Born on 22 October 1910 in Kareivonys, Kaišiadorys district. Died 25 01 2007.
After some education in his native village, he entered the S.Daukantas Teachers' Seminary in Kaunas and successfully graduated in 1928. He taught at Vepriiai, Žiežmariai and Vaiguva primary schools and at Marija Pečkauskaitė Gymnasium in Kaunas. He wanted to be an officer, so he went to the Military School, where he studied from 1931-1932. In 1940, he graduated from the Faculty of Humanities at VMU, and in 1942-1944 he was the headmaster of Kaunas 10th gymnasium. In 1944, Kralikauskas left Lithuania after burying his wife (who died in 1942 at the age of 25) and one of his twins. He left his other son, Virgilijus, in the care of his grandmother. From 1948, Kralikauskas lived in Canada, working in the Picle Crow gold mines; he returned to Lithuania in 1996.
Kralikauskas made his debut with a collection of short stories about school life, Septyni swordijai / Seven Swords (1937). While living in exile, he published Cave People (1954), a short story based on his personal experience of working in the mines, and Šviesa lange (1960). These works are dominated by the motifs of human loneliness, depicting a harsh environment that is exhausting to the individual spirit. Later, Kralikauskas turned to historical prose, representing significant stages in the nation's existence. He devoted a lot of attention to the Mindaugas era in his novels Titnagas Ugnis (The Fire of Titnago, 1962), The Assassination of Mindaugas (1964), Vaišvilkas (1971), Tautvila (1973) and Mindaugas (1995). The historical biographical novels Martynas Mažvydas in Vilnius (1976) and Įkaitę Vilniaus akmenys (1979) depict 16th-century Lithuanian cultured people, with a strong emphasis on the context of the action. The novel After the Ultimatum (1980) and the short story Vėlinės (1988), works based on factual material and authentic testimonies, tell the story of the events of 1941-1944 in Lithuania. Kralikauskas presented his concept of the historical novel and a kind of self-analysis of his work in his book Ąžuolai piliakalnyje: Dzhmelmenys ir problemy (The Oaks in the Castle Mound: The Depths and Problems of Nine Historical Novels) (1984). A beautiful, comprehensive monograph on this novelist was written in 2002 by Prof. Elena Nijolė Bukelienė.
