Madrid, Treaty of (1750)

Treaty of (1750) Madrid, agreement between Spain and Portugal that affected Brazil and the Río de la Plata. In the Treaty of Madrid, Portugal ceded to Spain Colônia, an important center of contraband trade, lands adjoining the Río de la Plata, and its free navigation of the river in exchange for two areas along the border of Brazil and an agreement to move seven Jesuit missions (along with thirty thousand Guaraní Indians) located in one of the territories. Signed on 3 January 1750, the treaty's terms faced vehement opposition in both countries. Among its detractors were the powerful Portuguese minister Pombal (Sebastião José de Carvalho e Melo), the future Charles III (1716–1788) of Spain, and the Jesuits, who protested but obeyed. The Portuguese did the most to subvert the treaty, but the Jesuits in Spain (and government supporters of the order) suffered the most from its political repercussions when the attempt to evacuate the missions was met with bloody resistance in 1754 and 1756. The Treaty of Madrid was annulled by the Treaty of El Pardo (12 February 1761) which restored the Jesuits to their missions but renewed territorial disputes.

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:

  • 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.
