The signatories of the Act of Independence of Lithuania were the twenty Lithuanian men who signed the Act of Independence of Lithuania on February 16, 1918. The signatories were elected to the Council of Lithuania by the Vilnius Conference in September 1917 and entrusted with the mission of establishing an independent Lithuanian state. The proclaimed independence was established only in late 1918, after Germany lost World War I and its troops retreated from Lithuanian territory. What followed was a long process of building the state, determining its borders, and gaining international diplomatic recognition. The signatories succeeded in their mission and independent Lithuania survived until the Soviet Union occupied the state on June 15, 1940.
Their political, professional, and social backgrounds were diverse. Several rose to political prominence; Antanas Smetona and Aleksandras Stulginskis were later elected Presidents of Lithuania and Jonas Vileišis went on to become mayor of Kaunas, the temporary capital of Lithuania. After Lithuania lost its independence during World War II, six of the surviving signatories were sent to prison or executed by the Soviet government and six others emigrated to Western countries.
The signatories came from a variety of social backgrounds. Four had been born to Lithuanian noble families: Donatas Malinauskas, Stanisław Narutowicz, Jonas Smilgevičius, and Mykolas Biržiška. The other 16 were the children of farmers. The eldest of the signatories was Jonas Basanavičius, who was 67 at the time, and the youngest Kazimieras Bizauskas, who was 25. Of the remainder, three were in their fifties, six were in their forties, eight were in their thirties, and one was in his twenties. All, with the exception of Saliamonas Banaitis, had completed tertiary education. In 1926 he enrolled at Kaunas University, but his studies were left unfinished due to his death in 1933. In terms of educational background, the Council was dominated by eight lawyers. The group also included four priests, two agronomists, two financiers, one physician, one economist, and an engineer. The majority of the signatories had received their higher education outside of Lithuania, since at the time Lithuania had no universities - Vilnius University was closed after the January Uprising in 1863. Five graduated from Saint Petersburg University, four from Moscow University, and two from Saint Petersburg State Institute of Technology.
