Russian-occupied territories of Ukraine
The Russian-occupied territories of Ukraine are areas of Ukraine that are currently controlled by Russia in the course of the Russo-Ukrainian War. In Ukrainian law, they are defined as the "temporarily occupied territories of Ukraine" (Ukrainian: Тимчасово окупована територія України, romanized: Tymchasovo okupovana terytoriia Ukrainy).
The occupation started in 2014 following Russia's invasion and annexation of the Crimean peninsula, and its de facto takeover of Ukraine's Donbas[1] during a war in eastern Ukraine.[2] In 2022, Russian forces initiated a full-scale invasion of the nation and successfully occupied more territory throughout the country. However, after continued fierce Ukrainian resistance, coupled with logistical challenges[3] (e.g. the stalled Russian Kyiv convoy), the Russian Armed Forces announced their withdrawal from Chernihiv, Kyiv, Sumy, and Zhytomyr oblasts in early April.[4]
In early September 2022, Ukrainian forces ended the months-long stalemate on the front lines with a successful counteroffensive in the Kharkiv region, inflicting a major defeat on Russian forces by forcing their retreat.[5] Then later in November, Ukrainian forces once again achieved a major success with a southern counteroffensive retaking the city of Kherson on 11 November.
On 30 September 2022, Russia announced the annexation of Donetsk, Kherson, Luhansk and Zaporizhzhia oblasts, despite only occupying part of the claimed territory. The UN General Assembly responded by passing a resolution rejecting this annexation as illegal and upholding Ukraine's right to territorial integrity.[6]
Before 2022, Russia occupied 42,000 km2 (16,000 sq mi) of Ukrainian territory (Crimea, and parts of Donetsk and Luhansk), and occupied an additional 119,000 km2 (46,000 sq mi) after its full-scale invasion by March 2022, a total of 161,000 km2 (62,000 sq mi) or almost 27% of Ukraine's territory.[7] By 11 November 2022, the Institute for the Study of War calculated that Ukrainian forces had liberated an area of 74,443 km2 (28,743 sq mi) from Russian occupation,[8] leaving Russia with control of about 18% of Ukraine's territory.[9] During the entire 2023, the Russian forces only captured 518 km2 (200 sq mi) of Ukrainian territory, despite huge losses on the battlefield.[10]
