Edvard Beneš
In 1918 the party changed its name from Czech National Social Party to the Czech Socialist Party, in 1919 to the Czechoslovak Socialist Party and then in 1926 to the Czechoslovak National Socialist Party. Edvard Beneš took actual party leadership, although nominally it was his ally Václav Klofáč. Jiří Stříbrný and his supporters were expelled for disagreement with Václav Klofáč and Edvard Beneš. The expelled Stříbrný faction later cooperated with the fascist movement and National Democratic Party.
