Today is Estonia’s Victory Day, which has been celebrated on June 23 every year since 1934. The date recalls the victory in the 1919 Battle of Vonnu of the Estonian military forces (and Latvian North brigade) and their allies over German forces (Baltische Landeswehr) who sought to re-assert Baltic-German control over the region. The battle was part of the 1918-1920 Estonian War of Independence, where the main adversary of the newly independent Estonia was Communist Russia.
Today, Victory Day also marks the contributions of all Estonians in their fight to regain and retain their independence. Estonian celebration of June 23 is ceremonially tied to the following Midsummer Day celebrations on June 24.
According to Estonian laws, the state flags are not to be lowered during the night between days.
