Lithuanian nationalism is a political and cultural movement that seeks to promote the interests and identity of the Lithuanian people. It emerged in the 19th century as a response to foreign domination, particularly from Russia and Poland. The movement emphasized the importance of the Lithuanian language, culture, and history, fostering a sense of unity among Lithuanians. The culmination of Lithuanian nationalism occurred in 1918 when Lithuania declared independence after World War I. This movement played a crucial role in the country's efforts to maintain sovereignty and cultural identity, especially during periods of occupation in the 20th century. Today, Lithuanian nationalism continues to influence politics and society in Lithuania.
