The party was founded in late October 1929[1] and was a member of the International Communist Opposition[2] until it was expelled from that organisation in 1934 and gradually moved towards pro-Nazi positions.
The split had been preceded by an unorthodox coalition in the Strasbourg municipal elections of May 1929 in which local communists had formed an alliance with clerical and autonomist forces.
[1] The Strasbourg communists had also revived the newspaper Die Neue Welt, which had been closed down in 1923, as an alternative to l'Humanité d'Alsace-Lorraine.
The new party had at the time of its foundation, the mayor of Strasbourg, Charles Hueber, and was supported by the majority of the municipal council.
The party conceptualized fascism as largely synonymous to centralism and compared the Italization of South Tyrol with Frenchification of Alsace.
