For The Communist Labor Party of America (CLP), "Founding Convention" -- Chicago, IL -- Aug. 31 - Sept. 5, 1919;



And for The (old) Communist Party of America (CPA), "Founding Convention" -- Chicago, IL -- Sept. 1 - 7, 1919;



But, alas, Chicago was abandoned by the Comintern for the eastern shore of Lake Michigan to create The United Communist Party of America (UCP), "Joint Unity Convention" -- Bridgman, MI -- May 26 - 31, 1920;



But wait, the story goes on and on, including even Woodstock ("Joint Unity Convention" -- near Woodstock, NY -- May 15 - 28, 1921), where a very young Pat Boone was warmup for Pete Seeger.

And so it went - ref. The Communist Party of America (1919-1946) - Downloadable Documents.
