The Ashkenazum was an organized crime group active in Argentina in the first half of the 20th century. Ashkenazum was founded by Simon Rubinstein as a splinter group from the larger Zwi Migdal, an organized crime group that stretched across five continents and specialized in the sex trafficking of Eastern European Jewish girls.^[1]

Simon Rubinstein arrived in Buenos Aires in 1900 from Odessa, and there he quickly acquired control of a condom factory. He was a notorious silk smuggler and became affiliated with the Zwi Migdal. At the height of his operation, he had 700 agents in Argentina trafficking women for him.^[2]

Like the larger Zwi Migdal, the Ashkenazum also had its own cemetery outside of Buenos Aires.^[3]
