summaryLong: The Anglo-Japanese Alliance  was an alliance between the United Kingdom and the Empire of Japan which was effective from 1902 to 1923. The treaty creating the alliance was signed at Lansdowne House in London on 30 January 1902 by British foreign secretary Henry Petty-Fitzmaurice, 5th Marquess of Lansdowne and Japanese diplomat Hayashi Tadasu. After the preceding era of unequal treaties enforced on Asian countries including Japan, the alliance was a military pact concluded on more equal terms between a Western power and non-Western nation. It reflected the success of Meiji era reforms that modernized and industrialized Japan's economy, society and military, which enabled Japan to extract itself from the inferior position it had previously shared with other Asian countries like China, which had been subordinated to Western empires either through formal colonial acquisition or unequal treaties.
