processing of goods mainly to olive oil, currants, and tobacco. Cereals led among heavy food imports, since Greece could not feed its own population on its domestic production.
When Italian forces attacked from occupied Albania on 28 October 1940, the Greeks adopted a strategy of holding lightly on their left, allowing Italian columns to advance deep into the barren Pindus, while they resisted strongly and then launched a counteroffensive on their right. Their advance brought the Greeks into Albania, where they presented a serious threat to the left flank of the Italian forces to the south.
Despite their victories over the Italian invaders, the Greeks could not long resist the fast-moving German forces that intervened in the Greek-Italian conflict on 6 April 1941. Greece surrendered to the Germans on 23 April, and was then required to surrender to the Italians as well. This submission to an enemy they had all but defeated aroused the resentment of the Greeks. Later coupled with the occupation of most of Greece by Italian forces, it contributed in no small measure to the rise of the Greek resistance movement.
III. Yugoslavia
A most heterogeneous state, the homeland of the Serbs, Croats, and Slovenes, derived its name from the Slavic terms for South Slav and became a state following World War I. Yugoslavia had a population of nearly sixteen millions by 1941, and in geographic area was slightly smaller than the state of Wyoming. Almost one half of its inhabitants, or six and one-half million people, were Serbs, occupying the areas of the former Kingdom of Serbia and the old provinces of Bosnia, Hercegovina, and Dalmatia. The Serbs used the Cyrillic alphabet, professed mainly the Orthodox faith though many Serbs were Moslems, and stubbornly resisted the Central Powers in World War I. Serbian Belgrade was the seat of the Yugoslav national government, lending credence to the claim of the minorities that the Serbs dominated the state. It was the Serbs' violent protest to Regent Paul's accord with Hitler and their overthrow of the government in March 1941 that precipitated the German attack the following month, and it was from among the Serbs that the Chetniks rose to resist the occupation forces.
Next in numbers to the Serbs were the Croats, some three and three-quarter million, inhabiting the northwestern part of Yugoslavia. The traditional capital of the Croats was Zagreb, and their territory was part of the Austro-Hungarian Empire until the end of World War I. The Croats were culturally more advanced than the Serbs, were western European in their outlook, and the majority professed Catholicism. Although their language was related closely to that of the Serbs, the Croats used the Latin alphabet. German influence among the Croats in the pre-1941 period was strong, and it was on the tradi-
