Putnam, originally known as Aspinock, then part of Killingly, is a New England Mill town incorporated in 1855, and was made up from sections of Killingly, Pomfret and Thompson. The town was named in honor of Revolutionary War General Israel Putnam. The town was a key contributor in providing clothing and other goods to the Civil War soldiers. There were numerous mills and a train ran through the town, providing transportation for the goods being produced. Putnam was also the unlikely base of operations for the All-Russian Fascist Organization, a pre-war Russian emigre group that advocated fascism for the country under Anastasy Vonsyatsky.
