After Albanian declaration of independence in 1912 land division between Albania and Greece was finally solved under the force of the Great Powers (Austria-Hungary and Italy) with the Florence Protocol. Relations did not improve until 1939 with the occupation of Albania by Italy. Greek and Albanian forces came into conflict during the Greco-Italian War even though during the Axis Occupation of Greece the Greek and Albanian resistance groups were in close contact and even exchanged information about the Nazi occupation forces.
