As brother Richard and I cleaned out Mom and Dad's house in Huntsville during 2023 and 2024, we found lots of interesting family memorabilia and a few really unexpected items. This flyer falls into the latter category.
We found it in material Dad brought from Gadsden after his mother Rosa Mae Wright died in 1993. My grandfather Amos J. Wright, Sr., worked for the L&N Railroad there for many years, most of them as a yard foreman. One of his duties included checking boxcars to make sure they were completely empty. Perhaps he found it in one of those. If so, why he kept it is a mystery. Perhaps it came into their family papers some other way.
The Socialist Union Party was one of several small groups spun out of the Socialist Labor Party in the 1930s. These organizations were known as De Leonist after Daniel De Leon, an early leader in the SLP, which was the first socialist political party in America and founded in 1876. In the mid-1930s Abraham Ziegler was expelled from the SLP and joined another De Leonist group that soon faded. Then he and a few others started the SUP in 1939; it lasted until 1941.
This anti-conscription flyer is dated August 1940. An address is given for the Socialist Union Party, 140 Fourth Avenue, Brooklyn. As far as I could determine from Google Maps, the building still exists, located between Luna's Tire Shop and a Papa John's Pizza. According to the Wikipedia article on "Conscription in the United States", support for compulsory military service for young men was building in the country in the summer of 1940 as the war in Europe heated up.
Given the Scottsboro Boys trials and labor organization/unrest history in the state, the American Communist Party was very active in Alabama in the 1930s and beyond. For detailed information see Robin D. Kelley's Hammer and Hoe: Alabama Communists during the Great Depression [2015] and Mary Stanton’s book Red, Black, White: The Alabama Communist Party, 1930–1950 [2020]. I would imagine other political groups beyond Republicans and Democrats were also present in the state to one degree or another. This flyer would seem to be evidence about one little known socialist group at least.
