Petrópolis (pətrô´pŏŏlēs), city (1996 pop. 267,704), Rio de Janeiro state, SE Brazil, picturesquely situated in hills just N of Rio de Janeiro. It is a fashionable resort, with a healthful climate, beautiful wooded estates, flower gardens, and tree-lined avenues. There are also industries producing textiles, coffee, and cereals. It was colonized by Bavarian immigrants in 1845 and soon afterward became the summer residence of the emperor Dom Pedro II, for whom the city is named. Successive presidents made it the unofficial summer capital of Brazil. Among its many fine buildings are a Gothic cathedral and the old imperial palace, which is now a museum containing possessions of Portuguese and Brazilian royalty. Petrópolis has a university.

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:
