Originally a term for Scottish Presbyterians, the name came to imply nonconformity and rebellion and was applied in 1679 to those who wanted to exclude James, the Catholic duke of York (later James II), from succession to the throne of England. The Whigs were opposed by the Tory faction in that struggle but later represented the aristocratic, landowning families and financial interests of the wealthy middle classes. They maintained power through patronage and connections in Parliament, but there was no distinct party until 1784, when Charles James Fox represented the interests of religious dissenters, industrialists, and others who sought parliamentary reform. After 1815 and following various party realignments, the political group became the Liberal Party
