The National-Christian Labour Union (Polish: Narodowo-Chrześcijańskie Zjednoczenie Pracy, NChZP) was a political organization[1] that united supporters of Sanation in the Silesian Voivodeship.
[2][3] It was created in November 1927 with the initiative of Voivode Michał Grażyński (initially under the name Polish Labour Union) as a bloc uniting not only Piłsudskiites, but also the Union of Silesian Catholics under priest Józef Londzin and the Silesian chapters of the National Workers' Party, PSL „Piast” and the Popular National Union.
Priest Londzin became the leader of the Union, with Emanuel Grim succeeding him following his death.
The NChZP united nationalist ideology with the plight of labourers and elements of Silesian regionalism.
[3] During the 1930 elections, the Union was endorsed by the Polish Socialist Party – former Revolutionary Faction, dissidents of the Polish Christian Democratic Party and ephemeral Silesian National Bloc, which considered itself the representatives of the local population.
