The first Anglo-Japanese Alliance was an alliance between Britain and Japan, signed in January 1902. The alliance was signed in London at Lansdowne House on 30 January 1902 by Lord Lansdowne, British Foreign Secretary, and Hayashi Tadasu, Japanese diplomat. A diplomatic milestone that saw an end to Britain's "Splendid isolation" (a policy of avoiding permanent alliances), the Anglo-Japanese alliance was renewed and expanded in scope twice, in 1905 and 1911, playing a major role in World War I before the alliance's demise in 1921 and termination in 1923.The main threat for both sides was from Russia. France was concerned about war with Britain and, in cooperation with Britain, abandoned its ally, Russia, to avoid the Russo-Japanese War of 1904. However, Britain siding with Japan angered the United States and some British dominions, whose opinion of the Empire of Japan worsened and gradually became hostile.
