The Day of Volunteer Fighters is observed in Ukraine every March 14, celebrating the contributions of volunteer fighters to the country's military efforts. This holiday was officially established by the Verkhovna Rada in January 2017 and commemorates the formation of volunteer battalions in response to Russian military aggression beginning in 2014. The origins of these battalions trace back to the Euromaidan protests, which escalated into a revolution aimed at protecting protesters from police brutality. Following the annexation of Crimea, volunteer units were created to defend Ukraine's sovereignty, including the First Volunteer Battalion of the National Guard. The holiday highlights the role of these fighters in supporting the Armed Forces and the National Guard, particularly during the ongoing conflict since 2022. Various types of volunteer units, such as territorial defense battalions and independent volunteer groups, are recognized on this day.
