The German invasion of Greece, also known as the Battle of Greece or Operation Marita, were the attacks on Greece by Italy and Germany during World War II. The Italian invasion in October 1940, which is usually known as the Greco-Italian War, was followed by the German invasion in April 1941. German landings on the island of Crete came after Allied forces had been defeated in mainland Greece. These battles were part of the greater Balkans Campaign of the Axis powers and their associates.
The Greco-Italian War, also called the Italo-Greek War, Italian campaign in Greece, Italian invasion of Greece, and War of '40 in Greece, took place between Italy and Greece from 28 October 1940 to 23 April 1941. This conflict began the Balkans campaign of World War II between the Axis powers and the Allies, and eventually turned into the Battle of Greece with British and German involvement. On 10 June 1940, Italy declared war on France and the United Kingdom. By September 1940, the Italians had invaded France, British Somaliland and Egypt. This was followed by a hostile press campaign in Italy against Greece, accused of being a British ally. A number of provocations culminated in the sinking of the Greek light cruiser Elli by the Italians on 15 August. On 28 October, Mussolini issued an ultimatum to Greece demanding the cession of Greek territory, which the Prime Minister of Greece, Ioannis Metaxas, rejected.
The military history of Greece during World War II began on 28 October 1940, when the Italian Army invaded Greece from Albania, beginning the Greco-Italian War. The Greek Army temporarily halted the invasion and pushed 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, although the Fallschirmjäger suffered such extensive casualties in this operation that the Oberkommando der Wehrmacht abandoned large-scale airborne operations for the remainder of the war. The German diversion of resources in the Balkans is also considered by some historians to have delayed the launch of the invasion of the Soviet Union by a critical month, which proved disastrous when the German Army failed to take Moscow.
The Battle of Bizani took place in Epirus on 4–6 March [O.S. 19–21 February] 1913.

The Battle of Pindus took place in the Pindus Mountains in Epirus and West Macedonia, Greece, from 28 October – 13 November 1940. The battle was fought between the Greek and the Italian armies during the first stages of the Greco-Italian War. The elite Italian 3rd Alpine Division "Julia" invaded Greece from the Pindus sector. After its initial advance, the division was surrounded by the Greek army and forced to retreat after suffering heavy losses. In the aftermath, the Greeks were able to push back the Italians, advancing deep into Albanian territory.
Ubaldo Soddu was an Italian general and politician who held the position of Deputy Chief of Staff of the Army and Undersecretary of State for War during the initial phases of World War II. On 13 June 1940, immediately after the outbreak of hostilities with France and the United Kingdom, he assumed the position of deputy chief of the General Staff. Promoted to army general, he replaced general Sebastiano Visconti Prasca as commander of the Albanian Higher Troop Command during the Greco-Italian War on 8 November 1940.

The Battle of Elaia–Kalamas took place in Epirus on 2–8 November 1940. The battle was fought between the Greeks and the Italians during the initial stage of the Greco-Italian War in World War II. The Italian Army, deployed on the Greek-Albanian border, launched an offensive against Greece on 28 October 1940. The main thrust of the Italian invasion occurred in the Epirus sector, with a further flanking move through the Pindus mountains. In Epirus, the Greeks held the Elaia–Kalamas river line, and, even though the Greek army was outnumbered, the local Greek forces under Major General Charalambos Katsimitros stopped the Italian advance. Along with the Italian failure in the Battle of Pindus, these Greek successes signified the complete failure of the Italian invasion, leading to the dismissal of the Italian commander in Albania, Sebastiano Visconti Prasca, on 9 November. In the next few weeks the Greek forces initiated a counteroffensive that forced the Italians to retreat deep into Albania.
The Capture of Klisura Pass was a military operation that took place during 6–11 January 1941 in southern Albania, and was one of the most important battles of the Greco-Italian War. The Italian Army, initially deployed on the Greek-Albanian border, launched a major offensive against Greece on 28 October 1940. After a two-week conflict, Greece managed to repel the invading Italians in the battles of Pindus and Elaia–Kalamas. Beginning on 9 November, the Greek forces launched a major counteroffensive and penetrated deep into Italian-held Albanian territory. The Greek operations culminated with the capture of the strategically important Klisura Pass in January 1941.
