Serbia

During World War II, several provinces of the Kingdom of Yugoslavia corresponding to the modern-day state of Serbia were occupied by the Axis Powers from 1941 to 1944. 

Most of the area was occupied by the Wehrmacht and was organized as separate territory under control of the German Military Administration in Serbia. 

Other parts of modern Serbia that were not included in the German-administered territory were occupied and annexed by neighboring Axis countries: Syrmia was occupied and annexed by the Independent State of Croatia, Bačka was occupied and annexed by Hungary, southeastern Serbia was occupied and annexed by Bulgaria, and southwestern Serbia was occupied and annexed by Italy and included in the Italian protectorates of Albania and Montenegro.

The area under control of the German Military Administration in Serbia was initially occupied by the Germans. 

It was later occupied mostly by Bulgarian troops, but remained under German military authority. 

On stamps and coins this territory was referred to as Serbia,non-primary ] and, according to Professor Paul N. Hehn, its official name was the Territory of the Military Commander in Serbia. 

This territory had two successive Serbian puppet governments which were under the control of the German military authorities. 

The first short-lived puppet government was known as the Commissioner Government and was led by Milan Aćimović. The second puppet government was known as the Government of National Salvation and was led by Milan Nedić.

Of the Jewish population of about 12,500 in Serbia, under German occupation controlled by Hungary or the Independent State of Croatia, approximately 11,000 Jews were murdered.


Russia

The Eastern Front of World War II was a theatre of conflict between the European Axis powers and co-belligerent Finland against the Soviet Union (USSR), Poland and other Allies, which encompassed Central Europe, Eastern Europe, Northeast Europe (Baltics), and Southeast Europe (Balkans) from 22 June 1941 to 9 May 1945. 

It was known as the Great Patriotic War in the Soviet Union and some of its successor states, while everywhere else it was called the Eastern Front.

The battles on the Eastern Front of the Second World War constituted the largest military confrontation in history. 

They were characterised by unprecedented ferocity, wholesale destruction, mass deportations, and immense loss of life due to combat, starvation, exposure, disease, and massacres. 

Of the estimated 70–85 million deaths attributed to World War II, around 30 million occurred on the Eastern Front, including 9 million children.


The Eastern Front was decisive in determining the outcome in the European theatre of operations in World War II, eventually serving as the main reason for the defeat of Nazi Germany and the Axis nations.

The two principal belligerent powers were Germany and the Soviet Union, along with their respective allies. Though never engaged in military action in the Eastern Front, the United States and the United Kingdom both provided substantial material aid to the Soviet Union in the form of the Lend-Lease program. 

The joint German–Finnish operations across the northernmost Finnish–Soviet border and in the Murmansk region are considered part of the Eastern Front. 

In addition, the Soviet–Finnish Continuation War is generally also considered the northern flank of the Eastern Front.

France

France was the largest military power to come under occupation as part of the Western Front in World War II

The Western Front was a military theatre of World War II encompassing Denmark, Norway, Luxembourg, Belgium, the Netherlands, the United Kingdom, France, Italy, and Germany. 

The Western Front was marked by two phases of large-scale combat operations.

The first phase saw the capitulation of the Netherlands, Belgium, and France during May and June 1940 after their defeat in the Low Countries and the northern half of France, and continued into an air war between Germany and Britain that climaxed with the Battle of Britain.

After capitulation, France was governed as Vichy France headed by Marshal Philippe Pétain. From 1940 to 1942, while the Vichy regime was the nominal government of all of France except for Alsace-Lorraine, the Germans and Italians militarily occupied northern and south-eastern France.

   

Albania

In Albania, World War II began with its invasion by Italy in April 1939. 

Fascist Italy set up Albania as its protectorate or puppet state. 

The resistance was largely carried out by Communist groups against the Italian (until 1943) and then German occupation in Albania. 

At first independent, the Communist groups united in the beginning of 1942, which ultimately led to the successful liberation of the country in 1944.

The Center for Relief to Civilian Populations (Geneva) reported that Albania was one of the most devastated countries in Europe. 

60,000 houses were destroyed and about 10% of the population was left homeless.

