Castellammare War and “La Cosa Nostra”
Pages 33

Large scale bootlegging and the smuggling of alcohol had profound effects on the New York Mafi a, by contributing to an expansion in the number of Mafi osi and Families, and in propelling new Mafi a leaders to the forefront.1 Out of the ferment, according to its adherents, came La Cosa Nostra (LCN), the major effect of a legendary confl ict known as the “Castellammare War” of 1930 and 1931. But Mafi a power and structure was as diffuse and occasionally factious after the War as before it, with no dominant leadership type, power source, or developmental pattern subsequently emerging. The War was also far from the bloodbath usually portrayed.
