Nabat -

"The Nabat Confederation of Anarchist Organizations, better known simply as Nabat (Набат), was an anarchist organization that came to prominence in Ukraine during the years 1918 to 1920. The area where it held the most influence is sometimes referred to as Makhnovia, though Nabat had branches in all of the major cities in southern Ukraine. "Nabat" is a Russian/Ukrainian word meaning tocsin, or an alarm bell toll. The group published a newspaper by the same name. - Wikipedia"
