Republic (Latin: res publica - public matter) is a state where sovereignty belongs the nation, where all bodies of supreme power are authorised directly or indirectly by its citizens and are accountable to them. This is the form of state administration associated with a democratic political regime.
Laws in a republic are adopted by an elected body - a parliament (a representative legislative body), or directly by its citizens' vote.
The 1992 Constitution of the Republic of Lithuania, Article 1 reads, "The State of Lithuania shall be an independent and democratic republic. The wording of Article 1 of the Constitution of 1 August 1922 is as follows, "The State of Lithuania shall be an independent and democratic Republic. The sovereign powers shall belong to the Nation."
Ways were sought in the early 20th century to establish an independent State of Lithuania. The 18 February 1918 Act of Independence of Lithuania provides that the legislative power of the state shall belong to the Constituent Seimas. The State of Lithuania was a republic in 1920-1940.
The Republic of Lithuania was re-established when the Act on the Re-establishment of the State of Lithuania was adopted on 11 March 1990.
