The Russian invasion of Ukraine began on February 24, 2022, when Russia launched a large-scale military attack on Ukraine. This invasion followed years of tension between the two countries, particularly after Russia annexed Crimea in 2014. The conflict has led to significant military and civilian casualties and has displaced millions of people. In response to the invasion, many countries, including those in the European Union and NATO, imposed economic sanctions on Russia and provided military and humanitarian support to Ukraine. The situation has raised global concerns about security, energy supplies, and the principles of national sovereignty.
