Constitution Day in Lithuania Date in the current year: October 25, 2024

In 1990, Lithuania declared its independence from the Soviet Union. The old constitution of the Lithuanian Soviet Socialist Republic was replaced with a provisional constitution, which established a framework for the government of the Republic of Lithuania. It was based on the pre-Soviet constitution of the 1938, but maintained main elements of the Soviet-style government.

It took over two years to develop a new constitution not based on the Soviet model. Finally, contending parties agreed to a compromise between a parliamentary system and a presidential system. On October 25, 1992, a constitutional referendum was held in Lithuania. 75% of voters favored the new constitution, so the supreme law was adopted by a solid majority.

The Constitution of the Republic of Lithuania is the supreme law of Lithuania. It defines the characteristics of the state and fundamental rights and freedoms of its citizens, establishes the authority of the Seimas (parliament), the President, the Government and the judiciary etc.
