Soviet authorities, but survived and returned to Lithuania; Pranas Dovydaitis and Vladas Mironas were also sent to Siberia but died there. Kazys Bizauskas disappeared during the summer of 1941 while being transported to a Soviet prison in Minsk; he is presumed to have been shot along with a number of other prisoners. Donatas Malinauskas was deported to Russia on June 14, 1941 during the massive June deportation. Several of the surviving signatories emigrated. Jurgis Šaulys and Kazimieras Steponas Šaulys died in Switzerland. Antanas Smetona, Mykolas Biržiška, and Steponas Kairys emigrated to the United States and are buried there. Legacy The Act of February 16, proclaimed the re-establishment (atstatyti) of the Lithuanian state, making it the successor to the Lithuanian historical state, the Grand Duchy of Lithuania. In this respect the Council deviated from the resolution adopted by the Vilnius Conference which called for establishment (sudaryti) of a Lithuanian state. However, it was made clear that the new state would be quite different from the old Duchy: it was to be organized only in ethnic Lithuanian lands (except for the Vilnius region which was majority Polish) and was to be governed by democratic principles, as opposed to the multi-ethnic Duchy that had been ruled by an aristocracy. The termination of the ties binding Lithuania to other states was addressed to Germany, Russia, and Poland, all of which had their own plans for the country. Even though not addressed directly, the Act renounced any attempt to resurrect the former Polish–Lithuanian union. The Act of February 16, 1918, is the legal basis for the existence of present-day Lithuania, both during the interwar period and since 1990. The Act became one of the key elements during the restoration of Lithuania's independence from the Soviet Union in 1990. A paragraph in the Act of the Re-Establishment of the State of Lithuania, delivered on March 11, 1990, stated: This formulation emphasized the continuity of the two legal Acts. The Act of February 16, 1918, and its successor, the Act of March 11, 1990, are regarded as two of the most important developments of Lithuanian society in the 20th century. February 16 in Lithuania is an official holiday. On this day various ceremonies are hosted all across Lithuania. The 2014 commemoration included laying flowers at the signatories’ graves in Rasos Cemetery, awarding the Lithuanian National Prize, the hoisting of the three Baltic States’s flags at Daukantas Square,
