Lithuania is the largest and southernmost of the three Baltic states and occupies the southeastern shore of the Baltic Sea. Its capital is Vilnius, while Kaunas is another major urban and economic centre. Lithuania borders Latvia, Belarus, Poland and Russia's Kaliningrad region and has a Baltic Sea coastline. The country became independent from the Soviet Union in 1990 and subsequently joined NATO and the European Union in 2004.
It adopted the euro in 2015 and joined the Schengen Area in 2007. The EU records Lithuania's 2025 population at approximately 2.89 million and its area at 65,284 square kilometres. Lithuania has a parliamentary republic with a president as head of state and a single chamber parliament. Its geography, historical relationships with Poland and Belarus, Baltic identity and strategic position on NATO's eastern flank are important features of its contemporary character.
Lithuania has a relatively low lying landscape shaped by glacial processes, with plains, rolling hills, lakes, forests and wetlands. The country's highest point is only a little over 290 metres above sea level, illustrating its generally modest relief. The Baltic Sea coastline includes the Curonian Spit, a distinctive sand dune landscape shared with Russia and protected for its ecological and cultural significance. Lithuania's rivers include the Nemunas, which is the country's principal river system.
Forests and wetlands provide important habitats, while agricultural land occupies extensive areas of the interior. The climate is transitional between maritime and continental influences, producing relatively cool conditions compared with southern Europe. The country's landscape has therefore supported agriculture, forestry, settlement and recreation while also creating important environmental resources.
Lithuania has a long historical association with the Grand Duchy of Lithuania, which at its height formed a large political entity across much of eastern Europe. The Polish Lithuanian Commonwealth subsequently connected Lithuanian history closely with Poland. The territory was later incorporated into the Russian Empire before becoming an independent republic in 1918. Lithuania was occupied and annexed by the Soviet Union in 1940, followed by Nazi German occupation during the Second World War and renewed Soviet rule from 1944.
Lithuania restored its independence in March 1990, becoming one of the first Soviet republics to declare restoration of independence. Post independence development focused heavily on European and transatlantic integration. Membership of the EU and NATO in 2004 transformed Lithuania's economic, political and security relationships and strengthened its integration with western European institutions.
Lithuania's population is concentrated around Vilnius, Kaunas, Klaipeda and other urban centres, while rural areas contain relatively low densities. The country experienced substantial population decline after independence due to emigration, low fertility and ageing, although migration patterns have changed over time. Vilnius is the political, administrative, educational and increasingly important technology and services centre. Klaipeda has a major maritime function because it contains Lithuania's principal seaport. The population is predominantly Lithuanian, while Polish, Russian, Belarusian and other communities contribute to the country's demographic diversity. The Lithuanian language is a Baltic language and is closely related to Latvian, while being distinct from the Slavic languages spoken in several neighbouring areas.
Lithuania has a diversified economy centred on services, manufacturing, transport, logistics, technology, finance, food processing and other industries. Its geographical location gives it an important role in Baltic transport and trade networks. Klaipeda provides maritime access, while road and rail networks connect Lithuania with Latvia, Poland and other European markets. Lithuania has also invested in reducing energy dependence on Russia and strengthening connections with European energy systems. The country's economic transformation since independence has involved integration into EU markets, foreign investment and structural change from the Soviet industrial economy. EU data put Lithuania's 2023 GDP per capita at 33,000 euros, below the EU average of 38,100 euros.
Lithuania's political system is a parliamentary republic with a president serving as head of state and a prime minister leading the government. The Seimas is a unicameral parliament. Lithuania's foreign and security policy is strongly influenced by its membership of NATO and the EU and by its geographical proximity to Russia and Belarus. The country's historical experience of Soviet occupation contributes to the importance placed on sovereignty and security.
Lithuania has supported Ukraine since Russia's full scale invasion and has been active in European and transatlantic security discussions. Its relationship with Belarus is particularly significant because the two countries share a border, while the presence of Russia's Kaliningrad region immediately to the southwest creates another strategic consideration.
Lithuania's transport and energy geography has changed substantially since independence. Historically, infrastructure was oriented partly towards Soviet networks centred on Moscow, whereas integration into the EU has encouraged stronger east west and north south connections with Poland, Latvia and the wider EU. Rail infrastructure is being adapted to European standards through projects such as Rail Baltica, intended to improve connections between the Baltic states and continental Europe.
Energy diversification has also been strategically important, including the Klaipeda liquefied natural gas terminal and electricity interconnections with neighbouring EU states. These projects illustrate how infrastructure can alter geopolitical and economic geography. Lithuania's location between mainland EU territory and the Baltic Sea also makes it an important transit and logistics country.
Lithuania is a Baltic state whose contemporary geography reflects a combination of lowland physical landscapes, historical state formation, post Soviet transformation, EU integration and strategic proximity to Russia and Belarus. Vilnius dominates political and service functions, Kaunas provides a major secondary urban centre and Klaipeda provides maritime connectivity. Rural regions remain important for agriculture, forestry and environmental resources, although demographic decline has affected some areas.
EU and NATO membership has transformed Lithuania's international position, while infrastructure investment has strengthened connections with western Europe. Population ageing and migration remain important demographic considerations. The country therefore illustrates how a formerly Soviet economy can become deeply integrated into European political, economic, transport and security systems while retaining distinctive Baltic cultural and historical characteristics.
