Estonian War of IndependenceThe Estonian War of Independence, also known as the Estonian Liberation War, was a defensive campaign of the Estonian Army and its allies, most notably the United Kingdom, against the Bolshevik westward offensive of 1918–1919 and the 1919 aggression of the Baltische Landeswehr. The campaign was the struggle of the newly established democratic nation of Estonia for independence in the aftermath of World War I. It resulted in a victory for Estonia and was concluded in the 1920 Treaty of Tartu.
SuomenlinnaSuomenlinna (ˈsuo̯menˌlinːɑ; until 1918 Viapori, ˈviaˌpori), or Sveaborg (ˈsvɛːɑˈborj), is an inhabited sea fortress composed of eight islands, of which six have been fortified; it is about 4 km southeast of the city center of Helsinki, the capital of Finland. Suomenlinna is popular with tourists and locals, who enjoy it as a picturesque picnic site. Originally named Sveaborg (Castle of the Swedes), or Viapori as referred to by Finnish-speaking Finns, it was renamed in Finnish to Suomenlinna (Castle of Finland) in 1918 for patriotic and nationalistic reasons, though it is still known by its original name in Sweden and by Swedish-speaking Finns.
