Count Casimir Dunin Markievicz (Polish: Kazimierz Dunin-Markiewicz, 15 March 1874 – 2 December 1932) was a Polish portrait, category and landscape artist, playwright and theatre director, and a member of the Russian nobility.
Markievicz attended the State Gymnasium in Kherson, and studied law at the University of Kyiv. In 1895 he transferred to the Academy of Arts in Paris. He was married at the time, with a son named Stanislas, but his wife died in 1899. Whilst in Paris, he met Constance Gore-Booth (later known as the Countess Markievicz). They married in London in 1900 and their daughter, Maeve, was born the following year. From 1902 the couple lived in Dublin.
Markievicz was part of the literary circle that centred on W. B. Yeats and the Abbey Theatre. In 1910 he formed his own theatre company, the Independent Dramatic Company, which staged plays written by himself and starring his wife, Constance. In 1913 Markievicz moved to present-day Ukraine, and never returned to live in Ireland. However, he did correspond with his wife in Dublin and he was by her side when she died in 1927.
Towards the end of his life Markievicz was active in Warsaw, as well as a correspondent for English magazines, such as the Londoner Daily News. He also wrote the screenplay of a 1920 Polish film, Powrót, directed by Aleksander Hertz. The largest part of his art collection is held in Dublin, some remain in Poland (National Museum, Kraków and in private collections). His talent lent itself particularly to the large oil portraits of Polish presidents Piłsudski and Wojciechowski. A catalog for his works is still pending.
