In the form of a biographical sketch the study introduces Antonín Kalina as a politician, diplomat and a long-standing deputy in the Czech Diet and Reichsrat, representing the Czech Constitutional Progressive Party. The text summarizes his pre-war as well as war activities, and since this period is generally less known, special attention is also paid to his activities after the World War I. As his career of a deputy was his most signifi cant political period, a review of activities of the Czech Constitutional Progressive Party and its representation in legislative bodies (Reichsrat, Czech Diet) in 1908–1918 is presented in the fi rst part of the study. Th is part explores the social and political setting and its infl uence on Antonín Kalina. Other significant personalities of the Czech Constitutional Progressive Party are mentioned briefly as well, particularly Kalina’s Parliamentary colleagues. Th e second part of the study focuses on Kalina’s activities after 1918, when he became the first Czechoslovak ambassador in Yugoslavia (more exactly, then the Kingdom of Serbs, Croats and Slovines). Th is part explores the beginning and work of the Czechoslovak diplomatic service in Yugoslavia during fi rst post-war years, which were not without diffi culties and shortcomings.
