What's the difference between i.e. and e.g.?
British political party, 1657, in part perhaps a disparaging use of whigg "a country bumpkin" (1640s); but mainly a shortened form of Whiggamore (1649) "one of the adherents of the Presbyterian cause in western Scotland who marched on Edinburgh in 1648 to oppose Charles I." Perhaps originally "a horse drover," from dialectal verb whig "to urge forward" + mare. In 1689 the name was first used in reference to members of the British political party that opposed the Tories. American Revolution sense of "colonist who opposes Crown policies" is from 1768. Later it was applied to opponents of Andrew Jackson (as early as 1825), and taken as the name of a political party (1834) that merged into the Republican Party in 1854-56.
[I]n the spring of 1834 Jackson's opponents adopted the name Whig, traditional term for critics of executive usurpations. James Watson Webb, editor of the New York Courier and Enquirer, encouraged use of the name. [Henry] Clay gave it national currency in a speech on April 14, 1834, likening "the whigs of the present day" to those who had resisted George III, and by summer it was official. [Daniel Walker Howe, "What Hath God Wrought," 2007, p.390]Whig historian is recorded from 1924. Whig history is "the tendency in many historians ... to emphasise certain principles of progress in the past and to produce a story which is the ratification if not the glorification of the present." [Herbert Butterfield, "The Whig Interpretation of History," 1931]
members of two opposing political parties or factions in England, particularly during the 18th century. Originally "Whig" and "Tory" were terms of abuse introduced in 1679 during the heated struggle over the bill to exclude James, duke of York (afterward James II), from the succession. Whig-whatever its origin in Scottish Gaelic-was a term applied to horse thieves and, later, to Scottish Presbyterians; it connoted nonconformity and rebellion and was applied to those who claimed the power of excluding the heir from the throne. Tory was an Irish term suggesting a papist outlaw and was applied to those who supported the hereditary right of James despite his Roman Catholic faith.
