Russo-Ukrainian war (2022–present)
Largest war in Europe since World War II.
The Russo-Ukrainian war, which began in its current phase on 24 February 2022, represents the largest and deadliest conflict in Europe since World War II. It is a major escalation of the ongoing war between the two countries that started with Russia's initial attack on Ukraine in 2014. The fighting has resulted in hundreds of thousands of military casualties on both sides and tens of thousands of civilian deaths in Ukraine. Out of a pre-war population of 41 million, approximately 8 million Ukrainians have been internally displaced, and between 6 and 7 million have fled the country, producing Europe's largest refugee crisis since the 1940s.
In late 2021, Russia amassed troops along Ukraine's borders and presented demands to the West, including a permanent ban on Ukraine joining NATO. Despite repeatedly denying plans for an invasion, Russian President Vladimir Putin announced a "special military operation" on 24 February 2022, claiming it aimed to support the Russian-backed breakaway republics of Donetsk and Luhansk, which had been fighting Ukrainian forces in the Donbas since 2014. Putin expressed irredentist and imperialist views, questioning Ukraine's legitimacy as a state, and baselessly accused the Ukrainian government of being neo-Nazis committing genocide against Russian speakers. He stated Russia's goal was to "demilitarise and denazify" Ukraine. Russian forces launched air strikes and a ground invasion along three axes: from Belarus toward Kyiv in the north, from occupied Crimea in the south, and from the Donbas toward Kharkiv in the east. Ukraine responded by declaring martial law, ordering a general mobilisation, and cutting diplomatic ties with Russia.
By April 2022, Russian troops had withdrawn from the northern front and the outskirts of Kyiv after facing stiff resistance and logistical problems. The Bucha massacre was discovered following their retreat. Russia then shifted its offensive to the Donbas, capturing Mariupol after a destructive siege. Throughout the war, Russia has continued to bomb both military and civilian targets far from the front lines, including striking Ukraine's energy grid during winter. In late 2022, Ukraine launched successful counteroffensives in the south and east, liberating most of Kharkiv Oblast. Russia subsequently illegally annexed four partially occupied provinces. In November, Ukraine recaptured the city of Khe

Lore & Background
The Russo-Ukrainian war, which escalated dramatically in 2022, is the largest and deadliest conflict in Europe since World War II. It began when Russia launched a full-scale invasion of Ukraine on 24 February 2022, following months of troop massing near Ukraine’s borders and demands that Ukraine never join NATO. Russian President Vladimir Putin announced a “special military operation,” claiming it aimed to support the Russian-backed breakaway republics of Donetsk and Luhansk, which had been fighting Ukraine since 2014. He espoused irredentist views, asserting without evidence that Ukraine was a neo-Nazi state committing genocide against its Russian minority, and stated the goal was to “demilitarise and denazify” the country. The invasion proceeded on three fronts: a northern front from Belarus toward Kyiv, a southern front from occupied Crimea, and an eastern front from the Donbas toward Kharkiv. Ukraine responded by imposing martial law, ordering a general mobilisation, and severing diplomatic relations with Russia. After stiff resistance and logistical problems, Russian forces withdrew from the north and outskirts of Kyiv by April 2022, revealing the Bucha massacre. Russia then captured Mariupol after a destructive siege and continued bombing military and civilian targets, including Ukraine’s energy grid. In late 2022, Ukraine launched successful counteroffensives, liberating most of Kharkiv Oblast and the city of Kherson. By mid-2024, after steady Russian advances in the east, Ukraine launched a cross-border offensive into Russia’s Kursk Oblast, where North Korean soldiers were deployed to aid Russia. The war has caused hundreds of thousands of military casualties and tens of thousands of Ukrainian civilian deaths. From a population of 41 million, about 8 million Ukrainians were internally displaced and 6–7 million fled the country, creating Europe’s largest refugee crisis since World War II. The United Nations has documented severe human rights violations in occupied areas, and Russia’s policies have led to allegations of genocide. The International Criminal Court opened an investigation into crimes against humanity, war crimes, and genocide, issuing arrest warrants for Putin and other officials. The conflict has also disrupted global food supplies and caused widespread environmental damage described as ecocide. Peace negotiations remain stalled, with Ru
