Utopian and Scientific Socialism by Friedrich Engels. Union Socialist Bookstore and Printing House, Granite, Illinois. 1918.

The center of Bulgarian immigration, and radicalism, in the United States was across the river from St. Louis in the southwest Illinois industrial towns of Granite City, Madison, and Venice; largely from the Bulgarian speaking area of Macedonia. Mainly affiliated with the Socialist Labor Party, Granite City saw a Bulgarian bookstore and printers run by the The Bulgarian Socialist Workers’ Union in America/Българският социалистически работнически съюз в Америка (BSRSA), an affiliate of the SLP. Of the four SLP language federations in the late 1910s and early 1920s, the Bulgarian Federation was the second largest with 478 paid members in 1923, almost 20% of the organization. Secretary-Treasurer of the Federation was Theodore Baeff. The SLP’s Bulgarian Federation published a weekly newspaper called Rabotnicheska Prosveta (Workers’ Enlightenment), which had an average subscription of 1,500 in 1922. With the formation of the Workers (Communist) Party of America, many Bulgarian SLP members joined the new organization. The CP developed its own Bulgarian Federation and published Suznanie (Consciousness), a weekly paper, from 1923 to 1937 out of Chicago, and later Detroit.
