During the eighteenth century in England the Whig Party was a loosely organised coalition of political leaders that opposed any hint of arbitrary authority that might emanate from the monarchy and royally appointed officials in government. Like the radical Whig pamphleteers, they also viewed themselves as defenders of liberty, which is one reason why many American leaders, even though not organised as a political party, called themselves whigs. During the 1830s and 1840s in the United States, there was a Whig party that opposed the policies of Andrew Jackson, Martin Van Buren, and other members of the Democratic Party.
