A person who actively works against a revolution and tries to restore the old political system that was overthrown.
From counterrevolution + -ist (a person who practices or supports). The -ist suffix comes from Latin -ista. This noun form became common in political discourse during the 19th and 20th centuries.
Counterrevolutionists usually lose because they're defending something that was already unpopular enough to overthrow—they're trying to resurrect the dead, while revolutionaries are driving forward.
