noun
rioter; ruffian; violent troublemaker
A somewhat old-fashioned or literary term for a person who engages in violent, disorderly conduct, especially in a group or mob context. Not a common modern colloquial word.
狼藉者が町で暴れていると聞いて、人々は家に閉じこもった。
Hearing that ruffians were rampaging through the town, people shut themselves in their homes.
乱暴者 is a more general term for a violent or rough person, whereas 狼藉者 specifically suggests participation in a riot or mob violence.
Compound of 狼藉 (lawlessness, violence) and 者 (person). The exact historical derivation is uncertain, but the word has been used in literary and historical contexts to describe rioters or ruffians.
