One of the three Baltic states, it is situated along the southeastern shore of the Baltic Sea, to the east of Sweden and Denmark. It is bordered by Latvia to the north, Belarus to the east and south, Poland to the south, and Kaliningrad Oblast (a Russian exclave) to the southwest.

It is described as the first major campaign fought entirely by air forces. The British officially recognise its duration as from 10 July until 31 October 1940 that overlaps with the period of large-scale night attacks known as the Blitz, while German historians do not accept this subdivision and regard it as a campaign lasting from July 1940 to June 1941., Lithuanians (singular "lietuvis/lietuv") are a Baltic ethnic group, native to Lithuania, where they number around 2,561,300 people. Another million or more make up the Lithuanian diaspora, largely found in countries such as the United States, Argentina, Brazil, Canada, Colombia, Russia, United Kingdom and Ireland. Their native language is Lithuanian, one of only two surviving members of the Baltic language family. According to the census conducted in 2001, 83.45% of the population of Lithuania identified themselves as Lithuanians, 6.74% as Poles, 6.31% as Russians, 1.23% as Belarusians, and 2.27% as members of other ethnic groups.
