on 18 March. Russian Occupation of Crimea
Ukraine, the United Nations General Assembly, and most states regarded this as an illegal annexation and continued to regard Crimea as Ukrainian territory under Russian occupation. Russia described it as reunification and appealed to self-determination, arguing that the referendum reflected local will. The international disagreement was therefore not merely semantic: it concerned the validity of a territorial change carried out in the presence of foreign forces and contrary to Ukraine’s constitutional procedures. The annexation prompted sanctions against Russia and ended the assumption that borders in post-Cold War Europe would not be altered by force. 2014 Russian Annexation of Crimea
At the same time, pro-Russian and anti-government protests emerged in several eastern and southern Ukrainian cities. The most consequential took place in the Donbas, the industrial region comprising Donetsk and Luhansk oblasts. There were genuine local grievances: distrust of the new authorities in Kyiv, concern among Russian-speaking residents, economic anxiety, and resentment at the proposed—though never enacted—repeal of the law granting Russian a regional-language status. Russian media amplified claims that a “fascist junta” had seized power in Kyiv and that Russian speakers faced imminent danger.
Wikipedia’s account also emphasizes Russian intervention in transforming unrest into armed conflict. Russian-linked operatives, funding, propaganda, weapons, and personnel supported separatist forces. In April 2014, armed men led by Russian citizen Igor Girkin seized Sloviansk and other locations. The self-proclaimed Donetsk People’s Republic and Luhansk People’s Republic declared independence. Ukraine responded with an “Anti-Terrorist Operation” to restore state control. This became the War in Donbas. War in Donbas
Russia’s role in Donbas was initially presented as indirect: Moscow spoke of volunteers and local self-defence forces. Yet the conflict involved Russian weaponry, advisers, fighters, and eventually regular Russian troops. Wikipedia describes separatist structures as largely under Russian control and states that Russia covertly supported them militarily. Russia has denied key allegations of direct military involvement, while later acknowledging the presence of military specialists and treating separatist combatants as Russian veterans. The ambiguity was part of what was often called “hybrid warfare”: conventional military pressure combined with irregular fighters, political action, economic leverage, cyber activity, and information warfare. War in Donbas
By summer 2014, Ukrainian forces had regained significant ground. Russia then sent more substantial military support across the border, helping separatist forces reverse Ukrainian advances. Major battles followed, including around Ilovaisk in 2014 and Debaltseve in 2015. Malaysia Airlines Flight 17 was shot down over separatist-held territory in July 2014, killing all 298 people aboard; international investigations concluded that a Buk missile system brought from Russia was used. The incident made the conflict a global issue and increased pressure on Russia. War in Donbas
Peace efforts produced the Minsk Protocol in September 2014 and the more detailed Minsk II agreement in February 2015, negotiated with French and German mediation in the Normandy format and overseen by the Organization for Security and Co-operation in Europe. The agreements called for ceasefires, withdrawal of heavy weapons, prisoner exchanges, local elections, and a special status for parts of Donetsk and Luhansk. They reduced but did not end fighting. Each side accused the other of violations and disagreed over sequencing: Ukraine sought security, a ceasefire, and restoration of border control before political concessions, while Russia and the separatists emphasised political arrangements and special status first. Minsk Agreements
From 2015 to 2021, the war was often described as “frozen,” but it was not truly dormant. Fighting continued along a heavily militarised line of contact, people were killed, and Russia-controlled separatist administrations consolidated control over parts of Donetsk and Luhansk. The conflict also reshaped Ukrainian politics. Rather than pulling Ukraine back into Russia’s orbit, the 2014 events strengthened Ukrainian civic identity, increased support for European integration, and deepened hostility toward the Russian state. Ukraine later made EU and NATO aspirations constitutional objectives, while Russia continued to cite NATO expansion and alleged mistreatment of Russian speakers as security concerns.
The wider dispute involved incompatible views of sovereignty and regional order. A common Russian narrative held that Russia had legitimate security interests and a sphere of influence in former Soviet territory; that NATO’s enlargement created an unacceptable threat; and that Ukraine’s post-2014 government was installed through a Western-backed coup. Ukraine and its supporters argued that Ukraine was entitled to determine its own government and alliances, that Russia had violated internationally recognized borders and commitments, and that NATO interest was in large part a response to Russian conduct. Wikipedia attributes to political scientist Paul D’Anieri four overlapping motives behind Russia’s war: a desire to regain control of Ukraine, a great-power claim to a sphere of influence, a European security dilemma around NATO, and concern in authoritarian Russia that a democratic Ukraine might be politically threatening. Russo–Ukrainian War
The immediate prelude to the 2022 invasion began with major Russian troop build-ups near Ukraine in spring 2021 and again from autumn 2021, including in Belarus. Russia repeatedly said the deployments were exercises and denied plans to invade. At the same time, Moscow issued sweeping demands to the United States and NATO, including guarantees that Ukraine would never join NATO and that NATO would reduce its military posture in Eastern Europe. These demands were rejected, particularly because they would have constrained the choices of states not party to a Russia–NATO bargain. Russo–Ukrainian War (2022–present)
Putin’s public rhetoric also became more expansive. In a July 2021 essay, he argued that Russians and Ukrainians were historically “one people” and questioned the legitimacy of a separate Ukrainian national identity and statehood. In February 2022, Russia recognized the self-proclaimed Donetsk and Luhansk republics as independent and sent forces into their territories. On 24 February, Putin announced what he called a “special military operation,” claiming objectives of “demilitarising” and “denazifying” Ukraine and alleging genocide in Donbas. Wikipedia notes that the genocide claim lacked evidence and that Putin’s assertions about Ukraine’s government formed part of the invasion’s stated rationale. Russo–Ukrainian War (2022–present)
Russia then launched a full-scale invasion from Belarus, Russia, occupied Crimea, and the Donbas. This was not a new war beginning from nothing, but a dramatic escalation of the conflict that began in 2014. In short, the background combines post-Soviet state-building, contested security arrangements, Ukrainian domestic political change, Russian imperial and security narratives, the seizure of Crimea, the unresolved Donbas war, and the collapse of the Minsk process. The result was a conflict in which both historical memory and immediate strategic decisions mattered—but in which the decisive military escalations were Russia’s occupation and annexation of Crimea in 2014 and its full-scale invasion in 2022.
