On 24 February 2022, Russia launched a large-scale invasion of Ukraine, one of its neighbours to the southwest. It marked a major escalation between the countries, which had been in a state of conflict since 2014. Following Ukraine’s Revolution of Dignity in 2014, Russia had annexed Crimea and Russian-backed separatist forces had seized part of the Donbas in eastern Ukraine, leading to an eight-year war in the region.
Due to the continued military build-up along the Ukrainian border, many neighbouring governments and aid organisations have been preparing for a potential mass displacement event for weeks prior to the actual invasion. The Ukrainian Defence Minister estimated in December 2021 that an invasion could potentially force between three and five million people to flee their homes.
