"Although there is no organizational connection, the lineage of antifa in America can be traced to Weimar Germany,[28] where the first group described as "antifa" was Antifaschistische Aktion, formed in 1932 with the involvement of the Communist Party of Germany.[29]" WIKIPEDIA.  "Antifa traces its roots to the 1920s and ’30s, when militant leftists battled fascists in the streets of Germany, Italy, and Spain. When fascism withered after World War II, antifa did too. But in the ’70s and ’80s, neo-Nazi skinheads began to infiltrate Britain’s punk scene. After the Berlin Wall fell, neo-Nazism also gained prominence in Germany. In response, a cadre of young leftists, including many anarchists and punk fans, revived the tradition of street-level antifascism." THE ATLANTIC
