Union of Polish Syndicalists

It was based on the left wing of the syndicalist association Freedom and People, founded in Warsaw on October 21, 1939.

Association Freedom and People (Wolność i Lud, WiL) had two wings - military and civilian.

They consisted of small 3-5-persons groups, which cooperated with the Związek Walki Zbrojnej (Association of Armed Struggle, ZWZ).

In April 1941 Freedom and People was renamed to The Union of Polish Syndicalists, and in the summer of next year a group of officers decided to leave the Union and enter the general anti-Nazi organization, the Home Army (Armia Krajowa, AK).

In October 1942 first Assault Unit Zew was organized, and it was subject to headquarters of the Home Army.
