Czechoslovak National Council

The Czechoslovak National Council (or Czecho-Slovak National Council) was an organization founded by Czech and Slovak émigrés during World War I to liberate their homeland from Austria-Hungary. During the closing weeks of the war, the Czechoslovak National Council was formally upgraded to a provisional government and its members were designated to hold top offices in the First Czechoslovak Republic.
