The Voluntary Militia for National Security, commonly called the Blackshirts or squadristi, was originally the paramilitary wing of the National Fascist Party, known as the Squadrismo, and after 1923 an all-volunteer militia of the Kingdom of Italy under Fascist rule, similar to the SA in Nazi Germany. Its members were distinguished by their black uniforms and their loyalty to Benito Mussolini, the Duce (leader) of Fascism, to whom they swore an oath. The founders of the paramilitary groups were nationalist intellectuals, former army officers and young landowners opposing peasants' and country labourers' unions. Their methods became harsher as Mussolini's power grew, and they used violence and intimidation against Mussolini's opponents. In 1943, following the fall of the Fascist regime, the MVSN was integrated into the Royal Italian Army and disbanded.
