Port Sudan (sōōdăn´), city (1993 pop. 308,195), NE Sudan, on the Red Sea. The country's major seaport, it handles the bulk of Sudan's foreign trade. The city is also a rail terminus that serves a rich, cotton-growing area of the Nile Valley. Port Sudan has an oil refinery and a pipeline to carry oil to Khartoum, completed in 1977. The city also has an international airport. Construction of a railroad linking the Nile and the Red Sea coast in 1905 led to the founding of Port Sudan as a harbor for the region.

Encyclopedia.com 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, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com 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:
Modern Language Association
The Chicago Manual of Style

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com 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.
