The Korea-Japan Treaty, formally known as the Korea-Japan Treaty of 1905, was an agreement that established Japan's protectorate over Korea. This treaty followed Japan's victory in the Russo-Japanese War and aimed to solidify Japan's influence in the region. It was signed on November 17, 1905, and marked a significant shift in Korea's political landscape, as it limited Korea's diplomatic sovereignty. The treaty was imposed on Korea without proper negotiation, leading to widespread resentment among Koreans. It laid the groundwork for Japan's formal annexation of Korea in 1910, which lasted until the end of World War II. The treaty is often viewed as a pivotal moment in the history of both Korea and Japan.
