A group of Christian miners' unions met at a conference in Salzburg, in 1921.
They agreed to hold conference in Innsbruck in 1922, at which the federation was established, as the International Christian Miners' Federation.
It established offices in Brussels, and affiliated to the International Federation of Christian Trade Unions.
