Lithuania is a country located in northeastern Europe, on the eastern shore of the Baltic Sea. It has a rich and complex history, dating back to the 13th century.

• The Grand Duchy of Lithuania was established in the 13th century and it quickly became one of the largest and most powerful medieval states in Europe, comprising present-day Lithuania, parts of Poland, Belarus, and Ukraine. The Grand Duchy of Lithuania was formed by the union of Lithuanian and Ruthenian tribes under the rule of the Gediminids dynasty. The Grand Duchy was a multi-ethnic and multi-lingual state.
• In the 16th century, the Grand Duchy became a major European power and a leading center of the Renaissance. During this period, Lithuania expanded its territory, and it reached its peak in the late 16th century under the rule of the Vasa dynasty.
• In the late 18th century, the Polish-Lithuanian Commonwealth was dissolved, and Lithuania was annexed by the Russian Empire, this marked the end of the Lithuanian statehood for over a century. During this time, the Russian Empire implemented a policy of russification, which aimed to assimilate the Lithuanians, and Lithuanian language and culture were suppressed.
• After the First World War, Lithuania declared its independence, and it became a republic, but it was soon occupied by the Soviet Union. Lithuania remained under Soviet control until 1990, when it declared its independence once again and became a parliamentary democracy.
• Since then, Lithuania has made significant progress in developing its economy, and it has become a member of the European Union, the North Atlantic Treaty Organization (NATO) and the Eurozone. The country has a diverse culture, with influences from its neighboring countries and its history. Lithuanian is the official language, and the currency is Euro.
