The Office of the United Nations High Commissioner for Human Rights (OHCHR) verified a total of 46,085 civilian casualties during Russia's invasion of Ukraine as of May 31, 2025. Of them, 32,744 people were reported to have been injured. However, OHCHR specified that the real numbers could be higher. How many people have died during the war in Ukraine? OHCHR has estimated the number of deaths of civilians, or non-armed individuals, in Ukraine at 13,341 since the start of the war on February 24, 2022. The highest death toll was recorded in March 2022, at over 3,900. The figures on soldier deaths are reported by Russia and Ukraine’s governmental authorities, but they cannot be verified at this point and thus need to be taken with caution. Conflict-related deaths in Ukraine from 2014 to 2021 After Russia annexed Crimea in 2014, Ukraine has seen a military conflict between the government and the Russia-supported separatist regions of Donetsk and Luhansk. OHCHR estimates that between 14,200 and 14,400 people, including civilians and military personnel, were killed in relation to that conflict from April 14, 2014, to December 31, 2021. Of them, at least 3,400 were civilians.

As of May 31, 2025, 13,341 civilian deaths in Ukraine were reported by the Office of the United Nations High Commissioner for Human Rights (OHCHR) due to the Russian invasion that started on February 24, 2022. OHCHR specified that the real figures could be significantly higher. Furthermore, the increases in the figures each week should not be attributed to that week only because they include adjustments from previous weeks.

Over the course of the Second World War, approximately 44.5 percent of the Soviet population and 8.7 of Soviet territory was occupied by the Axis forces at some point. Despite being allied in the war's early stages, with both countries invading Poland in 1939 via the Molotov-Ribbentrop Pact, Germany would launch Operation Barbarossa, the invasion of the USSR, in 1941, which would become the largest military invasion in history. Movement of the Eastern Front The surprise invasion began on June 22, and Axis forces caught the Soviets off-guard, quickly pushing their way eastward along a frontline that stretched from the Baltic to Black seas. The length of the front-line allowed Axis forces to execute pincer movements around cities and strongholds, which cut off large numbers of Soviet soldiers from their supply lines, as well as preventing reinforcements; in this process millions of Soviet troops were taken as prisoner. Within three weeks, the Germans had taken much of present-day Poland, Belarus, and the Baltic states, before taking Moldova and Ukraine in September, and pushing into western Russia between September and December. The front lines had reached the outskirts of Moscow by November, before exhaustion and cold weather helped Soviet forces hold the line and stall the German offensive. The Red Army was then able to regroup and turning the Germans' own tactics against them, using two-pronged attacks to encircle large numbers of troops, although harsh weather made this stage of the conflict much slower.

The lines remained fairly static until mid-1942, when the Germans focused their offensive on the south, concentrating on the Caucasian oil fields and the Volga River. By November 1942, Axis forces had pushed into these regions, establishing what would ultimately be the largest amount of occupied Soviet territory during the war. Once again, winter halted the Axis advance, and allowed the Red Army to regroup. Learning from the previous year, the Axis command strengthened their forces near Moscow in anticipation of the Soviet counter-offensive, but were caught off-guard by a second counter-offensive in the south, most famously at Stalingrad. The Battle of Stalingrad would come to epitomize the extreme loss, destruction, and brutality of war on the eastern front, with conflict continuing in the city months after the rest of the Axis forces had been pushed west. As 1943 progressed, the Red Army gained momentum by targeting inferiorly-trained and equipped non-German regiments. The spring then became something of a balancing act for the Axis powers, as the Soviets consistently attacked weak points, and German regiments were transferred to reinforce these areas. In the summer of 1943, the front line was static once more, however the momentum was with the Soviets, who were able to capitalize on victories such as Kursk and gradually force the Axis powers back. By 1944, the Red Army had re-captured much of Ukraine, and had re-taken the south by the summer. When the Western Allies arrived in France in June, the Soviets were already pushing through Ukraine and Belarus, towards Berlin. In August 1944, the last Axis forces were pushed out of Soviet territory, and Soviet forces continued their push towards the German capital, which fell in May 1945. Soviet death toll In addition to the near-five million Soviet troops who died during Operation Barbarossa, millions of civilians died through starvation, areal bombardment, forced labor, and systematic murder campaigns. Due to the nature and severity of Soviet losses, total figures are difficult to estimate; totals of 15-20 million civilians and 7-9 million military deaths are most common. Further estimates suggest that the disruption to fertility, in addition to the high death toll, meant that the USSR's population in 1946 was 40 million lower than it would have been had there been no war.
