France and Britain held a number of meetings in the British capital, London, years before the First World War; This is for the sake of military coordination between the two parties in the event of a war against Germany in the future, and the two parties reached during their meetings on the necessity of imposing a naval blockade on German ports during the war.

Allied ships cut off supplies that were arriving at German ports between 1914 and 1919, thus depriving Germany and Austria of a significant proportion of food and raw materials, and this blockade weakened Germany's power, as it was deprived of trade with its colonies and other countries, This made it plunge into economic isolation, which precipitated its defeat.

Germany was mainly dependent on imports and maritime trade, and it imported the equivalent of 77% of raw materials such as coal, oil and rubber, and during the imposition of the blockade Germany was denied access to its basic needs of these materials in addition to being deprived of food and chemicals such as sodium nitrate. ; It is an essential material for farmers that is used to improve agricultural soil.

British ships imposed their blockade on German ports during the year 1914 AD, coinciding with the outbreak of World War I, and then the British Navy declared later that the North Sea region is a war zone threatening that all ships sailing there will be intercepted, and these decisions have angered America, which was seeking Exploiting the state of war in order to achieve additional profits through the consolidation of its economic relations with the various warring countries.

Britain compensated the American side for the loss of the German market by increasing the percentage of trade exchange between them in a remarkable manner, while the British blockade imposed on the German Navy resulted in disasters for the German side, as the percentage of German imports fell by half during the year 1915.

The decline in German imports of fertilizers and materials needed to improve agriculture caused the collapse of grain cultivation, as well as a decline in meat quantities. As the authorities did not hesitate to confiscate them in order to send them to the soldiers at the front, and the German people were forced to use alternative products.

Germany had suffered from a severe food crisis that made it unable to cope with that war, Germany established the Hindenburg Program, which was aimed at increasing the country's productivity by employing citizens between the ages of 17 and 60 years old.

Germany, in the wake of its suffering, confiscated food and adopted the food ration system. And that is within what is known as war kitchens that provided meager meals for the sake of German citizens, as their food value did not exceed a thousand calories per day, and because of that blockade Germany suffered from famine during the First World War.

That German famine resulted in the deaths of approximately 763,000 German citizens during the end of 1918; This was due to the exposure of most of them to malnutrition and the diseases resulting from it, and that famine played a major role in the outbreak of the revolution that worked to overthrow the rule of Kaiser Wilhelm II (Wilhelm II), and the British blockade continued for months after the surrender of Germany in order to pressure them to accept a treaty For them.
