ENA declaration was made in 1918 about the restoration of the Lithuanian state, while the nation's leaders elected in the first direct and general elections held in 1920 established statehood and proclaimed the political structure of the modern Lithuanian republic. This account of the beginnings of 20th-century parliamentarism in Lithuania is aimed at a broader readership. The publication discloses the inner details related to the first democratic elections in Lithuania and searches for an answer as to why the organisation of general elections was postponed for more than two years after the declaration of the state's independence. It also reveals the undulating path in preparing for the first democratic general elections, and discusses the election results. The course of the special first session held on May 15, 1920 is also presented in detail, as well as the subsequent two years of the Constituent Assembly's work. The most important resolutions regarding the state and society that were passed by the parliament that affected domestic and foreign policy are named, also looking at the questions the parliament was unable to solve. The topics of the Constitution, land reform, national currency, social affairs, education and culture, and successes and failures of foreign policy in this parliament's term in office are also discussed.Separate attention is given to reconstructing a 'portrait' of the Constituent Assembly member: what kind of people were elected to parliament, and did they reflect the social picture of the Lithuanian public? There are sections on women in politics, and the representatives of national groups - Jews, Poles and Germans, in parliament. The publication mentions the influence of Lithuanian emigrants and World War I war refugees on the elections. Brief comparisons are made of the Lithuanian parliament and the 'constituent assemblies' in neighbouring countries. Finally, it is stated that the parliament brought to an end the 'temporary' period of the modern Lithuanian state of 1918. The state's internal and international situation in 1920-1922 more or less stabilised. The process of society's 'civilianhood' began, during which citizens, regardless of their social class, gender, nationality, confession or level of education had the chance to determine the political status of the Lithuanian state.
