At the beginning of WWI, which country established a naval blockade to prevent German ships from escaping into the Atlantic?

At the beginning of World War I, Britain established a naval blockade against Germany as part of its strategy to weaken the Central Powers. The British Royal Navy was the most powerful naval force at the time, and the blockade aimed to restrict Germany's access to international trade and resources. By preventing German ships from escaping into the Atlantic, Britain sought to cut off vital supplies, including food and raw materials, thereby crippling the German war effort. This blockade was significant in shaping the course of the war, as it contributed to shortages in Germany and increased pressure on the German economy and military capabilities.

Other nations like France and Russia had their naval forces, but they did not implement a blockade of the scale or strategic importance that Britain did. The United States, while eventually entering the war, was neutral at the onset and did not engage in naval blockade activities during the early stages of the conflict. Understanding Britain's role in establishing the naval blockade is crucial for grasping how the naval warfare aspects influenced World War I.
