Dumnonii. British tribe and civitas. The Dumnonii seem to have occupied the whole of the south-west peninsula, and parts of southern Somerset. They issued no coinage, they had no large nucleated settlements which acted as political focuses, and there is no evidence of a dynasty of Dumnonian kings. They were therefore probably a loose confederation of small tribal groups with a common ancestry. They appear to have accepted the Roman conquest without resistance and as a result few garrison forts were placed in their territory. The Romans granted them civitas status, and the town of Exeter (Isca Dumnoniorum) became their administrative centre.

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.
