Concentration camp
However, in 1943, after Mussolini had lost power, Nazi Germany took over northern and central Italy.  They also put Mussolini back in power.  The Nazis created concentration camps to hold Italian Jews and other prisoners until they could be sent to death camps.  In one of these concentration camps, called La Risiera di San Sabba, the Nazis tortured and murdered about 5,000 people.  Many of these people were "political prisoners" - people who disagreed with the government.
