People who support, advocate for, or practice feudalism, or scholars who study feudal systems.
Plural of feudalist, derived from feudal plus -ist suffix meaning 'one who practices or believes in.' This term emerged in academic and political contexts during the Industrial Revolution when feudalism was being analyzed and critiqued.
Karl Marx and other political thinkers used 'feudalists' to describe both medieval lords defending their system and 19th-century conservatives who wanted to preserve hierarchical social structures—showing how the same word tracked a real historical struggle.
