Jiaozhou Bay is a deep-water bay located on the southern coast of Shandong Province, China. This strategic waterway became a focal point during the late 19th century due to its significance in maritime trade and military navigation, especially in the context of Western imperialism and the rise of foreign concessions in China. The area became a symbol of foreign domination as it was leased to Germany in 1898, showcasing the broader impact of imperial powers on China's territorial integrity and sovereignty.
