2022 – Russo-Ukrainian War: Days after recognizing Donetsk and Luhansk as independent states, Russian president Vladimir Putin orders the 2022 Russian invasion of Ukraine. The Russo-Ukrainian war began in February 2014 and is ongoing. Following Ukraine's Revolution of Dignity, Russia occupied Crimea and annexed it from Ukraine. It then supported Russian separatist armed groups who started a war in the eastern Donbas region against Ukraine's military. In 2018, Ukraine declared the region to be occupied by Russia. On 24 February 2022, Putin announced a "special military operation" to "demilitarize and denazify" Ukraine, claiming Russia had no plans to occupy the country. The Russian invasion that followed was internationally condemned; many countries imposed sanctions against Russia, and sent humanitarian and military aid to Ukraine. In the face of fierce resistance, Russia abandoned an attempt to seize Kyiv in early April. In August, Ukrainian forces began liberating territories in the north-east and south. In September, Russia declared the annexation of four partially occupied provinces, which was internationally condemned. Since then, Russian offensives and Ukrainian counteroffensives have gained only small amounts of territory. The invasion has also led to attacks in Russia by Ukrainian and Ukrainian-backed forces, among them a cross-border offensive into Russia's Kursk region in August 2024. Russia has repeatedly carried out deliberate and indiscriminate attacks on civilians far from the frontline. The UN Human Rights Office reported that Russia was committing severe human rights violations in occupied Ukraine. The ICC opened an investigation into war crimes and issued arrest warrants for Putin and several other Russian officials. Russia has repeatedly refused calls for a ceasefire. The first eight years of conflict also involved naval incidents and cyberwarfare. In February 2022, Russia launched a full-scale invasion of Ukraine and began occupying more of the country, starting the current phase of the war, the biggest conflict in Europe since World War II. The war has resulted in a refugee crisis and hundreds of thousands of deaths.