In spite of Albania’s long-standing protection and alliance with Italy, on 7 April 1939 Italian troops invaded Albania, five months before the start of the Second World War. 

The Albanian armed resistance proved ineffective against the Italians and, after a short defense, the country was occupied. On 9 April 1939 the Albanian king, Zog I fled to Greece.

In an effort to win Albanian support for Italian rule, Ciano and the Fascist regime encouraged Albanian irredentism in the directions of Kosovo and Chameria. 

Despite Jacomoni’s assurances of Albanian support in view of the promised “liberation” of Chameria, Albanian enthusiasm for the war was distinctly lacking. 

The few Albanian units raised to fight during the developments of the Greco-Italian War (1940–1941) alongside the Italian Army mostly “either deserted or fled in droves”. 

Albanian agents recruited before the war, are reported to have operated behind Greek lines and engaged in acts of sabotage but these were few in number. 

Support for the Greeks, although of limited nature, came primarily from the local Greek populations who warmly welcomed the arrival of the Greek forces in the southern districts

 

Great Britain

When the United Kingdom declared war on Nazi Germany in September 1939 at the start of World War II, the UK controlled to varying degrees numerous crown colonies, protectorates and the Indian Empire.

It also maintained unique political ties to four of the five independent Dominions—Australia, Canada, South Africa, and New Zealand[note 1]—as co-members (with the UK) of the then “British Commonwealth”.

In 1939 the British Empire and the Commonwealth together comprised a global power, with direct or de facto political and economic control of 25% of the world’s population, and of 30% of its land mass.

The contribution of the British Empire and Commonwealth in terms of manpower and materiel was critical to the Allied war-effort.

From September 1939 to mid-1942, the UK led Allied efforts in multiple global military theatres.

Commonwealth, Colonial and Imperial Indian forces, totalling close to 15 million serving men and women, fought the German, Italian, Japanese and other Axis armies, air-forces and navies across Europe, Africa, Asia, and in the Mediterranean Sea and the Atlantic, Indian, Pacific and Arctic Oceans.

Commonwealth forces based in Britain operated across North western Europe in the effort to slow or stop Axis advances. Commonwealth air forces fought the Luftwaffe to a standstill over Britain, and Commonwealth armies fought and destroyed Italian forces in North and East Africa and occupied several overseas colonies of German-occupied European nations.

Following successful engagements against Axis forces, Commonwealth troops invaded and occupied Libya, Italian Somaliland, Eritrea, Ethiopia, Iran, Iraq, Syria, Lebanon, Iceland, the Faroe Islands, and Madagascar.

The Commonwealth defeated, held back or slowed the Axis powers for three years while mobilizing its globally-integrated economy, military, and industrial infrastructure to build what became, by 1942, the most extensive military apparatus of the war. 

These efforts came at the cost of 150,000 military deaths, 400,000 wounded, 100,000 prisoners, over 300,000 civilian deaths, and the loss of 70 major warships, 39 submarines, 3,500 aircraft, 1,100 tanks and 65,000 vehicles.

During this period the Commonwealth built an enormous military and industrial capacity.

Britain became the nucleus of the Allied war-effort in Western Europe, and hosted governments-in-exile in London to rally support in occupied Europe for the Allied cause.

Canada delivered almost $4 billion in direct financial aid to the United Kingdom, and Australia and New Zealand began shifting to domestic production to provide material aid to US forces in the Pacific.Following the US entry into the war in December 1941, the Commonwealth and the United States coordinated their military efforts and resources globally.

As the scale of the US military involvement and industrial production increased, the US undertook command in many theatres, relieving Commonwealth forces for duty elsewhere, and expanding the scope and intensity of Allied military efforts.

Co-operation with the Soviet Union also developed.

However, it proved difficult to co-ordinate the defence of far-flung colonies and Commonwealth countries from simultaneous attacks by the Axis powers.

In part this difficulty was exacerbated by disagreements over priorities and objectives, as well as over the deployment and control of joint forces.

The governments of Britain and Australia, in particular, turned to the United States for support.

Although the British Empire and the Commonwealth countries all emerged from the war as victors, and the conquered territories returned to British rule, the costs of the war and the nationalist fervour that it had stoked became a catalyst for the decolonisation which took place in the following decades.
