The
Japan–Korea Treaty of 1905, also known as the
Eulsa Treaty or
Japan–Korea Protectorate Treaty, was made between the
Empire of Japan and the
Korean Empire in 1905. Negotiations were concluded on November 17, 1905. The treaty deprived Korea of its diplomatic sovereignty and made Korea a protectorate of Japan. It was influenced by Japan's victory in the
Russo-Japanese War in 1905.
