The war in Ukraine has been the fastest growing and largest displacement crisis in Europe since World War II and has precipitated a regional refugee response of commensurate scale. Following the Russian Federation’s large-scale invasion of Ukraine in February 2022, the flow of refugees into neighbouring countries, and beyond, has been met by a remarkable mobilization of assistance – by national and municipal authorities, civil society actors, local volunteers, and refugees themselves, all contributing to ensure protection and meet the essential needs of those fleeing violence. The refugee response continues to address significant needs in host countries. Notably, the 2025-26 iteration of the plan reflects the increased national and local ownership of the response and greater investment by host governments and national civil society in the socio-economic inclusion of refugees.
