Exclusion Bill crisis, 1678-81. During the reign of Charles II of England, the initiative to exclude the king’s Roman Catholic brother, James, the Duke of York (later King James II and VII) from the thrones of England and Ireland. The Tories opposed the exclusion, while the "Country party", soon to be the Whigs, supported it. Despite two failed attempts to reestablish Parliment and pass the bill, the Crown was sucessfully able to label the Whigs as subversives and closet nonconformists. By 1681, the mass movement that had temporarily supported the initiative had died down, and the bill was dropped. Wikipedia
