Young Communist League of Poland

The founding congress of ZMKwP was held on March 22, 1922.[1][4][3] Alfred Lampe was elected Secretary of the Central Committee of ZMKwP at the time of its first congress.[2][5] The other members of the Central Committee of ZMKwP were Bronisław Berman, Leon Holcer, Władysław Kniewski, Tadeusz Oppman, Stanisław Teszner, Antoni Werner and Włodzimierz Zawadzki.[5]

In 1923 the left opposition of the Polish League of Socialist Youth (ZPMS) joined ZMKwP.[6] Komtsukunft, the youth wing of the Jewish Communist Labour Bund in Poland, merged into ZMKwP in March–April 1923.[2][7] ZMKwP also absorbed dissidents from the Poale Zion Left and Fareynikte factions.[2]

In 1925 ZMKwP organized a pioneer movement for children, Pionier. Later followed the setting up of organization amongst secondary school students.[8]

ZMKwP had some 3,700 members as of June 1926. As of July 1931, membership had increased to around 7,000.[2] KZMP had a larger percentage of Jewish membership than the mother party.[9][10] As of 1930, 51% of KZMP members were Jews, 19% Poles, 18% Ukrainians and 12% Bielorussians.[9][11] The Jewish dominance in the membership hindered expansion between in rural areas, as Jewish-dominated branches in small towns were largely disconnected from the peasantry in the surrounding countrysides.[2] However, by 1933 the ethnic proportions had changed with 33% of KZMP members being Poles, 31% Jews, 19% Bielorussians and 17% Ukrainians.[9] The decline in the percentage of Jewish members corresponded to an increase of recruitment amongst the peasantry. By 1932 50% of KZMP members hailed from the peasantry.[2]

The publication Towarzysz ('Comrade') was the organ of the Central Committee of ZMKwP/KZMP, published from Warsaw. In 1937, it changed name to Towarzysz Młodzieży ('Young Comrade').[12][13]

In 1938 KZMP was dissolved, along with the mother party, by a decision of the Executive Committee of the Communist International.[1]
