Lithuania Prime Minister. He was a Catholic Priest that was very active in the political history of Lithuanian independence. He was a member of the first modern national congress in the Lithuania, the Great Seimas of Vilnius; a signer of the Lithuanian Independence Act; and a member of the Vilnius Conference, which dealt with the process of establishing a Lithuanian state based on ethnic identity and language. He attended local Russian primary schools, a high school in what is now Jelgava, Latvia and finished the Vilnius Seminary in 1901. He received his masters degree in theology in Russia at St. Petersburg's Spiritual Academy, returning to Vilnius in 1904. As soon as the ban against using the Lithuanian language was lifted, his sermons and choir hymns were done in Lithuanian. He became an army chaplain and was promoted to the rank of Lithuanian army chief Brigadier General Chaplain, founder of the school of Vilnius National Defense, and active with the Christian youth groups. After the coup d'état in 1926, he was elected to the 3rd Seimas, and after a couple of years again returned to the priesthood. In 1938 he was offered the position of Prime Minister of Lithuania representing the Lithuanian Nationalists Union. In 1941 he was arrested and imprisoned but was freed a few days later by the Lithuanian Activist Front. At this point he had a chance to flee to the west but refused and stayed in Lithuanian. He was arrested by the Soviet police again in 1945. This time he collaborated with Soviet Police or NKVD and was forced to worked in Vilnius as their informant against other Lithuanian priests. Prior to this ordeal, he had been living off and on in the city of Kaunas. The results of this collaboration did not prove to be satisfactory with NKVD. Mironas was arrested for the third time on January 4, 1947, interrogated and subsequently was sent to Vladimir Prison in Russia to work at hard labor for seven years, but he died there of a stroke in 1953 as a political prisoner. The actual resting place of his body is unknown though it is know that he was buried at the prison site; this is a cenotaph. To honor this national patriot, there is a street in Kaunas named for him and the nation issued a postage stamp with his image.
