Cass, Lewis (1782–1866)

Lewis Cass (b. 9 October 1782; d. 17 June 1866), U.S. general, secretary of state, diplomat, Democratic presidential candidate in 1848. Characterized as hawkish and anglophobic, Cass was one of the nineteenth century's leading exponents of Manifest Destiny in the United States. Cass backed the annexation of Texas and argued in 1847 that the Mexican War offered the United States a great opportunity for westward expansion. He called upon the Senate to approve the military expenditure necessary to force Mexico to surrender all its land north of the Sierra Madre. Cass urged the annexation of the Yucatán Peninsula in 1848, and he was an advocate of U.S. political and economic interests in Central America in the 1850s.

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:
