Greece

The Kingdom of Greece was a state established in 1832 at the Convention of London by the Great Powers (the United Kingdom, Kingdom of France and the Russian Empire). It was internationally recognised by the Treaty of Constantinople, where it also secured full independence from the Ottoman Empire. This event also marked the birth of the first fully independent Greek state since the fall of the Byzantine Empire to the Ottomans in the mid-15th century.

Greek participation in World War II began on 28 October 1940, when the Italian Army invaded from Albania, beginning the Greco-Italian War. The Greek Army was able to halt the invasion temporarily and was able to push the Italians back into Albania. The Greek successes forced Nazi Germany to intervene. The Germans invaded Greece and Yugoslavia on 6 April 1941, and overran both countries within a month, despite British aid to Greece in the form of an expeditionary corps. The conquest of Greece was completed in May with the capture of Crete from the air by the Fallschirmjäger (German paratroopers).
