The Pioneers of Liberty (Pionire der Frayhayt) was the first Jewish anarchist organization in the United States.
[1] What started as the work of militants soon attracted members who would become noteworthy speakers and writers: David Edelstadt, Moshe Katz, Roman Lewis, Hillel Solotaroff, and Saul Yanovsky.
[2] The Pioneers first organized around the Haymarket defendants, circulating propaganda among Jewish workers on the Lower East Side.
The group ran Varhayt, a short-lived Yiddish anarchist newspaper in the United States between February and June 1889.
The Pioneers of Liberty also published an annual paper, Tfileh Zakeh "Pure Prayer", which circulated during the High Holy Days between 1889 and 1893.
