Caen, treaty of

Caen, treaty of, 1091. On his death-bed in 1087 William the Conqueror gave England to his second son William Rufus, and the duchy of Normandy to his first son, Robert. But each retained estates and supporters in the other's territories and relations broke down. In 1091 Rufus led an expedition to Normandy, forcing Robert to a treaty at Caen or Rouen. Rufus kept his Normandy possessions, but agreed to help Robert recover lost estates in Cotentin and Maine. Each named the other as successor should there be no children. They joined forces to dispossess their younger brother Henry (later Henry I) in Cotentin but by 1094 were at war with each other again.

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.
