Balkans
With the start of the Second World War, all Balkan countries, with the exception of Greece, were allies of Nazi Germany, having bilateral military agreements or being part of the Axis Pact. Fascist Italy expanded the war in the Balkans by using its protectorate Albania to invade Greece. After repelling the attack, the Greeks counterattacked, invading Italy-held Albania and causing Nazi Germany's intervention in the Balkans to help its ally. Days before the German invasion, a successful coup d'état in Belgrade by neutral military personnel seized power.
