Minsk agreements in the context of "Russo-Ukrainian war"

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 paramilitaries who started a war in the eastern Donbas region against Ukraine's military. In 2018, Ukraine declared the region to be occupied by Russia. 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.

In early 2014, the Euromaidan protests led to the Revolution of Dignity and the ousting of Ukraine's pro-Russian president Viktor Yanukovych. Shortly after, pro-Russian protests began in parts of southeastern Ukraine, while unmarked Russian troops occupied Crimea. Russia soon annexed Crimea after a highly disputed referendum. In April 2014, Russian-backed militants seized towns and cities in Ukraine's eastern Donbas region and proclaimed the Donetsk People's Republic (DPR) and the Luhansk People's Republic (LPR) as independent states, starting the Donbas war. Russia covertly supported the separatists with its own troops, tanks and artillery, preventing Ukraine from fully retaking the territory. The International Criminal Court (ICC) judged that the war was both a national and international armed conflict involving Russia, and the European Court of Human Rights judged that Russia controlled the DPR and LPR from 2014 onward. In February 2015, Russia and Ukraine signed the Minsk II agreements, but they were never fully implemented in the following years. The Donbas war became a static conflict likened to trench warfare; ceasefires were repeatedly broken but the frontlines did not move.

Casualties in the Russo-Ukrainian War include 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 between 400,000 and 1.5 mln. estimated casualties (killed and wounded) during the Russian invasion of Ukraine from February 24, 2022 till November, 2025.

The War in Donbas's deadliest phase (pre-2022) occurred before the Minsk agreements, aimed at ceasefire and settlement. Despite varied reports on Ukrainian military casualties due to underreporting, official figures eventually tallied, indicating significant military and civilian casualties on both sides. The war also saw a substantial number of missing and captured individuals, with efforts to exchange prisoners between conflicting parties. Foreign fighters and civilian casualties added to the war's complexity, with international involvement and impacts extending beyond the immediate conflict zones.

The Normandy Format (French: Format Normandie), also known as the Normandy contact group or Normandy Four, was a grouping of states who met between 2014 and 2022 in an effort to resolve the war in Donbas and the wider Russo-Ukrainian war. The four countries who made up the group—Germany, Russia, Ukraine, and France—first met informally in 2014 during the 70th anniversary of D-Day celebrations in Normandy, France. The group had a substantial role in mediating the Minsk agreements between 2014 and 2015 while further meetings in 2022 failed to deescalate rising tensions prior to Russia's invasion of Ukraine.
