Russia's unprovoked and unjustified military aggression against Ukraine, which started on 24 February 2022, triggered a firm and overarching political response by the European Union. Actions in the justice and home affairs policy field form integral parts of a successful and efficient response. The nine EU Agencies cooperating within the Justice and Home Affairs Agencies' Network (JHAAN) play a vital role in this process by contributing to the implementation of political decisions made at the European level, assisting Member States and other countries, and providing support to people affected by the war, in particular persons displaced from Ukraine.

The first overview of the response of JHA Agencies was prepared in 2022. The current overview was prepared by the EUAA Presidency of the JHAAN (2023) and covers the period February 2022-February 2023.
