O'Connor, Arthur

O'Connor, Arthur (1763–1852). Irish republican. Born in Mitchelstown (Co. Cork), into a landed family, his background was protestant but he was a sceptic. He sat in the Dublin Parliament as a follower of Grattan (1791–5), speaking in favour of catholic emancipation, but in 1796 joined the United Irishmen and conducted negotiations for the French invasion of that year. Imprisoned in Dublin for six months for seditious libel in 1797, he was arrested again on his way to France in February 1798. Tried for high treason and acquitted, he was detained on lesser charges but released into exile in France in 1803. In 1807 he married Condorcet's daughter and settled on an estate near Nemours which had once been Mirabeau's. He became a French citizen in 1818. His rationalism and capacity for organization marked him out as one of the ablest of Irish leaders.

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:

  • 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.
