Waffen-SS troops massacre 560 people in Sant'Anna di Stazzema.

The Sant'Anna di Stazzema massacre was a German war crime committed in the hill village of Sant'Anna di Stazzema in Tuscany, Italy, in the course of an operation against the Italian resistance movement during the Italian Campaign of World War II. On 12 August 1944 the Waffen-SS, with the help of the Brigate Nere, murdered about 560 local villagers and refugees, including more than a hundred children, and burned their bodies. These crimes have been defined as voluntary and organized acts of terrorism by the Military Tribunal of La Spezia and the highest Italian court of appeal.

The Waffen-SS (German: [ˈvafn̩ʔɛsˌʔɛs], "Armed SS") was the combat branch of the Nazi Party's SS organisation. Its formations included men from Nazi Germany, along with volunteers and conscripts from both occupied and unoccupied lands.The Waffen-SS grew from three regiments to over 38 divisions during World War II, and served alongside the German Army, Ordnungspolizei (uniformed police) and other security units. Originally, it was under the control of the SS Führungshauptamt (SS operational command office) beneath Reichsführer-SS Heinrich Himmler, the head of the SS. With the start of World War II, tactical control was exercised by the High Command of the Armed Forces (Oberkommando der Wehrmacht, OKW), with some units being subordinated to Kommandostab Reichsführer-SS (Command Staff Reichsführer-SS) directly under Himmler's control.Initially, in keeping with the racial policy of Nazi Germany, membership was open only to people of Germanic origin (so-called Aryan ancestry). The rules were partially relaxed in 1940, and after Operation Barbarossa in June 1941, Nazi propaganda claimed that the war was a "European crusade against Bolshevism" and subsequently units consisting largely or solely of foreign volunteers and conscripts were also raised. These Waffen-SS units were made up of men mainly from among the nationals of Nazi-occupied Europe. Despite relaxation of the rules, the Waffen-SS was still based on the racist ideology of Nazism, and ethnic Poles (who were viewed as subhumans) were specifically barred from the formations.Members of the Waffen-SS were involved in numerous atrocities. At the post-war Nuremberg Trials, the Waffen-SS was judged to be a criminal organisation due to its connection to the Nazi Party and direct involvement in numerous war crimes and crimes against humanity. Former Waffen-SS members, with the exception of conscripts, who comprised about one third of the membership, were denied many of the rights afforded to military veterans.
