Miners' Union in the Czechoslovak Republic (Czech: Svaz horníků v Československé republice) was a miners trade union in the Czech Lands (then part of Austria-Hungary) and later Czechoslovakia, affiliated to Odborové sdružení českoslovanské (OSČ).
[4][5] In 1918, the name was changed to Svaz horníků v Československé republice ('Miners' Union in the Czechoslovak Republic').
[6] The 1921–1922 split in the OSČ, when many communist trade unionists either were expelled or withdrew from the centre to form the parallel Mezinárodní všeodborový svaz (MVS), affected the Miners' Union somewhat differently from other unions.
A smaller group of coalminers from Northern Bohemia joined the MVS-affiliated Chemical Workers' Union.
[2] At the time, the general secretary of the Miners' Union was the Social Democratic MP Karel Brožík [cs].
