Konstantine Gamsakhurdia (Georgian: კონსტანტინე გამსახურდია) (May 3, 1893 – July 17, 1975) was a Georgian writer and public figure, who, along with Mikheil Javakhishvili, is considered to be one of the most influential Georgian novelists of the 20th century. Educated and first published in Germany, he married Western European influences to purely Georgian thematic to produce his best works, such as The Right Hand of the Grand Master and David the Builder. Hostile to the Soviet rule, he was, nevertheless, one of the fewest leading Georgian writers to have survived Stalin era repressions, including his exile to a White Sea island and several arrests. His works are noted for their character portrayals of great psychological insight. Another major feature of Gamsakhurdia’s writings is a new subtlety he infused into Georgian phrasing, imitating an archaic language to create a sense of oldness.

Konstantine Gamsakhurdia's son, Zviad, became a notable Soviet era dissident who was subsequently elected the first President of Georgia in 1991, but ended his career and life in the civil war in 1993.

Born into a petite noble family in Abasha in western Georgian province of Mingrelia, then under the Imperial Russian rule, Gamsakhurdia received early education at the Kutaisi gymnasium and then studied in St. Petersburg, where he quarreled with Nicholas Marr. He spent most of the World War I years in Germany, France, and Switzerland, taking his doctorate at the Berlin University in 1918. As a Russian subject, he was briefly interned at Traunstein in Bavaria where Thomas Mann sent him chocolate. Gamsakhurdia published his first poems, and short stories early in the 1910s, influenced by German Expressionism and French Post - Symbolist literature. While in Germany, he regularly wrote for the German press on Georgia and the Caucasus, and was involved in organizing a Georgian Liberation Committee. After Georgia’s declaration of independence in 1918, he became an attaché in Georgia’s embassy in Berlin, responsible for repatriation of Georgian World War I prisoners and placing Georgian students in German universities.

Gamsakhurdia met the 1921 Bolshevik takeover of Georgia with hostility. He edited the Tbilisi based literary journals and for a short time led an “academic group” of writers which placed artistic values above political correctness. Gamsakhurdia published his writings in defiance to the growing ideological pressure and he went ahead to lead a peaceful protest rally on the anniversary of Georgia’s forcible Sovietization in 1922. In 1925, Gamsakhurdia published his first and one of the most impressive novels The Smile of Dionysus (დიონისოს ღიმილი), which took him eight years to write. It is a story of a young Georgian intellectual in Paris who is detached from his native society and remains a complete stranger in the city of his ideals. This novel, like his earlier works, was partially "Decadent", and did not please the Soviet ideologists, who suspected him of fostering discontent.

After the suppression of the 1924 anti-Soviet uprising in Georgia, Gamsakhurdia was excluded from the Tbilisi State University where he taught German literature. Soon he was arrested and deported to the Solovetsky Islands in the White Sea where he was to spend a few years. On his release, Gamsakhurdia was forced to keep silent. On the verge of suicide, the writer fought his depression by translating Dante. Early in the 1930s, he obtained Lavrentiy Beria's protection and was able to resume writing, with an attempt at "socialist" novel Stealing the Moon (მთვარის მოტაცება, 1935-6), a story of love and collectivization in Abkhazia. Next came the psychological novella Khogais Mindia (ხოგაის მინდია, 1937), yet another appeal in classical Georgian literature to this Khevsur myth. Beria was critical of these works, though. Soon Gamsakhurdia was arrested for an affair with Lida Gasviani, a young charming Trotskyite director of the State Publishing House, but interrogated and released by Beria who told him ironically that sexual relations with enemies of the people were permitted.

Gamsakhurdia survived the Joseph Stalin - Lavrentiy Beria purges, which destroyed a large part of Georgian literary society, but resolutely refused to denounce others. He had to pay a tribute to the Stalinist dogma, conceiving a novel on Stalin’s childhood in 1939. However, as the first published part of this work was not approved by the authorities, it was promptly discontinued and withdrawn from public libraries.

At the height of the Stalinist terror, Gamsakhurdia turned to the more favored genre of historical and patriotic prose, embarking on his magnum opus, the novel The Right Hand of the Grand Master (დიდოსტატის მარჯვენა, 1939), set in the 1110s/20s around the legend of the building of the Cathedral of Living Pillar against a broad panorama of 11th century Georgia. It deals with the tragic fate of the devoted architect Konstantine Arsakidze, from whom King Giorgi I commissions a cathedral, but Arsakidze becomes the king’s rival in love for the beautiful Shorena, a daughter of the rebellious nobleman. The clash of powerful human passions, between illicit love and duty, culminates in the mutilation and execution of Arsakidze at Giorgi’s behest. The story conveys a subtle allegorical message, and the harassed artists of Stalin’s era can be recognized in Arsakidze.

Gamsakhurdia’s major post World War II works are The Flowering of the Vine (ვაზის ყვავილობა, 1955), which deals with a Georgian village shortly before the war; and the monumental novel David the Builder (დავით აღმაშენებელი, 1942 – 62), which is a tetralogy about the venerated king David the Builder who ruled Georgia from 1189 to 1125. This work won for the author a prestigious Shota Rustaveli State Prize in 1962. Gamsakhurdia also wrote a biographical novel about Goethe, and literary criticism of Georgian and foreign authors. Publication of his memoirs, Flirting with Ghosts (ლანდებთან ლაციცი, 1963) and of his testament (1959) was aborted at that time. He died in 1975 and was interred at his mansion which he called a "Colchian Tower", refusing to be buried in the Mtatsminda Pantheon because he detested that Jesus and Judas were buried side by side there, referring to the proximity of the graves of the national writer Ilia Chavchavadze and his outspoken critic and political foe, the Bolshevik Filipp Makharadze.
