Václav Jaroslav Klofáč (September 21, 1868 – July 10, 1942) was a Czech politician and one of the founders of the Czech National Social Party. He was born in 1868 in Německý Brod. Klofáč became one of the best known radical nationalist Czech politicians in the Habsburg Monarchy.
Václav Klofáč grew up in humble circumstances, the son of a courtroom messenger, he knew poverty and went through a number of experiences that allowed him to understand and sympathize with the working-class. Klofáč’s education began in Německý Brod Gymnasium and then at the University of Prague in the late 1880s. He was originally enrolled in the Universities Medical School but transferred into the school of arts and sciences where he studied philosophy. Václav participated in journalism and student politics. His political career began during his years as a student at Charles University in Prague. While attending the University Klofáč became co-founder of the Czech students progressive movement. He was also involved in the Young Czech Party, who defeated the Old Czechs in the Reichstrat election of 1891, and frequently wrote for the Časopis Pokrového Studentstva. After graduation, Julius Gregr editor of Národní Listy convinced Klofáč to write for the paper where he was quickly promoted to editor. But Klofáč became unhappy with what he viewed as the excessive compromising of the Young Czechs with the Habsburg government.
His frustrations with the Young Czechs led Klofáč to become one of the founders of the National Social party (originally the National Workers party) in 1898. He was elected to the Austrian parliament for the first time in 1901 along with his colleagues Václav Choc and Václav Fresl, where he used his seat in the parliament to attack the government for what he believed were its anti-Czech, militarist and Catholic policies. Unlike many nationalists of his day, Klofáč was an ardent supporter of women's right to the vote. The stridency of his anti-Habsburg politics led to his arrest by the Austrian authorities on charges of treason in 1915. Although he was sentenced to death, Klofáč was amnestied in 1917 along with many other prominent Czech politicians. In 1939 Klofáč escaped a second incarceration, when Bohemia was occupied by the Germans, due to his impending death. From January 1919 to May 1920 Klofáč served as Czechoslovakia’s minister of national defense.
