Anglo-Japanese treaty

Anglo-Japanese treaty, 1902. Concluded on 30 January to improve British security against France and Russia in the Far East, each party agreed to fight only if the other became involved in war with at least two other powers. The treaty promised to localize any war, and facilitated Japan's decision to attack Russia in 1904. It was renewed in 1905, each party agreeing to assist the other in a war with only one opponent. From 1911 the British also tried to use the alliance as a restraining influence on Japan. American objections brought about its demise in 1921–2.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
